Spatial distribution and hydrogeochemical evaluations of groundwater and its suitability for drinking and irrigation purposes in kaligonj upazila of satkhira district of Bangladesh

Groundwater is a significant water resource for drinking and irrigation in Satkhira district, Bangladesh. The depletion of groundwater resources and deterioration in its quality are the results of the confluence of factors such as industrialization, intensive irrigation, and rapid population growth. For this reason, this study focused on the evaluation of tubewell water of six unions of Kaligonj upazila in Satkhira district, which is situated in the coastal southwest part of Bangladesh. Major and trace elemental concentrations were assimilated into positive matrix factorization (PMF) to identify potential sources and their respective contributions. Principal component analysis (PCA) revealed that groundwater salinization and manmade activities were the primary causes of heavy metals in the coastal groundwater. Its average pH value was found to be 7.5, while Dissolved oxygen, Total dissolved solids, salinity, and conductivity, with values ranging from 1.18 to 7.38 mg/L, 0.5–4.88 g/L, 0.4–5%, and 0.95 to 8.56 mS/cm, respectively. The total hardness average value was 561.7 mg/L, classified into the very hard water categories, which is why 90% of the tubewell water samples were unfit for household purposes. All samples had an excessive level of arsenic present. The iron concentration of fifteen (15) samples crossed the standard limit according to WHO 2011 value. Around 63% of the samples were of the Na+-K+-Cl--SO42- type, and about 72% were sodium-potassium and alkali types. 98% of samples were covered in chloride and bicarbonate. The findings showed that 45.83% of the groundwater samples had negative Chloroalkaline index (CAIs), while 54.16% had positive. The permeability index (PI) was an average of 73%, and residual sodium carbonate (RSC) averaged 260.2 mg/L, and the findings clearly showed that 80% of the samples weren't appropriate for irrigation. According to the sodium adsorption ratio (SAR) value, 65% of the samples fell into the unsuitable category. These calculations indicated a high overall salinity hazard in the study area, which may be caused by the intrusion of sea water given that the study area is close to the coastal region. Findings compared to standards revealed that the majority of the samples were deemed unfit for drinking and irrigation purposes. Hence, additional attention must be paid to this area to ensure the availability of drinkable water and to preserve sustainable farming practices.

Water Resource Impacts of Irrigation: The Case of the Main Irrigation Canal from the M’Pourie Plain to Rosso in Mauritania

An important factor in determining agricultural production is the availability of irrigation water in the main canal of the M’Pourie plain. This factor affects both the intensification of crops and the size of the irrigation areas. The main Senegal River canal in Rosso, Mauritania, runs across the Plaine of M’Pourie. This study aims to assess the physicochemical quality of the water used for irrigation and agriculture in the main irrigation canal on the M’Pourie plain. The measurements were made from 2021 to 2022, and the following physical and chemical parameters were monitored: pH, temperature, electrical conductivity, salt content, calcium, magnesium, sodium, and potassium; ammonium bicarbonate; chloride; nitrite; nitrate; nitrogen; sulfate; and sodium adsorption ratio (SAR). These measurements were analyzed using volumetric, spectroscopic, and spectrophotometric methods. After conducting statistical analysis and comparing the results with Moroccan quality standards for surface water utilized in irrigation, it has been discovered that the average pH value is 7.51, indicating a neutral state. However, the average nitrite and ammonium values exceed Moroccan standards at 5.16 mg.L-1 and 0.41 mg.L-1, respectively. The water’s low mineralization is attributed to its low electrical conductivity, with an average of 52.2 μS.cm-1. Based on the analysis of the Senegal River water used for irrigation in the M’Pourie plain, it has been determined that its sodium adsorption ratio and electrical conductivity classify it as belonging to class C1S1. This indicates that the water has low salinity and is excellent for irrigation, with a low risk of alkalinization.

The Bilah Sub-Watershed area includes areas that have somewhat critical or semi-critical land so that land use is the result of human efforts in managing the available resources to meet their various needs. This often results in land use not being in accordance with its capabilities. This research aims to examine the chemical properties of several vegetation in Negeri Lama Seberang Village, Bilah Hilir District, Labuhanbatu Regency. The research was carried out from December to March 2024 using a survey method. Soil samples were taken at 3 points for each vegetation and different slopes at depths of 1-10 cm and 10-20 cm using a simple random method. The soil parameters measured were soil acidity (electrometry), soil organic carbon content (Walkley and Black), and soil texture (bouyoucos hydrometer). Soil analysis was carried out at the Laboratory of the Faculty of Agriculture, University of North Sumatra. The results of this research show that on a slope of 0-8% the average soil pH value is 4.61% and organic C is 1.04%, while on a slope of 8-15% the average soil pH value is 4.46% and C -organic 0.91%. On a slope of 0-8% the average value of the clay fraction is 20.27%, the dust fraction is 15.02% and the sand fraction is 64.41%, while on a slope of 8-15% the average value of the clay fraction is 27.48%, the dust fraction 19.87%, and sand fraction 52.63%.

The effects of fortification of yogurt with various functional flours on survival and growth of probiotic bacteria and sensory properties of the yogurt

PurposeThe purpose of this study is to determine the viability of Lacticaseibacillus rhamnosus GR-1 (L. rhamnosus GR-1) in five yogurt samples with or without quinoa, chickpea, soybean and rice flour over various fermentation periods and refrigerated storage durations, with a focus on exploring the potential of functional foods, which provide health benefits beyond nutritional value. Additionally, the study aimed to evaluate consumer acceptance of yogurt fortified with functional flour. Using a nine-point hedonic scale, from 1 (dislike extremely) to 9 (like extremely), participants rated appearance, flavour, texture and overall acceptability.Design/methodology/approachThe samples were inoculated with the probiotic strain L. rhamnosus GR-1 and fermented for 0, 2, 4 and 6 h at 38°C, followed by refrigerated storage at 4°C for 1, 15 and 30 days, respectively. Microbial enumeration was performed throughout fermentation and storage to assess the viability of L. rhamnosus GR-1. A sensory evaluation involving 86 participants was conducted to assess the consumer acceptability of the yogurt samples.FindingsNotably, L. rhamnosus GR-1 achieved viable counts of 108 colony-forming units per mL in all treatments at all fermentation time points. Over the 30-day storage period, no statistically significant differences (p < 0.05) in average pH values were observed among the five treatments, and within each treatment, pH levels remained stable, with an overall mean of 4.2 ± 0.64. Treatment 4, which featured rice flour fortification, received higher hedonic scores from sensory panellists in terms of appearance, flavour, texture and overall acceptability. These findings indicate that incorporating functional flours in conjunction with cow’s milk effectively promotes and preserves the viability of L. rhamnosus GR-1 in yogurt.Originality/valueExploring the potential of probiotic yogurt enriched with diverse functional flours to enhance nutritional content and health benefits as well as attract new consumers, this study addressed a critical gap in understanding consumer perceptions and generated insights for creating innovative and health-promoting dairy products.

Formulation and Antioxidant Activity Analysis of Jotang Herb (Acmella paniculata) Extract Mask Cream

Pollution in the environment can increase the production of reactive oxygen species (ROS), which can reduce the amount of antioxidants in the skin. Antioxidants are compounds that can inhibit oxidation reactions by binding to free radicals and reactive molecules. Herbaceous plant jotang (Acmella paniculata) has secondary metabolites such as flavonoids, alkaloids, tannins, and saponins, which can protect the internal and external organs of the body's cells from damage caused by free radicals on the skin. One of the treatment preparations used for the skin is a cream mask, as the use or application at the final level of skin care can improve cleanliness and health and stimulate and repair skin cells. This study aims to determine a formula that has a good antioxidant value using the DPPH method (2,2-diphenyl-1-pikrilhidrazyl). In this study, preparations were made with 3 formulas, namely Formula I (1% w/w), Formula II (10%w/w), and Formula 0 (Control). Evaluation of physical properties included organoleptic tests, homogeneity tests, spreadability tests, pH tests, viscosity tests, cream-type tests, and antioxidant tests. The result showed that the organoleptic test had a cream mask dosage in the form of semi-solid, distinctive jotang odor, light and dark green, had a homogeneous dosage form, spreadability around 5.1-5.7 with an average pH value of 6, had a good viscosity value and had a type of cream M/A and a high antioxidant value in formula II (10% w/w ) with an IC50 value of 21.959 μg/ml. Based on statistical tests, significant results were obtained of 0.000p (0.05) so that it can be interpreted that there was a significant difference in each concentration of jotang herb extract to the resulting IC50 value.

Seasonal quality and statistical assessment of physicochemical properties and base saturation of Hadejia-Nguru wetland soils, Northwest/Eastern Nigeria

Abstract The evaluation of Hadejia-Nguru wetland soils was carried out for two consecutive dry seasons. Standard analytical techniques were adopted to analyze the samples and statistical models were used to assess the spatial and temporal distribution of the parameters selected. The average pH values of the soil samples were mostly alkaline, and all the measured values were also within the approved standards. Experimental results revealed a significantly positive correlation between Ca and Mg for both seasons as indicated by the p-values and a high coefficient of determination (R2) for both metals with cation exchange capacity (CEC) values as the predictors. The regression analysis showed that the changes in CEC and pH levels in the soil were dependent on changes in Ca and Mg content of the soil. The data obtained showed that the increase in pH is directly proportional to the CEC and base saturation of the soils. A higher percentage of Ca than other cations (Mg, K and Na) was observed from the base saturation of the soils. The pH, base saturation, and CEC levels in the soils are suitable for most crops grown in the area, which has the potential to support a wide range of crops with further exploration.

Application of Multispectral Drone for Quantitative Assessment of the Fertilizer Requirement for the Up-country Tea Plantation in Sri Lanka

&#x0D; &#x0D; &#x0D; The amount of chlorophyll content and structure would differ between diseased and healthy plants, affecting the NDVI values, which strongly correlated with fertilizer applications. The primary goal of this research is to use a multispectral drone to quantify the fertilizer requirements for the sample tea plantations in Nuwara Eliya, Sri Lanka. In contrast, a drone with multispectral imaging camera sensors was used to gather images covering blue, green, red, red-edge, and near-infrared bands. The collected images were analyzed, and geographic outputs were generated. The processed geospatial data were used to determine the NDVI values for each tea field, and the general health of the tea was estimated. Finally, NDVI readings and geospatial products from each tea field related to soil analytical data. Based on the NDVI values, 25 selected soil samples were collected using sampling plots. The concentrations of pH, electrical conductivity (EC), nitrogen (N), phosphorus (P) and potassium (K) were then determined using standard soil testing procedures. Finally, soil analysis results were combined with the geospatial data. In addition, the amount of Dolomite for each tea field was calculated based on the pH values, and the amount of nitrogen, phosphorus, and potassium was calculated as yield and area and based on the number of tea bushes. The tea plantations show an NDVI range of 0.76-0.81 for low healthy tea, 0.81-0.86 for medium healthy tea and 0.86-0.97 for healthy tea. The healthiness percentages of one of the tea plantation show 18% healthy tea, 54% medium healthy tea, and 22% low healthy tea. Conversely, the healthiness percentages of the other tea plantation show 44% healthy tea, 39% medium healthy tea and 17% low healthy tea based on the NDVI value. The average value of pH, EC, N, P, and K are 4.84, 41.58, 0.29, 0.11, 0.04 in tea plantations, respectively, and in other planation, average values of pH, EC, N%, P%, and K% are 4.83, 40.96, 0.36, 0.25, 0.04 respectively. The amounts of Dolomite for each tea field are 2685.32 Kg/ha and 977.34 Kg/ha. In one tea field, an average annual NPK fertilizer need is 685 kg per hectare, 94 kg per hectare, and 269 kg per hectare, respectively. Additionally, calculations based on tea bushes indicate that the average annual NPK fertilizer requirements are 685 kg, 89 kg, and 254 kg, respectively. Other tea filed average annual NPK fertilizer need is 88 kg per hectare, 24 kg per hectare, and 68 kg per hectare, respectively. Additionally, calculations based on tea bushes indicate that the average annual NPK fertilizer requirements are 90 kg, 25 kg, and 70 kg, respectively. However, these values have several limitations, such as climate, soil, plant, and cultural practices. This study mainly focuses on and creates Insights into Plant Health by assessing precise plant-level data using a multispectral imaging system. It had not been correlated with other factors except soil conditions.&#x0D; Keywords: Unmanned aerial vehicles, Multispectral, NDVI, Tea, Fertilizer&#x0D; &#x0D; &#x0D;

The role of Lactic Acid Bacteria Microbiota in Determining the pH Value of Newborn Faeces

The low pH is considered a protective mechanism of the body against infections by providing unfavourable conditions for their causers. Analysis of fecal pH of newborns have been performed around the world during the last century, and a disturbing tendency has been surveilled due to industrialization and lifestyle change of mothers and their babies. Considering the lack of information of that kind in Bulgaria, we aimed at analysing the pH values of solely breastfed and mix-fed infants, and its relation to the quantity of the found lactic acid bacteria, their taxa and respective metabolic characteristics. A total of fifteen faecal samples were collected from neonates aged 0 to 6 months. The pH values and presence of the Lactobacillaceae family, along with significant representatives of the genus Bifidobacterium were measured and evaluated by using multiplex semi-quantitative PCR. The gathered information about infants’ supplementation intake and feeding was considered. The solely breastfed neonates showed the lowest pH values, and the highest bifidobacterial content in comparison to the mixed-fed. The average pH value is around 5.1, which we interpret as relatively low, compared to the data in the literature. No relation was observed between the probiotic supplementation and the respective stool samples. These results suggest that breastfeeding plays the main role in manifesting gut health, inducing the growth of beneficial bacteria and immunity development. More participants and additional analyses are needed.

Effectivity Of Multi Tray Aerator As Pretreatment Process For Reverse Osmosis Membrane To Utilized As Raw Water At Sungai Itik Village

The community in Sungai Itik Village and its vicinity use river water for their daily needs, such as irrigation for agriculture, fish ponds, washing, bathing, and more. The quality of the river water has an iron (Fe) content of 2,64 mg/L, Total Dissolved Oxygen (TDS) of 347 mg/L, Dissolved Oxygen (DO) of 4,7 mg/L, a temperature of 29°C, and a pH of 5,4. The iron (Fe) content exceeds the standards set by PerMenKes No. 32 of 2017, requiring treatment using a multiple-tray aerator. This study aimed to determine the effective distance and number of trays in treating Sungai Itik's raw water, understand the coefficient of gas transfer (KLa) in the aeration process, and find the optimum aeration time. This study employed a multiple-tray aerator consisting of 5 trays with variations in the tray distances at 30 cm, 40 cm, 50 cm, and 60 cm. Three repetitions were performed for each treatment, both without gravel and with gravel. The results of this study showed that the best reduction in Fe content was achieved by the treatment with gravel at a tray distance of 60 cm using 5 trays, resulting in a 6,64% reduction in Fe from an average value of 1,51 mg/L to 1,41 mg/L. The average pH value was 6,19, and the TDS was 890 mg/L. The highest oxygen transfer rate (KLa) was obtained at a tray distance of 60 cm with gravel, averaging 0,2857/minute, and the optimum aeration time was 10 minutes.

Monitoring of rainwater quality in Kandy and Peradeniya, Sri Lanka.

The composition of atmospheric deposition is a measure of air quality, an important aspect of the health of the ecosystem. Consequently, continuous monitoring of atmospheric deposition is crucial to obtain remedial measures to avoid undesirable aspects that would affect living things. In this context, the objective of this study was to determine the rainwater quality at selected locations in Kandy and Peradeniya area of Sri Lanka, namely, Kandy, Polgolla, and University of Peradeniya (UOP), and to identify possible correlations between quality parameters through statistical means. Forty (40) rainwater samples from the UOP site and seven (07) samples each from the Kandy and Polgolla sites were collected from 18 May 2020 to 28 April 2021. The volume-weighted average (VWA) pH values of UOP, Kandy, and Polgolla sites were determined to be 7.44, 7.19, and 7.19, respectively, and moreover, acid rain (pH < 5.6) occurrences were not detected during the sampling period. The VWA values of rainfall, conductivity, salinity, TDS, and hardness at the UOP site were 40.12 mm, 51.93 μS cm-1, 0.0300 ppt, 26.59 mg L-1, and 13.55 mg L-1, respectively. The corresponding values of the Kandy site were 16.52 mm, 64.04 μS cm-1, 0.0361 ppt, 30.80 mg L-1, and 19.49 mg L-1, respectively; and those of the Polgolla site were 33.10 mm, 53.90 μS cm-1, 0.0310 ppt, 25.76 mg L-1, and 19.31 mg L-1, respectively. The VWA values of conductivity, salinity, and TDS were the highest at the Kandy site. Further, the VWA values of hardness at Kandy and Polgollasites were approximately equal, probably due to the spring of Ca2+ and Mg2+ particulates from the dolomite quarry located in Digana area. The most prominent anion was identified as Cl- in bulk deposition at all three sites, while NO3- showed the lowest concentration of all sites. Moreover, very strong significant positive correlations were identified between conductivity-TDS, conductivity-salinity, conductivity-hardness, TDS-hardness, TDS-salinity, salinity-hardness, SO42--Cl-, and NO3--Cl- according to the relevant Pearson correlation coefficients. It is thus concluded that the pollutants come from the same sources, either natural or anthropogenic.

Optimizing nonintubated laryngeal microsurgery: The effectiveness and safety of superior laryngeal nerve block with high-flow nasal oxygen-A prospective cohort study.

Laryngeal microsurgery (LMS) typically requires intubated general anesthesia (ITGA). Although nonintubated general anesthesia (NIGA) with high-flow nasal oxygen (HFNO) can be applied with LMS, a muscle relaxant is required, which can cause apnea and hypercapnia. This study evaluated the effectiveness of a superior laryngeal nerve block (SLNB) in improving safety during LMS. This prospective cohort study enrolled a cumulative total of 61 adult patients received LMS under intravenous general anesthesia and allocated to three groups: ITGA group (n = 18), which patients performed intubation; neuromuscular blocking (NMB) group (n = 21), which patients administrated muscle relaxant without intubation and superior laryngeal nerve block (NB) group (n = 22), which patients performed SLNB without intubation or muscle relaxant. The average (SD) values of PaCO 2 after surgery in ITGA, NMB, and NB group were 50.8 (7.5), 97.5 (24.9), and 54.8 (8.8) mmHg, respectively. The mean postoperative pH values were 7.33 (0.04), 7.14 (0.07), and 7.33 (0.04), respectively. The results were all p < 0.001, and the average pH value of the NMB group was lower than that of the ITGA and NB groups. During the LMS, the mean heart rate (HR) (93.9 [18.1] bpm) and noninvasive blood pressure systolic (NBPs) (143.5 [28.2] mmHg) in the NMB group were higher than those in the ITGA group (HR = 77.4 [13.5] bpm and NBPs = 132.7 [20.8] mmHg) and NB group (HR = 82.3 [17.4] bpm and NBPs = 120.9 [25.0] mmHg). The results of p value by HR and NBPs are p < 0.001. The PaCO 2 and pH values are similar between ITGA group and NB group. Our approach of using HFNO with SLNB was successful for performing nonintubated LMS, enabling the patients to maintain spontaneous breathing and effectively eliminate CO 2 . This approach reduces the risks of hypercapnia and acidosis even when the duration of LMS exceeds 30 minutes.

The average values of pH, pH 24, cooking loss, water holding capacity and shear force values obtained in research groups were 6.46, 5.02, 24.58%, 3.25% and 3.67 kg / cm2 in Honamlı x Saanen; In the same order, 6.46, 5.69, 25.66%, 5.59% and 4.52 kg / cm2 in Saanen and 6.62, 5.27, 22.69%, 2.55% and 4.25 kg / cm2, in the Turkish Hair x Saanen (F1) respectively. It was found in the study that L0 (brightness), a0 (redness) and b0 (yellowness) values were 47.50, 7.51 and 12.67 for Honamlı x Saanen crossbred kids, respectively. The same values were 48.34, 7.74, and 12.62 for Saanen kids and 47.73, 8.01, and 13.20 for Turkish Hair x Saanen crossbred kids, respectively. In the study, the amount of muscle fat in Turkish Hair x Saanen (F1) crossbred kids was found 2.85%. While there was no difference in oleic acid content among genotypes, the ω-6 fatty acids linoleic and arachidonic were detected in the Saanen kids with a maximum of 10.67% and 4.98%, respectively (P&lt; 0.05). According to findings, It was found that Honamlı x Saanen (F1) cross kids have shown beter performance for many traits than others. Therefore, Saanen farms which has no need young breeding animal can use Honamlı bucks as patternal line for the butchered kid production. This application can be introduced to the sector.

ASSESSMENT OF THE ECOLOGICAL STATE OF RURAL SETTLEMENTS BY INDICATORS OF DRINKING WATER QUALITY IN THE CONTEXT OF SUSTAINABLE DEVELOPMENT

The purpose of the study was to assess the state of ecological development of rural rural areas of the amalgamated territorial communities of Zhytomyr district based on drinking water quality indicators of non-centralised water supply sources to ensure their sustainable development. It was found that the average pH value was within the current standard, which indicates an excellent environmental condition for this indicator. The average content of nitrates in drinking water, which in all the studied communities exceeded the standard by 1.4 to 3.5 times, was assessed at only one point. The average concentration of total iron exceeded the current standard by 1.9 times only in the rural settlements of the Liubar community. Satisfactory water quality, in terms of total iron content, was recorded in 50 per cent of the surveyed communities. In 70 per cent of the studied communities, the average value of total hardness was recorded at a level higher than 7.0 mmol/dm3, which indicates, according to European legislation, a poor condition of drinking water. Thus, having assessed the ecological state of rural areas in terms of drinking water quality, it was found that most of the studied communities have a satisfactory state of the territories, as the total number of points varied between 2.25-3.3 points. And the greatest contribution to the decline in the level of environmental development of rural settlements is made by the indicators of nitrate content in drinking water and its hardness.

Comparative study of the quality of breast meat of free-range chicken (Gallus gallus domesticus) and conventional chicken (Gallus gallus).

This study compares the physicochemical characteristics of breast meat (Pectoralis major) from conventional chicken and free-range chicken production systems. Analyses of pH, instrumental color measurement, weight loss from cooking (WLC), and water retention capacity (WRC) were carried out. Average pH values were slightly higher for conventional chicken samples. WLC did not show a significant difference between conventional and free-range chicken samples. The WRC was better and higher for the free-range chicken samples than the conventional ones. The mean values for luminosity (L*) were within the normal range, with slightly higher values for conventional chicken. In chromatids a* and b*, there was a tendency towards a more reddish color for free-range chicken samples. The differences found for types of production can be explained mainly by the difference in age at slaughter, the degree of physical activity, animal feeding, among other characteristics that differentiate an animal raised by the extensive system from the intensive system.

ВЫЯВЛЕНИЕ ПОДОСТРОГО АЦИДОЗА И КЛИНИЧЕСКОГО МАСТИТА У ДОЙНЫХ КОРОВ С ПОМОЩЬЮ ЦИФРОВОЙ СИСТЕМЫ ВНУТРЕННЕГО МОНИТОРИНГА

Subacute acidosis of the rumen is a widespread disease in highly productive dairy cows, which is characterized by a constant abnormally low rumen pH. Mastitis is the most common disease affecting the productivity of animals and the quality of milk. (Research purpose) The research purpose is testing the possibility of detecting subacute acidosis of the scar and clinical mastitis in dairy cows using a digital internal monitoring system. (Materials and methods) The activity, temperature and pH values of the rumen contents were automatically measured every 10 minutes for 4 months in five dairy cows of the Holstein breed. (Results and discussion) It was determined that the average values of the rumen pH differed (P &lt; 0.05) in all five cows (5,58 ± 0,21; 6,13 ± 0,19; 5,79 ± 0,15; 6,05 ± 0,16; 5,72 ± 0,20). On average, 6 acts of drinking were recorded in the studied cows, which corresponds to the temperature readings of the animal. Signs of acidosis of the rumen were noted in cow No. 66,805 (the pH of the contents of the scar is below 6). It was shown that a clinical examination of the animal confirmed this diagnosis. It was established that on November 25 and December 15, the system detected sexual hunting in animal No. 58,928, which was confirmed by the farm staff, the duration of peak activity in both cases is about 12 hours. It was found that cow No. 91,827 (bolus No. 6) had an increased temperature (maximum level 41.1 degrees Celsius), cow No. 58,928 (bolus No. 9) also had an increased temperature of the contents of the rumen (maximum level 39.8 degrees Celsius). After the clinical study, the diagnoses were clinical mastitis (bolus No. 6) and subclinical mastitis (bolus No. 9). (Conclusions) It was stated that the system of internal monitoring of the physiological state can be useful for detecting signs of acidosis of the rumen and mastitis of cows.

Research on Improvement of Light to Moderate Salinization and Alkalinization Farmland in Northeast China

The soil barrier factors currently present in Tuquan County, Northeast China, such as drought, waterlogging, stickiness, salt, alkalinity, and barrenness. This study chose to build a core demonstration area of 50 mu in Xinglongshan Village, Tuquan County. Seven improvement measures were adopted for soil improvement, including straw returning, alkaline amendment, desulfurization gypsum, organic fertilizer, deep tillage and deep loosening, furfural residue, and salt alkali tolerant variety screening. After adopting the above measures, the average soil pH value decreased by 0.4-0.9, the total salt content decreased by more than 10%, and the organic matter increased by more than 0.2 percentage points. The physical and chemical properties of the soil in the experimental area were significantly improved. These measures not only significantly improve the soil fertility of saline alkali farmland and increase the average grain yield by more than 15 percentage points, but also play a role in protecting farmland, thus forming a virtuous cycle.

Current status of stream water quality around selected Tea Gardens from Southern Western Ghats, Tamil Nadu, India – A case study

In this study, metal concentration in tea garden-associated stream water samples from the south Western Ghats of Tamil Nadu was evaluated using ICP-MS to know the current status of pollution level, sources of pollution, probable water quality, and impacts of heavy metals. Stream water pollution of hill regions communities using the heavy metal pollution index, principal compound analysis, and Pearson correlation analysis were measured.

PO4 and F- UV-spectrophotometer, Na, K, and calcium (flame photo meter), NO3- NO3-N (Electronic method-horiba), and turbidity meter to evaluate the stream-water quality were used, and heavy metals, particularly Al, As, Cd, Fe, Cr, Cu, Zn, Pb, Ni, and Mn are analyzed as heavy metal pollutions. The phy-chem average values of pH, Temp, EC, Tds, Salinity, alkalinity, cod, bod, do, chloride, calcium, C. hardness, M. hardness, T. hardness, N-Nitrogen, Phosphate, Potassium, Sodium, Turbidity, Fluoride, Sulphate, and Sulphur are found 8.13, 27.57 °C, 218, 111.67, 78.67, 70.39, 2029, 5.70, 3.83, 70.83, 737, 62.30, 166.11, 679, 1132, 149, 11, 28.33, 4.44, 07, 178, 180 respectively. Heavy metal concentrations, including aluminum, arsenic, cadmium, iron, chromium, copper, zinc, lead, nickel, and manganese, are detected at 32, 7.2, 6.24, 96.4, 0.00, 0.00, 40, 0.00, 0.00, 30 μg/L, respectively. Concentrations of studied heavy metals, particularly, Mn, Ni, Cd, and Fe, have measurements that are greater than the permissible standard limits of BIS, WHO.

Prevalence and health risk evaluations of mycotoxins in drinking water sources in Nigeria.

Mycotoxins in drinking water are neglected pollutants that have serious health implications when ingested. Common mycotoxins with health concerns include deoxynivalenol (DON), ochratoxin A (OTA), and zearalenone (ZEN). This study considers the distribution and apparent health risks of these mycotoxins in drinking water sources (groundwater, surface water, bottled water, sachet water) in three Southwest Nigeria States: Osun, Oyo, and Lagos States, using the UHPLC-ESI-QTOF. ZEN and DON were found in all 95 water samples across all three states. ZEN in sachet water samples has the highest mean concentrations, with those from Osun, Oyo, and Lagos States having concentrations of 14.96 ± 4.46, 8.59 ± 3.86, and 10.56 ± 2.84 μg L-1, respectively. In contrast, the mean concentrations of all three mycotoxins (± Standard Error of Mean) in bottled water samples are the lowest across the three States. The mean concentrations of OTA in sachet water samples (2.93 ± 0.79, 1.24 ± 0.40, and 3.01 ± 1.50 μg L-1) are slightly higher than those in bottled water (1.47 ± 0.28, 1.53 ± 0.31, and 0.75 ± 0.31 μg L-1) for Osun, Oyo, and Lagos States, respectively. Groundwater samples across the three States had the lowest average pH values, below the WHO's lowest limit of 6.5. Principal Component Analysis studies indicate that all three mycotoxins in water samples are closely associated by source. Possible human exposure values for ZEN suggest some health concerns, especially with the use of sachet water type based on the estrogenicity of this mycotoxin. However, OTA values for all water samples analyzed, are much lower than the tolerable daily intake (TDI) of 4.73 μg kg-1 bw per day provided by European Food Safety Auhtority (EFSA). The levels of DON in all water sample types were of no serious health concern. However, human exposure levels to all three mycotoxins in bottled water fall within safe limits of health-based guidance values (HBGV) indicating that this drinking water type is better treated, unlike sachet water. Nevertheless, stakeholders need to re-examine water quality with respect to these mycotoxins and adopt stringent guidelines and new water treatment strategies to provide consumers with safe drinking water in line with the UN SDG #6.

Groundwater Quality Assessment in Iworoko-Ekiti Environs, South-Western Nigeria Using Chemical Indices: Implications for Irrigation and Household Utilities

Groundwater quality of Iworoko-Ekiti and environs for irrigation and domestic purposes has partly been established using chemical indices. Groundwater quality assessment in the area is of great importance because of the influence of various activities in the area. The area is thickly populated by citizens and higher institution students across Nigeria. At the moment, sanitary conditions are very poor as the main occupations are trading and farming. Nineteen hand-dug wells were randomly sampled within the settlement. Flame photometry and spectrometry were used for cations and anions analyses respectively. Average values of pH, EC and TDS are 7.02, 342µS/cm and 230ppm. The average trend of major cations and anions concentrations is Ca2+&gt;Na+&gt;Mg2+&gt;K+ and HCO3-&gt;Cl‑&gt;SO42-&gt;CO32- respectively. Average values of Degree of Contamination and Revelle Index are 14 and 0.6 respectively. SAR, MAR, %Na, KI, TH, CIA-1 and CIA-2 has an average value of 0.7, 37.4, 24.8, 0.3, 162ppm, 0.4 and 0.9 respectively. Based on these values, the water is suitable for irrigation. In general, 31.6% of the hand-dug wells are slightly acidic and 10.5% have Revelle index &gt;1 above recommended values respectively. 10.5% from the hand-dug wells have KI above one, 5.3% has MAR above recommendation making them unfit for irrigation purposes. Hence, majority of the wells are suitable for irrigation with exception of a few wells. However, the elevated Cl- concentrations in all the wells, make them unfit for human consumption. Weathering of migmatite and granite gneisses together with anthropogenic activities really contributed to the chemistry of the groundwater.
