Assessment of Physicochemical Parameters of Water in Puliyanthangal Lake of Ranipet, Tamilnadu, India

The present investigation is centered on the Physicochemical characteristic features in water samples collected from the Puliyanthangal lake of Ranipet region which is suspected to be influenced by the intrusion of tannery effluents and domestic waste by direct and indirect means. Monthly water samples were collected at station 1 and station 2 from the Puliyanthangal lake of Ranipet area for the period of one year from May 2016 to April 2017. The range of physio-chemical parameters such as appearance (turbid/clear), colour (colourless/green), odour (none), total dissolved solids (265-1553), turbidity (0.9 - 13.17 ), electrical conductivity (76-782 Mhc), PH (6.85-7.93), dissolved oxygen (4.73-22.50 ), calcium (46.33-152), magnesium (12.10- 36.33), sodium (211-296), potassium (0.30-24.26), iron (0.02-0.49), manganese (0.01-0.29), free ammonia (0.04-1.14), nitrite (0.01-1.37) nitrate (6-41), sulphate (19.5-234) and phosphate (0.03-3.88) were recorded and discussed. Unit of the chemical parameters is represented as mg/l and physico-chemical parameters were estimated using the standard method of APHA (2005). The data was analyzed using two way ANOVA. However, escalation of physicochemical variables was noticed only in sampling station 1 and this may be due to the entry points to receive the high amount organic load from the discharge of tannery effluents and domestic wastes by direct or indirect means. It is suggested from this study that these biotopes are to be conserved from the intrusion of pollutants so that the biodiversity of the ecosystem would be sustained.

How accurate is the remote sensing based estimate of water physico-chemical parameters in the Danube Delta (Romania)?

The current paper estimated the physico-chemical properties of water in the Danube Delta (Romania), based on Sentinel 2 remote sensing data. Eleven sites from the Danube Delta were sampled in spring and autumn for three years (2018-2020) and 21 water physico-chemical parameters were measured in laboratory. Several families of machine learning algorithms, translated into hundreds of models with different parameterizations for each machine learning algorithm, based on remote sensing data input from Sentinel 2 spectral bands, were employed to find the best models that predicted the values measured in laboratory. This was a novel approach, reflected in the types of selected models that minimised the values of performance metrics for the tested parameters. For alkalinity, calcium, chloride, carbon dioxide, hardness, potassium, sodium, ammonium, dissolved oxygen, sulphates, and suspended matter the results were promising, with an overall percentage bias of the estimates of +/- 10% from the observed values. For copper, magnesium, nitrites, nitrates, turbidity and zinc the estimates were fairly accurate, with percentage biases in the interval +/- 10% - 20%, whereas for detergents, led, and phosphates the percentage bias was higher than 20%. Overall, the results of the current study showed fairly good estimates between remote sensing based estimates and laboratory measured values for most water physico-chemical parameters.

Seasonal Variations of Algae in Relation to the Water Quality at Kingfisher Lake, Central Nepal

Algae can be found in the sea, freshwater and wastewater all around the world. Although the majority is microscopic, some are large. In this study, a total of 44 samples, were collected in two seasons (pre-monsoon and post-monsoon) in the years 2021-2022 from Kingfisher Lake, located in the Bharatpur, Chitwan District. A total of 51 algal species belonging to six classes were recorded. Information on the distribution of algal flora of Kingfisher Lake was collected and the data revealed that the dominant members belong to the classes Bacillariophyceae and Zygnematophyceae, each having 15 species; followed by Chlorophyceae, Cyanophyceae and Euglenophyceae. Similarly, the physico-chemical parameters of water were measured by a digital portable multiparameter (HI98194) in the field. Water temperature was low during post-monsoon season. Electrical conductivity, Total Dissolved Solids (TDS), Oxidation Reduction Potential and Dissolved Oxygen were high in post-monsoon season while the pH of the lake water was alkaline and low pH in post-monsoon season. The number of algal species was found higher in pre-monsoon season than in post-monsoon season. The study showed that the lake is rich in algal species. Presence of the species like Closterium sp. and Oscillatoria sp. indicate that the lake is eutrophicated and polluted. Thus, further investigations were needed.

The feeding ecology of grass carp: A review

AbstractAs an economically important herbivorous fish, the range of grass carp (Ctenopharyngodon idella) has expanded in the world and its ecological influences have become more evident. Currently, we have embarked on assessing the effect of grass carp on aquatic organisms and water quality by integrating the outcomes from previous ecological studies. Bibliographical data integration shows that aquatic plant preference is likely to be related to the cellulose proportion, calcium, sucrose and citric acid of the aquatic plant. Moreover, pharyngeal teeth and multiple gene copies of taste receptors could help reveal the feeding mechanism of grass carp. The expansion of the number of sweet‐detecting T1R2 genes, and the functional potential of Umami taste receptor T1R3 by calcium‐regulation was speculated on the basis of previous experimental observations of grass carp, suggesting that aquatic plant consumption by this species is tightly associated with the taste receptors. Apart from the competition in living space between grass carp and other fish, the effects of consuming zooplankton and zoobenthos were summarized to reveal general passive feeding of grass carp, as well as the feeding choice in the absence of aquatic plants. Water quality data were gleaned to make comparative analyses between groups stocking with and without grass carp to uncover changes in water physicochemical parameters in short‐ (<1 year) and long‐term impacts. This review provides insight into the grass carp feeding behaviour and mechanisms and it will help find a balance between ecological harmony and the industrial development of grass carp.

Physico-Chemical and Bacteriological Analyses for Evaluating the Quality of Municipal Water Supply in Kathmandu District

Water samples from municipal water supplies in Kathmandu District were collected from 10 different sampling spots between April to May, 2018. Analyses of various physico-chemical parameters of water conducted. Physical parameters (pH, electrical conductivity, TDS) and Chemical Parameters like (total alkalinity, total Hardness, calcium, magnesium, chloride, iron, nitrate, and ammonia) were determined. This analysis was undertaken to determine whether water from municipal supply is suitable for drinking purpose or not. It indicates that in some places the municipal supplies in Kathmandu district are not suitable for drinking without filtration and proper purification.

Also there was no mortality in the control (0.00mg/l) setup while mortality increased with increased the control (0.00) setup, while mortality increased with increase in concentration. The LC50 value of Vestaline was determined to be 113.56mg/l. Results of the physico-chemical parameters of water exposed to acute concentrations decreased significantly (p<0.05) with increase in concentration for dissolved oxygen and increased in pH, Total dissolved solids (TDS) and Electrical conductivity(EC) while Temperature showed no significant difference (p>0.05 ). Vestaline (Pendimethalin) herbicide from this study is toxic on Clarias gariepinus juveniles and should be used with care.

Phytochemical Characteristics of Various Dimsum Fortified with Purslane Leaves

(One of the villages with abundant natural resources is Wonosalam Village in Jombang, East Java. One of the potentials is purslane (Portulaca oleracea) but underutilized yet and just known as a wild plant or weed. The availability of pursiane plants reaches 5-8 quintals/month from each population plot. However, this plant will be discarded because it interferes with the growth of economically valuable plants. Whereas according to research, purslane plants contain lots of phenolic bioactive compounds, flavonoids, carotenoids, and essential fatty acids that are useful as antioxidants and disease prevention. Therefore, this experiment aimed to obtain the best composition of various processed dimsum fortified using purslane leaves. This study used a randomized block design with various formulations of dimsum fortified using purslane leaves, namely purslane dumpling (SK), fantasy purslane dumpling (SKF), purslane drew-dumpling (DK) and purslane manti (KM) the results showed that pursiane dumplings were the best treatment, with physico-chemical parameters of protein, fat, water, ash, and carbohydrate content of 14.10%; 5.4%; 50.54%; 2.37%; and 21.8%. All kinds of dimsum fortified with purslane leaves contain unsaturated fatty acids from the medium-chain fatty acid (MCFAs) and polyunsaturated fatty acids (PUFAs) group.

Surveillance of Legionella pneumophila: Detection in Public Swimming Pool Environment.

The bacterium Legionella pneumophila is a ubiquitous microorganism naturally present in water environments. The actual presence of this opportunistic premise plumbing pathogen in recreational swimming pools and hot tubs in the northwestern part of Croatia has not been investigated. This study aimed to analyze the presence of the opportunistic pathogen L. pneumophila in public swimming pool water in Primorje-Gorski Kotar County (N = 4587) over a four-year period (2018-2021). Additionally, the second aim was to investigate the connection between the presence of L. pneumophila and pool water physicochemical parameters using mathematical predictive models. The presence of L. pneumophila was detected in six pool samples. Five positive samples were found in the water of indoor hot tubs filled with fresh water, and one positive sample in an outdoor recreational saltwater pool. A predictive mathematical model showed the simultaneous influence of chemical parameters dominated by the temperature in saltwater and freshwater pools, as well as the significant influence of free residual chlorine and trihalomethanes. Our results pointed out that keeping all physicochemical parameters in perfect harmony is necessary to reach the best disinfection procedure and to avoid the optimum conditions for L. pneumophila occurrence.

Water Quality Index Application to Evaluate the Ground Water Quality in Kalar City- Kurdistan Region- Iraq

The study is aimed to identify and classify the quality of ground water in Kalar city- Kurdistan region- Iraq through a single number that achieves by water quality index (WQI). Weight arithmetic water quality index (WAWQI) was used to assess 14 physicochemical water parameters such as turbidity, pH, total dissolved solids (TDS), total hardness (TH), total alkaline (TA), electric conductivity (EC), dissolved oxygen (DO), sodium (Na+), calcium (Ca2+), magnesium (Mg2+), sulfate (SO4 2−), chloride (Cl−), nitrate (NO3 −) and potassium (K+). Ground water samples were taken from 5 stations in different locations in Kalar city during the period of March and April 2021. In addition, 20 samples were taken for 5 stations in total, 4 samples for each station, 2 samples in March and 2 in April, the interval period for taking samples was 2 weeks. Water quality indices of stations 1, 2, 3 are 53.10, 51.95 and 51.08 respectively, they are in poor quality range, thus the water quality of these station is moderately polluted, while water quality indices of stations 4 and 5 are 42.23 and 44.66 respectively, which are in good quality range. The study concluded that the ground water in kalar city is slightly to moderately polluted. Calcium and magnesium contaminants in Kalar ground water are high and must be decreased into safe range. TDS, TH, DO, pH and turbidity values are in allowable ranges in all 5 stations, but they are critical and need treatment to get an excellent water quality.

Assessing the effect of sunlight exposure on physicochemical properties of bottled water in Addis Ababa, Ethiopia: An experimental observational study

Bottled water is potable water that is manufactured, distributed, or offered for sale and intended for human consumption. However, bottled water retailers usually expose bottled water to direct sunlight at the point of sale, and store it for extended periods. Therefore, this study aimed to investigate the effects of sunlight exposure and storage time on the physicochemical properties of bottled water. An experimental observational study design was employed to assess the effect of direct sunlight exposure on selected physicochemical parameters in four water brands (40 samples for both control and exposed) for 28 days in Addis Ababa, Ethiopia. The study's average sunlight intensity and sunshine hours from 3 October to 30/2020 were 197.7 ± 31.8 W/M2 and 7. 3 ± 2. 7 h, respectively. The mean values of the physicochemical parameters of bottled water before and after exposure to sunlight were compared using a paired sample t-test and Wilcoxon signed-rank test with a significance level of 0.05. Approximately 80% of the analysed parameters did not match the labelled value of bottled water. This study showed that the values of pH, F-, and NO3− were decreased from 7.31 to 7.02; 0.20 to 0.15 mg/L, and 3.95 to 3.52 mg/L, respectively. Whereas the level of NO2−, TDS, and turbidity was increased with increasing sunlight exposure from 0.00 to 0.02 mg/L, 82.82 to 85.24 mg/L, and 0.00 to 0.57 NTU, respectively. Statistically significant differences in pH, F−, NO2−, and turbidity levels were found between the exposed and non-exposed groups of bottled water. Apart from the increase or decrease in chemical concentration after sunlight exposure, the physicochemical parameters of the exposed bottled waters were within the recommended standards, except for fluoride and turbidity. However, the fluoride concentration was below the recommended level in both exposed and unexposed samples, with a further reduction in sunlight-exposed bottled water samples. Therefore, regulators should ensure that bottled water is protected against long-term direct exposure to sunlight to provide safe water to consumers.

Assessment of pollution variability across the central part of the Büyük Menderes River (Turkey) using water physicochemical parameters and biomarker responses in the non-biting midge Chironomus riparius (Diptera: Chironomidae)

ABSTRACT This study aimed to examine the pollution level in the central part of the Büyük Menderes River (in both the main tributary and Çürüksu stream) in Denizli (Turkey) using water physicochemical parameters and biomarker responses in Chironomus riparius (Diptera: Chironomidae). In physicochemical parameter evaluations, Sığma, Korucuk, and Güzelköy stations were determined to have higher mean temperature, pH, salinity, conductivity, and total dissolved solids (TDS) values and lower dissolved oxygen (dO2) and saturated oxygen (sO2) values than Bekilli, Mahmutlu, and Sarayköy stations. In biomarker response evaluations, C. riparius larvae from Sarayköy, Sığma, Korucuk, and Güzelköy stations were found to exhibit inhibited acetylcholinesterase (AChE) activities (55%−68%) and elevated 7-ethoxyresorufin O-deethylase (EROD) activities (191%−281%), glutathione S-transferase (GST) activities (138%−187%), and metallothionein (MT) contents (155%−231%) when compared with the control values. This study proves that different stations are exposed to different pollution sources, the pollution level of a station varies depending on the season, and the stations on Çürüksu stream, among which Güzelköy appears to be the most contaminated, are exposed to more pollutants than those on the main tributary of the river.

Evaluation of heavy metals in water and sediments, pollution, and risk indices of Naltar Lakes, Pakistan.

This study examined the physicochemical parameters of water and sediments in the Naltar Lakes, northernPakistan. Water and sediments were sampled and analyzed for physicochemical parameters. Heavy metals such as iron (Fe, 11% and 12%), nickel (Ni, 100% and 88%), chromium (Cr, 22% and 12%), and arsenic (As, 0% and 12%) of sampling sites had surpassed the threshold of drinking water set by world health organization (WHO) in the Naltar Lake I (Naltar I) and Naltar Lake II (Naltar II), respectively. Water quality parameters were evaluated for the drinking and irrigation water quality indices (WQI). Drinking WQI values were found within the excellent category for Naltar I and Naltar II, except for the 6% of sampling sites observed in the good category. Toxic parameter concentrations were used for the risk indices, which revealed the highest average daily dose(ADD) values of 138 µg/kg-day and hazard quotient(HQ) 1.8 for children through nitrate(NO3) and As consumption in drinking water from the Naltar I and Naltar II, respectively. Water of the Naltar Lakes were characterized by rock weathering dominance.Heavy metal concentrations of sediments showed a moderate level of contamination that poses a low risk to the Naltar Lake ecosystem.

Physicochemical parameters of water in earthen ponds and concrete water storage reservoirs in Bakolori irrigation project, Zamfara state, north western Nigeria

Physicochemical Parameters of large Earthen Ponds and Concrete water storage reservoirs (CWSRs) of Bakolori Irrigation Project (BIP) were investigated from March 2019 to February 2020. Four sampling stations were randomly selected from the two water body types. Air and Water Temperature, Dissolved Oxygen (DO), pH, Electrical Conductivity (EC), Water Depth, Total Dissolved Solids (TDS), Transparency & Salinity were determined in situ, while water samples were collected monthly from the eight sampling stations and taken to the laboratory for analysis of Alkalinity, Hardness, Nitrate-N and Phosphate-P. The data collected were arranged on the bases of two seasons (dry & wet) and five sub-seasons, namely: Early dry (Oct - Dec); mid dry (Jan & Feb); late dry (March - May); Early rainy (June & July) and flood period (Aug & Sept), and subjected to T test analysis using Minitab statistical package. Results were compared with the water quality standards for Human consumption, aquatic life and fish production aquatic life and aquaculture. Results showed that with the exception of high Turbidity (low transparency) due to mud & debris in the water storage reservoir in some sub seasons, the water bodies were suitable for Aquatic life and Aquaculture. But partly unsafe for human consumption. The study recommends continuous assessment of the water bodies for physicochemical parameters. It further recommends the use of several water storage reservoirs for mudfish (such as Clarias and Hetrobranchus species) production instead of leaving them redundant as observed during the study period.

Study of characteristics of water and fish production in Umrar Dam of Umaria District (M.P.) India

Present study were carried out for physico-chemical parameters of water Umrar dam of Umaria district, Madhya Pradesh, India. The aim of the study was to establish the safety of water and fishes from the Lake. Different physico-chemical parameters such as pH, Electrical Conductivity (EC), Dissolved Oxygen (DO), Total Alkalinity (TA), Total Hardness (TH), Chloride (Cl), Nitrates (NO3), Phosphate (PO4), Turbidity and Total Dissolved Solids (TDS) of lake water were investigated during pre-monsoon, monsoon and post-monsoon period. The results on physico-chemical parameters of water and clearly indicate highly productive nature of the Umrar dam. The water quality parameters showed maximum values during pre-monsoon compared to rainy and winter seasons. It was inferred from the results of water quality and soil analysis that Umrar dam was productive in nature.

Identification of scale drop disease virus based on environment DNA in an aquaculture facility of Singapore

Scale drop disease virus (SDDV) is an emerging virus in Asian countries that infects barramundi, resulting in huge economic losses in aquaculture industries. Current methods of diagnosing viral diseases in aquaculture are time-consuming and rely on infected sick fish to confirm results. Delays in the management of outbreaks often occur due to the inefficiencies of conventional pathogen detection methods and difficulty in visually inspecting animals in aquaculture facilities. Environment DNA (eDNA) approaches on the other hand investigate the provenance of the genetic material in the environment, thus allowing the detection of specific pathogens even before animals become infected. SDDV was recently detected in the mucus and fin clips of infected fish, therefore it presents itself as an ideal viral candidate pathogen to test the viability of eDNA as an early monitoring tool for its detection and quantification from water samples. This study aimed to test for the first time, the viability of detecting SDDV using eDNA approach in an aquaculture research facility in Singapore with past reports of SDDV infected barramundi. Quantitative PCR (qPCR) and digital droplet PCR (ddPCR) targeting SDDV in water samples from several tanks over a period of 6 months were conducted to understand the association of abiotic and biotic variables with SDDV abundance. Both PCR techniques detected SDDV eDNA, with ddPCR outperforming qPCR as it was more sensitive for low virus copy numbers. SDDV was also detected in fingerling fin clips from tanks where higher levels of its genome were found. SDDV abundance was significantly associated with periods of higher rainfall and lower salinity (p < 0.05). Although SDDV abundance was more strongly associated to these cooler periods, temperature itself was not significantly associated with SDDV (p > 0.05). These findings demonstrated ddPCR as a more efficient technique to detect low levels of SDDV in aquatic environments. The eDNA approach offers an innovative way to identify viral diseases in aquaculture as generally very few options are available for farmers to pre-empt outbreaks. It also warrants future studies to better understand SDDV dynamics throughout the year and its association with the water physicochemical parameters and host microbiome.

Dissemination of antibiotic resistance in antibiotic-free recirculating aquaculture systems

Currently the demand for antibiotic free aquaculture has increased, but to which extend AMR spreads in aquaculture in the absence of antibiotic additives remains to be elucidated. Therefore, we aimed to reveal potential factors that affect AMR in antibiotic free aquaculture systems. As a model system, we utilized enclosed recirculating aquaculture containing African catfish (Clarias gariepinus). We sampled water and biofilms during various rearing periods and performed 16S ribosomal RNA (rRNA) high-throughput sequencing and qPCR for six antibiotic resistance genes (ARGs), the class 1 integron integrase gene intI1 and the 16S rRNA gene. In parallel, we monitored the physicochemical water parameters during the duration of aquaculture application. During the rearing operation nitrogen compounds accumulated to 42.00 ± 18.17 mg/L ammonium, 153.0 ± 7.5 mg/L nitrate and 2.9 ± 0.9 mg/L nitrite. However, this did not influence the dominant bacterial communities or ARG abundance in either biofilm or aquatic samples. Despite the absence of antibiotic use, ARGs consistently occurred in high relative abundance, but at constant levels (e.g. sul1: −2.0 ± 1.5 log10 copies/16S rRNA) during rearing. Moreover, one ARG, the β-lactamase gene blaTEM was significantly associated with the bacterial biofilm lifestyle. Its abundance further correlated with the taxonomic composition and α-diversity of the microbial communities. In conclusion, ARGs, were present in high relative abundance, but remained stable during the period of recirculating aquaculture. Consequently, bacterial communities were able to retain high ARG abundance during aquaculture operations, despite the absence of selective pressures.

This study aims to determine the possibility of cultivating Eucheuma cottonii-type seaweed based on the study of physico-chemical parameters of water and soil around Pancana Beach, Barru Regency, Indonesia. The research was carried out for 2 months, from July to August 2022, by conducting four sampling times for the study of cultivation aspects, including physico-chemical water and soil parameters. Determination of research locations based on differences in environmental characteristics at each research location. Station (ST) A is located on a small river around Butung-Pancana, Station (ST) B is located around residential areas, and Station (ST) C is located around the estuary of Pancana. The data collected consisted of water physico-chemical parameter data, namely water temperature, salinity, water pH, water dissolved oxygen, phosphorus (PO4), and N-Total water. On the other hand, the soil parameters include the value of soil pH and soil texture. The data obtained were then collected, processed, and analyzed by descriptive analysis.The results showed that the value of the water physico-chemical parameters in the research location, namely around Pancana Beach, Barru Regency, Indonesia, which consisted of water temperatures in the range of 28.1-28.9, dissolved oxygen 4.18-6.01 ppm, water pH in the range of 6.3-7, salinity 31.33-32.33 ppt and PO4 and N-Total at the beginning and end of the study, were in the appropriate range, while the pH value of the soil is in the range of 7.82-8.01 and the soil texture is a sandy texture. Thus, it can be stated that the waters of Pancana Beach, Barru Regency are still suitable for the cultivation of Eucheuma cottoniii seaweed based on the physico-chemical parameters of water and soil.

Plankton dynamics of Kanke reservoir (Jharkhand, India) in relation to physico-chemical parameters of water

A study was conducted on plankton dynamics of Kanke reservoir in relation to selected physico chemicalparameters from 10 September 2020 to 10 July 2021. Total ten sampling stations were chosen based onwater characteristics. Overall water quality parameters (Temperature, DO, CO2, TH, TA, Nitrate, Phosphateand pH) were found in the limits suggested for aquaculture practices except few station like STN 1, 4, and5 shown poor water quality, this may be due to domestic sewage and organic matter load released fromlocal communities. In the present study, total 50 genera of phytoplankton were identified. Of which 24genera of Chlorophyceae, 12 genera of Bacillariophyceae, 11 genera of Cyanophyceae, 2 genera ofEuglenophyceae and 1 genera of Dinophyceae. The phytoplankton abundance shows sharp increase fromJanuary to April (pre-monsoon) with Chlorophyceae as the most dominant group and Euglenophyceae asthe least dominant. Similarly, total 13 genera of zooplankton were identified. It included 6 genera of Rotifers,4 genera of Cladocerans and 3 genera of Copepods. A positive correlation was noticed between temperatureand phytoplankton in the Kanke reservoir. All group of zooplankton showed very lowabundance duringmonsoon, however, there was an increase in abundance during pre-monsoon, and highestabundance value was recorded during post-monsoon months. Findings of the present study shows that the waterquality of Kanke reservoir is still safe for aquaculture practices except few stations. But the sign ofdeteriorating water quality is started to appear as algal scam/bloom formation. The findings of this studywill serve as a baseline data for further investigations, comparing the future changes in this reservoir andto conserve this ecosystem.
