Can the variation of physical and biological parameters explain the distinct sessile communities from cryptic habitats across a coastal bay?

Coastal habitats are critical transition zones supporting a diverse and abundant marine community but are under strong human influence. Sustainable management of those habitats must rely on robust understanding of the processes regulating the diversity and functioning of the local communities. However, most of the studies to date have focused predominantly on the benthic communities from positive surface of rocks. Here, using a sessile community from negative surfaces, we described how larval availability, recruitment, predation and physical parameters affect the diversity and distribution of species along a gradient formed from the mouth to the middle portions of a diverse coastal bay threatened by the expansion of a port in the Southwestern Atlantic Ocean. Monthly, from August 2015 to November 2016, we compared the composition of sessile species on the lateral and undersurface of rocks, the water physical parameters, the substrate composition and availability, as well as the abundance of larvae in the plankton and the recruitment in the mouth and the middle portions of the bay. Additionally, we also conducted a predator exclusion experiment to compare the predation pressure across the bay. The sessile community in the middle of the bay is a subset of the community in the mouth, where ascidians and bryozoans contributed to increase diversity. While the amount of rocky substrate was similar between sites, the proportion of granite, the water turbidity and the chlorophyll concentration were higher in the middle of the bay. Larvae and recruits were more abundant in the middle of the bay, mainly during the spring and summer months, but recruits were more diverse in the mouth of the bay during the whole study. Although reducing diversity, predation had similar effects in the two sites and did not explain the differences in the sessile communities. Our results reinforce that in critical transition zones, the relative importance of regional oceanic and local processes changes along the ocean-land gradient. While communities in the mouth of the bay are more diverse and dynamic, being composed by several species of colonial filter-feeding organisms, the high turbidity in the middle of the bay seems to restrict those organisms, resulting in communities mainly composed by serpulid worms and oysters. Communities closer to the bottom of the bay are also near to the source of allochthonous sediments and nutrients, being consequently more susceptible to human disturbances.

Development of Water Quality Monitoring Device Using Arduino UNO

Regular water quality monitoring of water bodies is essential to ensure it is within the allowing standard limits. The development of a simple and low-cost water quality measurement device for real time monitoring using Internet of Things (IoT) technology is presented in this study. Kolora meter is an alternative to the existing commercial monitoring devices. It was developed using the open-source platform Arduino UNO model and NodeMCU board as the microcontroller and Wi-Fi connection respectively. Two sensors such as temperature and turbidity were selected to be installed in the early stage of Kolora meter development. The physical parameters (temperature and turbidity) of water were measured and the measured data collected are able to be viewed and monitored on the mobile phone using Kolora Mobile Application via Wi-Fi connection. Therefore, this surface water quality device has potential to be applied in real time monitoring for early pollution detection and during COVID-19 pandemic spread due to limited movement.

Keterkaitan Hubungan Parameter Kualitas Air Pada Budidaya Intensif Udang Putih (Litopenaeus vannamei)

Water quality parameters play an important role in intensive pond ecosystems. The purpose of this study was to determine the relationship between of water quality parameters in intensive shrimp farming of L. vannamei. This research was carried out for 95 days of intensive shrimp farming in PT. Menjangan Mas Nusantara Company, Banten, with the physical, chemical, and microbiological parameters of water as the main reference object of observation. The results showed that during the shrimp culture period the pond water quality parameter concentration was considered to be quite optimal with a stable fluctuation trend, except for the salinity and TOM parameters whose values ​​were above the water quality standard. Correlation test results state that between the physical chemical parameters have a strong and heterogeneous relationship, with the strongest parameters of pH, phosphate, nitrite, and TOM. As for the microbiological variables, the correlation of physical chemistry parameters of water is considered to be very weak, because from the correlation test results, only DO parameters showed the correlation with microbiological parameters. The conclusion of this study, that during intensive shrimp culture period, the physical and chemical parameters of water have a strong correlation of association between one another and the highest are pH, phosphate, nitrite, and TOM, but only dissolved oxygen parameters that show the relationship correlation with microbiological parameters.

Simulation and Experimental Studies on the Influencing Factors of a Thermal Flowmeter with Constant Temperature Difference

Due to the fact that the thermal flowmeter with constant temperature difference brings large errors when measuring downhole flow in low flow-rate, the influence of temperature and pressure was studied. According to the relationship between the electric power of the flowmeter heater and the measured flow rate, the influence of temperature on the physical parameters of liquid water was analyzed, and the change curve of the heat transfer power of the flowmeter and flow rate at different temperatures was simulated numerically. An experimental platform with adjustable water temperature and flow rate was built on that basis, and the relationship between the power of the flowmeter and flow rate at 25–40 °C under constant pressure was thereby analyzed, revealing that power of the flowmeter heater increases monotonically with temperature. In terms of theoretical analysis, a 500 m increase in the well depth leads to an error of 2.2 m3/d when the flowmeter is in the depth from 0 to 2 000 m; while the error is 0.6 m3/d when it is in the depth from 2 000 to 4 000 m. The results showed that output power of the thermal flowmeter with constant temperature difference will increase with the increase of well depth (wellbore temperature, pressure change), resulting in measurement errors, which provides a theoretical basis for the correction and effective application of the flowmeter measurement results.

Superposition learning-based model for prediction of E.coli in groundwater using physico-chemical water quality parameters

The prediction of waterborne bacteria is crucial to prevent health risks. Therefore, there is a need to study the quality of groundwater by predicting the presence of E.coli. The experimental data for prediction is obtained from BITS-UVA (University of Virginia) groundwater contamination project, having 1301 experimental laboratory results that will be synthesized to test the physical, chemical, and microbiological parameters of water. In this study, a superposition-based learning algorithm (SLA) is proposed to observe the patterns of ANN-based sensitivity analysis to determine the importance of each water quality parameter resulting in the prediction of E.coli in groundwater. Mean Square Error (MSE) and the Coefficient of determination (R2) are calculated using MATLAB (R2019b, Mathworks, Natik, MA, USA) software for model performance evaluation. The highest correlation is observed between E.coli and the pH values, whereas the lowest correlation is observed with Dissolved Oxygen. In order to find out the uncertainty in the output of our mathematical model, a sensitivity analysis for the seven models is carried out. The results show that the model having Turbidity, pH, Total Dissolved Salts (TDS), and Electrical Conductivity as inputs displayed the best performance. The model architecture constitutes three hidden layers, twenty neurons in each layer, which is optimized using the Bayesian Regularization training algorithm (BR) with the overall highest R2 values of 0.90 and lowest MSE values of 0.0892. Patterns of the trained neural network are presented in superposition. After training, it can be concluded that the superposition models based on Grover's algorithm is more efficient in predicting all patterns in the counts of E.coli in groundwater. The algorithm is superimposed on multiple neural network architectures and returns a trained neural network. In addition to accurate results, there is also a need to automate the process of real-time bacterial monitoring for minimizing the error.

Researches of technological mode of operation of gas wells with a single-lift elevator at a critical speed of upper flow

The article discusses the modes of movement of gas-liquid flows in relation to the operating conditions of waterlogged gas wells at a late stage of field development. Algorithms have been developed for calculating gas well operation modes based on experimental work under conditions that reproduce the actual operating conditions of flooded wells of Cenomanian gas deposits. The concept of calculating the technological mode of operation of gas wells with a single-row elevator according to the critical velocity of the upward flow is considered based on the study of the equilibrium conditions of two oppositely directed forces: the gravity of water drops directed downward and the lifting force moving water drops with a gas flow directed upward. A calculation was made according to the method of the averaged physical parameters of formation water and natural gas in the conditions of flooded Cenomanian gas wells in Western Siberia. The results of a study of the dependence of the critical flow rate of Cenomanian wells on bottomhole pressure and diameter of elevator pipes are presented.

Geochemical Variability of Surface Sediment in Post-Mining Lakes Located in the Muskau Arch (Poland) and Its Relation to Water Chemistry

Water and sediment chemical compositions were investigated in 75 post-mining lakes in the eastern part of the Muskau Arch region (Western Poland, Central Europe). The lakes, originating from lignite and clay surfaces and underground mining activity, exhibited a wide gradient of physical and chemical water parameters. The most pronounced variability in water parameters was observed in pH values, conductivity, and oxygen concentration in the mixolimnion and monimolimnion. In addition, the lakes varied in terms of their trophic status, indicated by their dissolved organic carbon (DOC) and phosphorous concentrations. In general, lakes with higher pH values had higher trophic states, and some even exhibited hypertrophic conditions. The Monte Carlo test indicated that the water pH, phosphorus, DOC, and silicon concentrations could significantly explain the chemical characteristics of sediments.

Assessment of the impact of land use in an agricultural catchment area on water quality of lowland rivers

In several countries around the world, agricultural land area exceeds 70% (Uruguay 82.6%, Kazakhstan 80.4%, Turkmenistan 72.0%, Great Britain 71.7%, Ukraine 71.6% and others). This poses a serious risk of dissipating nitrates into the aquatic environment in agricultural catchments. The aim of this study was to assess the impact of land use on water quality parameters in an agricultural catchment area. It was decided to select for analysis the catchment of the Orla River (river length of 88 km, catchment area of 1,546 km2). The catchment area is predominantly agricultural in character and its entire area has been declared as an agricultural nitrate vulnerable zone (NVZ). A total of 27 survey sites were selected on the main watercourse and its tributaries. Analyses were conducted in the years 2010–2012 to determine physical and chemical parameters of water (pH reaction, conductivity, dissolved oxygen, total nitrogen, organic nitrogen, ammonia nitrogen, nitrates, total and reactive phosphorus) as well as six macrophyte metrics of ecological status assessment (MIR, IBMR, RMNI, MTR, TIM, RI). The average values of most physico-chemical parameters of water quality repeatedly exceeded limits of good ecological status, both in the Orla River and its tributaries. As many as 18 survey sites were classified as moderate ecological status, five sites as poor and only four as good ecological status. The results indicate the impact of land use in the catchment on water conductivity. Differences were observed in the concentrations of biotic components in the main watercourse and its tributaries, and in water quality in the southern part of the catchment in relation to the rest of the study area. This is probably connected with a greater share of forests and surface waters in that area.

STUDY OF WATER PHYSICS, CHEMISTRY, AND BIOLOGY QUALITY IN SWAMP WATER HIGH TIDE CONDITIONS IN BANYUASIN REGENCY, SOUTH SUMATERA

This study was conducted in tidal lowland at Banyu Urip Village, Tanjung Lago District, Banyuasin Region, South Sumatera. Samples were collected two times. The water sample was collected during high tide in primary, secondary, and tertiary canals. The result showed the seasonal variation of physical and chemical water parameters such as temperature 27 – 30 ºC, pH 3 – 5, DO 3.7 – 4.5 mg/l, phosphate 0.01 – 0.02 mg/l, TSS 108 – 232 mg/l, and EC 11 – 107 µmhos/cm. This study also identified 10 classes and 10 genera of phytoplankton. It has potential as a natural food source. The result revealed that physical and chemical water quality parameters were still suitable for aquaculture based on Government regulation of Republic Indonesia number 82 year 2001 about water criteria class III for fisheries. Meanwhile, the great challenge of tidal lowland for fishery management is low pH. Therefore, pre-treatment to increase pH before fish rearing is required.

How Climate Change and Land Use/Land Cover Change Affect Domestic Water Vulnerability in Yangambi Watersheds (D. R. Congo)

In the tropics, the domestic water supply depends principally on ecosystem services, including the regulation and purification of water by humid, dense tropical forests. The Yangambi Biosphere Reserve (YBR) landscape is situated within such forests in the Democratic Republic of Congo (DRC). Surprisingly, given its proximity to the Congo River, the YBR is confronted with water issues. As part of its ecosystem function, the landscape is expected to reduce deterioration of water quality. However, environmental consequences are increasing due to conversion of its dense forest into other types of land use/land cover (LULC) in response to human activities. It is therefore important to check how the physicochemical quality parameters of water resources are influenced by landscape parameters—and to know if the population can adapt to this water vulnerability. To do this, we analyzed the watershed typology (including morphometric and LULC characteristics) and the physical and chemical parameters of water within the principal watershed’s rivers. We also analyzed data from surveys and the Yangambi meteorological station. We found that some landscape indices related to LULC significantly influence water quality deterioration in Yangambi. On average, each person in the Yangambi landscape uses 29–43 liters of water per day. Unfortunately, this falls short of World Health Organization standards regarding some parameters. The best fitted simple linear regression model explains the variation in pH as a function of edge density of perturbed forest, edge density of crop land and patch density of dense forest up to 94%, 92% and 90%, respectively. While many researchers have identified the consequences of climate change and human activities on these water resources, the population is not well-equipped to deal with them. These results suggest that water management policies should consider the specificities of the Yangambi landscape in order to develop better mitigation strategies for a rational management of water resources in the YBR in the context of climate change.

Experimental Studies on Physicochemical Parameters of Water Samples before and after Treatment with a Cold Atmospheric Plasma Jet and its Optical Characterization

Cold plasma-liquid interaction becomes a growing interdisciplinary area of research involving plasma physics, fluid science, and chemistry. Plasma-liquid interaction has gained more interest over the last many years due to its potential applications in different fields. Cold atmospheric plasma jet is an emerging technology for surface drinking water treatment to improve quality and surface modification that is chemical-free and eco-friendly. Cold plasma treatment of water samples results in changes in turbidity, pH, and conductivity and in the formation of reactive oxygen and nitrogen species (RONS). As a result, plasma-activated water has a different chemical composition than water and can serve as an alternative technique for microbial disinfection. CAPJ has been generated by a high voltage 5 kV and a high frequency 19.56 kHz power supply. The discharge has been characterized by an optical method. To characterize the cold atmospheric pressure argon plasma jet, discharge plume temperature, and electron rotational and vibrational temperature have been determined. Cold atmospheric argon plasma jet produced at atmospheric condition contains high energetic electrons, ions, UV radiation, reactive oxygen, and nitrogen species named as cold plasma which has a wide range of applications in the biomedical industry, as well as in water treatment. Nowadays, researches have been carried out on ozonation through plasma jet interaction with surface drinking water. In this paper, we compare the change in physical and chemical parameters of surface water used for drinking purposes. The significant change in the physical parameters such as pH, turbidity, and electrical conductivity was studied. In addition, the significant changes in the concentration and absorbance of nitrate, ferrous, and chromium ions with respect to treatment time were studied. Our results showed that plasma jet interaction with surface drinking water samples can be useful for the improvement of water quality and an indicator for which reactive species play an important role in plasma sterilization.

Assessment of Ground water Quality in Mumbuni Estate, Machakos Town, Kenya

The rapid increase of global human population has led to more people living in towns and cities in the recent past. This has brought pressure on water service provision and sanitation infrastructure in many cities and towns including Machakos town. Due to surface water shortages, groundwater has been an alternative. This includes sinking of boreholes and hand dug shall wells. This study evaluated the concentration levels of physical and chemical parameters of water in selected boreholes and shallow wells in Mumbuni estate, Machakos town. A total of three boreholes and three shallow wells were included in the study. Water samples were collected in triplicates after every two weeks for a period of one and a half months from the selected sampling sites. The samples were transported to the Water Resources Authority (WRA) central laboratory in Nairobi for analysis using the standard methods for the examination of ground water. Independent T-test was used to analyze data and significance levels accepted at p≤0.05. The results obtained were compared with both the World Health Organization (WHO) and Kenya Bureau of Standards (KEBS) drinking water standards in order to determine the quality of ground water and its suitability for drinking. All the parameters measured varied significantly between borehole water and shallow well water except for Calcium, Magnesium and potassium (p≥0.05). pH, turbidity, electrical conductivity, Chloride, Fluoride and Sulphates were within the WHO and KEBS recommended limits for drinking water. Other parameters tested such as Calcium, Magnesium and Potassium were also within acceptable limits. The study concluded that water from boreholes and shallow wells in Mumbuni estate is suitable for drinking.

Natural minerals impact on physical and chemical parameters of potable water

The article presents the research results dealing with the influence of such natural minerals as flint and shungite in relation to the following water parameters pH, TDS, conductivity, cations (NH4+, K+, Na+, Mg2+, Sr2+, Ba2+, Ca2+) and anions (Cl−, SO42−, NO3−, F−, СО32−). It was found that crushed flint and shungite added to the water more significantly increases water hydrogen index if compared to sedimentation. Simultaneously total water mineralization decreases (causing electric 28,4 al conductivity decrease). Considerable decrease in calcium ions concentration (by 36.0 %) was detected in the water infused with shungite and by 20.5% in the water infused with flint. Considerable increase in K+ ions concentration in water infused with flint (46.3%) was revealed. As for the anions F− concentration decreased for both minerals - shungite and flint. These natural minerals are recommended for the treatment of tap water characterized with the increased hardness and excessive fluoride ions content.

We believe that the content and problems in the focus of the research are topical and present significant interest to all those who deal with environmental issues.

Influence of environmental conditions on the mercury levels of the sediment along the Balbina Reservoir, Brazilian Amazon.

Mercury dynamics in hydroelectric reservoirs have been studied worldwide. In tropical reservoirs, especially in those of the Amazon, the influence of geochemistry on Hg levels along this aquatic system is not well understood. The main objective of the present study was to assess the influence of environmental conditions (physical and chemical water parameters, trace element concentrations of sediment and sediment geochemistry) on mercury levels of sediment along the Balbina Reservoir (Amazon basin, Brazil). Sediment was collected along the reservoir and in the main tributaries in May 2015 (n= 10). These samples were assessed for labile iron (LFe), manganese (LMn), aluminum (LAl) and mercury (LHg) concentrations, total mercury (THg) concentrations, organic matter (OM) content, and granulometry. Concentrations in the sediment were 4-212 (LFe), 2-460 (LAl), 180-613 (LMn), < detection limit-256 (LHg), and 12-307μgkg-1 dry weight (THg). In general, these concentrations decreased along the reservoir from upstream to downstream, reaching the lowest concentrations in the middle of the lake, and they increased in the sampling points near the dam. The lability and concentrations of mercury were influenced by the concentrations of LFe, LMn, LAl, and the granulometry and OM content of the sediment. Altogether, THg concentrations of sediments of the Balbina Reservoir encompass the range of concentrations of other reservoirs or natural lakes in the Amazon basin (from ten to a few hundred μg kg-1 dry weight).

In relation to CFU / ml, all mean values were much higher than the maximum established by legislation (500 CFU / ml). It was verified a statistically significant difference was found in the external cistern and tap when compared to the chair tank and triple syringe (p &lt; 0.05). All pH samples were within the standards. Conclusion: The global analysis showed that 100% of the samples were inadequate, which classified the water potability as nonstandard in regard to the current Brazilian legislation.

Analisis Kualitas Air Sungai Hasil Penyaringan Filter Berbasis Arang Sekam

Industrial waste pollution from the upstream of the Bengawan Solo river, makes the river's quality unfit for various purposes. Water filtering needs to be done first to improve its quality. One of them is the absorption process. One of the adsorbents that have good prospects is rice husk waste because of its ability to bind the adsorbate components. Study related to the effectiveness of rice husk charcoal as a water filter material need to be carried out before it can be used as a water filter material. Making appropriate filter technology needs to be done to apply it. The results of the analysis show that the filter can improve the physical parameters of water, namely reducing the residue by 25% on average. Meanwhile, from inorganic chemical parameters, only DO (Dissolved Oxygen) elements have decreased in quality standards. The organic chemical parameters, namely the phenol content are relatively constant, this indicates that rice husk charcoal is not effective in binding phenols. Based on Government Regulation No. 82 of 2001, the filtered water is classified as Class I. However, in its use, other parameters that have not been studied should be studied, namely microbiology, other organic chemistry, radioactivity, etc.The technological capacity needs to be increased by the use of a larger body and or a reduction in the thickness of the filter layer. Meanwhile, the manufacture of rice husk charcoal should use controlled combustion mechanisms and or husk charcoal activation with the chemical Na OH to strengthen the properties of the husk charcoal adsorbent against harmful chemical compounds.

Seasonal variation and correlation between the physical, chemical and microbiological parameters of Nile water in selected area in Egypt (Case study)

Fresh water resources in terms of water quality is a crucial issue worldwide. In Egypt, the Nile River is the main source of fresh water in the country and monitoring its water quality is a major task on governments and research levels. In the present case study, the physical, chemical and algal distribution in Nile River was monitored over two seasons (winter and summer) in 2019. The aims of the study were to check the seasonal variation among the different water parameters and also to check the correlations between those parameters. Water samples were collected from the Nile in Cairo governorate in EGYPT. The different physiochemical and microbiological properties in water samples were assessed. The studied parameters were included: temperature, turbidity, dissolved oxygen, chemical oxygen demand, pH, electric conductivity, total dissolved solids, total hardness, anions and cations. Also, the total algae count, blue-green algae, green algae, diatoms, unicellular and filamentous algae were monitored. The results revealed that during winter season the values recorded for (turbidity, total dissolved solids, pH, total alkalinity, total hardness, dissolved oxygen, chemical oxygen demand as well as nitrate, sulfate, chloride, fluoride ions, calcium and magnesium) were higher than during summer. While other parameters including ammonia, nitrite, silicate, carbon dioxide, phosphate, manganese, iron and residual aluminium were higher in summer compared to winter. The data showed a variation total algal count of 4600 to 6500 unit/ml in winter and varied from 3100 to 4500 unit/ml during summer season with predominance of diatoms. The recorded Pearson’s correlations indicated several significant correlations between tested parameters. In conclusion, although there were several variations in tested water quality parameters though all results were within the permissible limits set by the World Health Organization for drinking water.
