Physico chemical water quality parameters

In addition to the economic successes, regional water environment has been and is being affected by increasing agricultural, industrial and daily–life wastes. Water pollution is a global problem, not just one country, or any one territory. To take specific measures to protect water resources, it is essential to assess the current state of water quality.

The study area was visited and surveyed twice in a month. During each visit waterfowl census was carried out and water samples were also collected to document changes in physico-chemical parameters and microbial analysis over the seasons. The aggregation of birds in the area is mainly related to the increase in migratory population of birds during winter. The variations inland bird aggregations as well as physico-chemical factors are discussed.

Lentic systems are a diverse set of inland freshwater habitats (Lakes and ponds) exist across the globe and provide essential resources and habitats for both terrestrial and aquatic organisms. The current work was intended to evaluate the quality of the selected ponds (Pond 1, 2 and 3) in and around Vellore district, TamilNadu. The water samples were collected to determine the physical and chemical parameters during every month in the year 2019. Water parameters such as temperature, pH, dissolved oxygen, Alkalinity, electrical conductivity, Chloride, Sulphate, Nitrate, Ca, Cl was studied.

The physico-chemical ex-situ study was conducted for 21 groundwater sample of SIDCUL - Udham Singh Nagar district, Uttarakhand. The various physicochemical parameters such as pH, Electrical Conductivity (EC), Total Dissolved Solids (TDS), Calcium (Ca2+), Magnesium (Mg2+), Sodium (Na+ ), Potassium (K+ ), Bicarbonate (HCO3), Carbonate (CO3), Chloride (Cl- ), Turbidity and Nitrate (NO3) were determined using standard procedures. BIS water quality standard for drinking purpose was used to compare the results.

The present investigation has been carried out for determining the various physicochemical and biological parameters prevailing in Vembanad Lake of Panangad region, Kochi. The water samples were collected fortnightly from the Panangad-Kumbalam region for a period of ten months (September, 2015 to June, 2016). Meteorologically the whole study period can be classified as South west monsoon (September, 2015), Post-monsoon (October -November, 2015), North east monsoon (December, 2015 to March 2016), Premonsoon (April May, 2016) and beginning of south west monsoon (June, 2016).

The quality of drinking water is an important environmental determinant of health. In present study, carried out of physico-chemical analysis of drinking water like public drinking water, surface water, ground water and animal drinking water were collected from different parts of urban and peri-urban areas of Udaipur. Parameters such as pH, electrical conductivity, turbidity, total dissolved solids (TDS), total hardness, nitrate, fluoride, iron, chloride and residual free chlorine were analyzed and range were founded 6.80 to 8.

The present study was undertaken to evaluate the nutritional quality and value addition of Black gram grown in H.P. Three cultivars/varieties of Black gram viz. UG-218, HIM MASH and Local cultivar were taken for the study. The various biochemical parameters studied were physico-chemical characteristics, proximate compositional, nutritional quality, functional properties and anti-nutritional constituents. The results of the investigation showed that UG-218 had maximum length, breadth and 1000 seed weight as compared to HIM MASH and Local cultivar.
