Man’s activities on the environment often results in pollution and degradation of water bodies. Water bodies must therefore be jealously guided and protected from being polluted, which will affect water quality and availability for desired usage. Causes of water quality impairment are urban and rural storm water runoff, inadequate waste water treatment, nutrient entrophication, atmospheric deposition...
Arsenic (As) is a metalloid that causes severe water pollution due to its extravagant toxicity. Ceriodaphnia dubia, a freshwater crustacean, was selected as a model system to evaluate the degree of time and dosage dependent acute toxicity caused by pentavalent As [As(V)]. C. dubia were collected from a natural pond and treated with different concentrations of As(V) for 24 hours and 48 hours. For both...
With population growth, rising living standards and increasing attention given to environmental issues Water resources management has increased in many countries, water is fast becoming a scarce input. It is study of human development in the twentieth century, and a judgment is only a question of human optimization of water resources and their future generations what it was composed of such questions...
Gram-negative bacteria isolated from the abattoir effluent on surface water of River Katsinaala in rainy and dry seasons were Escherichia coli; Klebsiella spp; Proteus vulgaris; Salmonella typhi and Gram-positive bacterium isolated was Streptococcus faecalis. In rainy season, the lowest mean bacterial count was from E.coli (0.0067+0.031 CFU/ml) and highest mean bacterial count from Salmonella typhi...
Hematological and some biochemical contents of the blood in relation to physico- chemical characteristics of the water have been studied in the fresh water fish, Notopterus notopterus. The results indicated that normal values have been found in comparison to the studies carried out in other fishes. Hence, the fish Notopterus notopterus is having favorable environmental temperature, pH and dissolved...
The current study deals with water quality variations and micro algal community structure in the highly eutrophic pond. Several water quality parameters were evaluated during the period from July 2014 to June 2015 from sampling station sited from Annamalai Nagar viz., Pasupatheswarar temple pond. The water quality parameters like Air and water temperature, turbidity, electrical conductivity, total...
This study aims at monitoring physico-chemical features of the waters of the Hârtibaciu River in Romania with a view to establishing its qualitative benchmarks. Using the waters of this river for agricultural purposes leads to the establishment of its physical and chemical features and its falling within the related quality group. This study has monitored general chemical indicators and specific chemical...
This paper aimed at underlying some physico-chemical characteristics of the water of Lake Lanao at Poona-bayabao, Lanao Del Sur during the first quarter of 2015, by evaluating a total of eight (8) water quality parameters. Physical parameters were temperature, depth, transparency, and total suspended solids. On the other hand, the chemical parameters were pH, dissolved oxygen, phosphate and nitrate...
The quality of the surface water (rivers) around Warri metropolis was evaluated using Water Quality Index (WQI) techniques. The study was carried out to assess the suitability of the water samples collected from different river bodies’ around Warri metropolis. The water quality index (WQI) was determined based on their various physico-chemical parameters such as pH, temperature, dissolved oxygen,...
