PHYSICO–CHEMICAL ANALYSIS OF WATER SAMPLES COLLECTED FROM THE SELECTED STUDY AREAS OF RANIPET DISTRICT, TAMIL NADU, INDIAA. MANGAYARKARASI AND M. AKILANAbstract Various organic and inorganic pollutants present in the industrial effluents released into the aquatic ecosystem. This pollutant is harmful to the aquatic biota and also leads to the bioaccumulation in the terrestrial biota. Five different sampling sites (S1-S5) are selected for this study. The physico-chemical parameters such as pH, temperature, turbidity, electrical conductivity, total hardness, total dissolved solids, calcium, magnesium, sulphate, ammonia, nitrite, nitrate, chloride, biochemical oxygen demand and chemical oxygen demand of the water samples are analyzed by standard protocols and the data are interpreted by student t test and ANOVA. Results evidenced the significantly varied physico-chemical parameters, especially TH and TDS levels were beyond the permissible limit. |
