Impact of phosphate fertilizers to aquatic ecosystem: A case study

Abstract

Most of the reservoirs and fresh water bodies in the developing countries are suffering from water contamination issues. Therefore it is becoming difficult to maintain good water quality which is safe for animal and human consumption. The water supply is under extreme stress due to rising demand and careless use habits. The present study aims to correlate the Total phosphorus with other water quality parameters have been collected monthly from five sampling sites of Tiru reservoir, Udgir, Dist: Latur, Maharashtra from February 2018 to January 2019. Seasonal patterns in physicochemical parameters determined from the surface water of the Tiru reservoir have been studied. The correlation coefficients of 18 water quality metrics were calculated to determine which water parameters are really contributing to pollution. In situ water quality assessments showed that TP concentrations highest in the summer, when reservoir levels were lowest. Total phosphorus associated strongly with Chl-a (0.925). Eutrophication, caused by phosphorus in water, raises chlorophyll-a levels (algal blooms).
