Aquatic pollution in Mithi River of Mumbai: assessment of physico–chemical parameters
The present investigation along Mithi River of Mumbai deals with the study of physico–chemical parameters like pH, conductivity, solid content, hardness, chloride, sulphate/sulphide, phosphate, biochemical oxygen demand (BOD), chemical oxygen demand (COD), surfactants, oil/ grease and phenol content in river water samples. The study was performed for the period of two years from 2009 to 2011, at three different sampling stations of Mithi River namely airport, CST Kalina road and Taximen's Colony Bandra Kurla Complex (BKC). From the results it appears that values of most of the physico–chemical parameters were very much above the permissible limit set for inland surface water. The values of various physico–chemical parameters studied in the present investigation were above those reported by Maharashtra Pollution Control Board (MPCB) in 2004. It was observed that results of various physico–chemical parameters obtained for the year 2010 to 2011 were higher than that of 2009 to 2010.
