2016
Singare, Pravin U.
The present study deals with the investigation of existing pollution levels and potential ecological risk assessment of endocrine-disrupting organochlorine and organophosphorous pesticide residues in the Vasai Creek water near Mumbai. The average concentration of α- and β-endosulfan (137.75ng·L−1) exceeds the chronic criteria level of α- and β-endosulfan (6.5ng·L−1) set by US EPA for freshwater aquatic organisms. The concentration levels of aldrin (75.31ng·L−1), dieldrin (71.19ng·L−1) and endrin (76.60ng·L−1) was found to exceed the respective criteria levels of <0.13, 65.1, and 61ng·L−1 as set by US EPA for protection of freshwater aquatic organisms. In addition, the level of chlorpyrifos (208.77ng·L−1) exceeds the recommended concentration value of <35ng·L−1 set by Ministry of Environment of British Colombia. The results of our study give an indication of probable ecotoxicological risk to the marine breeding organisms of creek.
