| Abstract: | Concentrations of DDT, HCH, aldrin and endosulfan were determined in river dolphins from the River Ganges, Patna. Among the organochlorines studied in the dolphins, DDT concentration was highest followed by HCH. This shows exposure of dolphins to these organochlorine pesticides. Presences of organochlorines to higher degree in tissues suggest that the river dolphins be at greater risk due to pesticidal contamination of the river system. |
