Abstract
Soil serves as ultimate sink for pesticides applied directly to the soil or when applied on the crops. Organochlorine insecticides particularly HCH and DDT have been in use in Haryana, India for agriculture as well as public health purposes during the last 2-3 decades. Razik et al. (1988) reported residues of BHC, aldrin, dieldrin and p,p'-DDT in Nile river waters. The contamination of pond waters with a number of herbicides, fungicides and insecticides was demonstrated by Frank et al. (1990) in Ontario, Canada. The contamination of drinking water as well as ground water with organochlorine insecticides has been reported all over world (Bakra et al. 1990; Iwan 1990; Jani et al. 1991; Ritter 1991).
