Description
Summary:The uptake and bioconcentration of disulfoton (O, O-diethyl S-2-ethylthioethyl phosphorodithioate) and its oxidation compounds, sulfoxide and sulfone in carp were investigated by a continuous flow water system. Disulfoton concentration in fish increases rapidly after exposure to chemical and remains constant. No increase of bioconcentration factor (BCF) was observed with longer exposure and concentration in water. The BCF of disulfoton in carp was approximately 450. On transference of fish to fresh water free of disulfoton, the chemical disappeared quite rapidly from the fish body. The BCF of disulfoton sulfoxide and sulfone which are the ultimate residue compounds in the environment showed very low values. A significant correlation was found between the BCF in fish and the partition coefficient between n-octanol and water.
