The semipermeable membrane device (SPMD), consisting of a neutral lipid (triolein) enclosed in polyethylene layflat tubing, is very effective in sequestering bioavailable organochlorine (OC) pesticides in the environment. We used SPMDs to sequester OC pesticide residues in streams receiving irrigation drainwater and found toxaphene, the DDT complex, dieldrin, and endrin. Ambient water concentrations of the OC pesticides were calculated using an algorithm developed previously. Toxaphene residues were estimated to range from 300 to 7,000 ng/L.
