Uptake of organochlorine pesticides by solvent-filled cellulose and polyethylene membranes.


Membrane-based passive samplers were used to study the uptake of organochlorine pesticides (lindane, aldrin, dieldrin, and chlorpyriphos) in a continuous-flow system. The membranes were filled with cyclohexane and a mixture of cyclohexane and triolein. Uptake of the chemicals was 24-84 times faster in polyethylene membranes compared to that in cellulose… (More)
