摘要：

The affinity of selected organochlorine, pyrethroid and triazine pesticides at concentrations less-than-or-equal-to 0.25 ppb to glass, PTFE and a range of filtration membranes is reported. For the organochlorine pesticides, the adsorption behaviour correlates well with the octanol-water partition coefficients. The triazines are not adsorbed to glass or PTFE whereas alpha-BHC, lindane, dieldrin and endrin are weakly adsorbed compared with DDT, DDE, TDE, permethrin, cypermethrin and fenvalerate. The retention of the pesticides on different membrane filters is variable with the lowest uptake by the inorganic filters. Adsorption constants are calculated to quantify the sorption affinity of the compounds on glass, PTFE and the selected filters.
