Abstract
Five different passive sampler devices were characterized under laboratory conditions for measurement of 124 legacy and current used pesticides in water. In addition, passive sampler derived time-weighted average (TWA) concentrations were compared to time-integrated active sampling in the field. Sampling rates (R-S) and passive sampler-water partition coefficients (K-PW) were calculated for individual pesticides using silicone rubber (SR), polar organic chemical integrative sampler (POCIS)-A, POCIS-B, Chemcatcher (R) SDB-RPS and Chemcatcher (R) C-18. The median R-S (Lday(-1)) decreased as follows: SR (0.86) > POCIS-B (0.22) > POCIS-A (0.18) > Chemcatcher (R) SDB-RPS (0.05) > Chemcatcher (R) C-18 (0.02), while the median logK(PW) (Lkg(-1)) decreased as follows: POCIS-B (4.78)> POCIS-A (4.56) > Chemcatcher (R) SDB-RPS (3.17) >SR (3.14)> Chemcatcher (R) C-18 (2.71). The uptake of the selected compounds depended on their physicochemical properties, i.e. SR showed a better uptake for more hydrophobic compounds (log octanol-water partition coefficient (K-OW) > 5.3), whereas POCIS-A, POCIS-B and Chemcatcher (R) SDB-RPS were more suitable for hydrophilic compounds (logK(OW) < 0.70). Overall, the comparison between passive sampler and time-integrated active sampler concentrations showed a good agreement and the tested passive samplers were suitable for capturing compounds with a wide range of K-OW's in water.
