Résumé / Abstract
Passive sampling has been developed for representative and reliable monitoring of organic micropollutants such as pesticides in freshwaters. Prior to field exposure, a calibration of the passive samplers is required to obtain reliable time-integrative average concentrations. In this study two different experimental systems were tested and compared with continuous flow or static mode for the calibration of 20 pesticides with a varying range of log Kow (2.18-5.11). We compared the characteristics of both systems (consumption of water and pesticides, stability of pesticide concentrations) and the obtained calibration coefficients (sampling rates).
