In response to the growth of organic pollutants identified in surface water many multi-residue analytical strategies using enrichment steps have been used for the analysis of grab sampling. Recently, sampling systems more realistic of environmental exposition have been designed to measure mean concentrations of those xenobiotics to estimate their toxicological effects on the environment and populations. The ability to use one of these integrative samplers for the monitoring of Endocrine Disruptors and pharmaceuticals has been evaluated. Chemcatcher with C18 SPE disks and PES diffusion membrane have been rigorously calibrated for 49 emerging organic pollutants but also investigated for the Performance Reference Compounds (PRCs) approach. Samplers have been exposed for 28 days in 50L tanks with continuous renewal of spiked tap water for the adsorption study and spiked samplers for the desorption experiment. Most of the compounds of interest accumulate with relative good linearity (R² from 0.90 to 0.99) over 7 to 21 days on the Chemcatcher. Sampling rates were calculated for the C18 Chemcatcher (0.02 to 0.16 L/d) after confirmation of the maximal exposure time using the half time of equilibrium criteria. 3 molecules showed accumulation and desorption consistent with first order kinetics with similar half time of equilibrium and thus almost verifying all the criteria for the use of PRCs on passive samplers.
