Description
Summary:•In-situ calibration of MPT with WAX sorbent for pesticides and pharmaceuticals.•First calibration of MPT device with time-varying analyte levels and water flows.•Sampling rates for 24 pesticides and pharmaceuticals were 1.32–17.1 mL d−1.•Estimated sampling rates consistent with those from a prior study on WWTP influent.•Analyte uptake controlled by diffusion in PE matrix and/or aqueous pores of sampler.
