Determination of uptake kinetics and sampling rates for 56 organic micropollutants using “pharmaceutical” POCIS

► We present a reliable and robust calibration system for “pharmaceutical” POCIS. ► We discuss the accumulation kinetics for 56 organic micropollutants. ► We calculate accurate sampling rates (Rs) for 43 micropollutants (16 unpublished). ► We find correlation between Rs and log D for some micropollutant families. ► We discuss the validity field of POCIS according to micropollutants.
