POLYETHERSULFONE AS SUITABLE PASSIVE SAMPLER FOR WATERBORNE HYDROPHOBIC ORGANIC COMPOUNDS - LABORATORY CALIBRATION AND FIELD TEST IN THE SOSIANI RIVER, KENYA
Chepchirchir, B.S., X. Zhou, A. Paschke, and G. Schuurmann.
Science of The Total Environment 699:134056(2020)
A polyethersulfone (PES) membrane was deployed in a field test as a cost-saving and less labor-intensive single-phase passive sampler to measure waterborne hydrophobic organic compounds (HOCs), such as organochlorine pesticides, PCBs, and PAHs. Following laboratory tests, the PES membranes were tested in a field trial in a tropical river against the well-established silicone rubber (SR) sheets. Laboratory-based Rs for PES generated under field-relevant temperature and water flow velocity were used to calculate time-weighted average concentrations in the lower ng/L range, which are comparable (within a factor of two) with those derived from accumulated amounts in SR sheets (using in situ sampling rates).
