Field Calibration of Semipermeable Membrane Devices (SPMDs) for Persistent Organic Pollutant Monitoring in a Reservoir

Persistent Organic Pollutants (POPs) in water can reach levels below ppt (ng L−1), representing a challenge for risk assessment using long-term exposure. Therefore, sampling devices to monitor trace of organic compounds are suitable due their sensitivity and low detection limits. In this work, the field calibration monitoring POPs, such as Polycyclic Aromatic Hydrocarbons (PAHs) pesticides, drinking reservoir were carried out semipermeable membrane (SPMDs). The SPMDs spiked with deuterated PCBs used PRCs, dissipation was measured at 5, 10, 15 24 days. dialyzed hexane twice initial amount (N) final (No) PRCs extracts estimated by GC/MS calculate rate (Rs) target compounds. dissipated more than 30% days, Rs calculated between 27.8 72.7 L day−1 PAHs 35.8 71.3 pesticides. Finally, PAH congeners Naphthalene, Acenaphthylene, Acenaphthene, Fluorene, Phenanthrene, Anthracene, Fluoranthene Pyrene detected concentration (Cw) ranges 0.5 2.7 ng L−1, whilst chlorpyrifos only pesticide 19.0 L−1 reservoir. This showed that do not dissipate entirely days modelling may be applied Cw estimation POPs reservoirs.
