Integrative samplers for the monitoring of PCBs in the dissolved phase of aquatic media: the ECLIPSE project

Abstract : The development of innovative sampling and analytical tools for monitoring PCBs in surface and groundwater is needed to better understand their transfer processes in aquatic environments and thus, to assess risks and opportunities of remediation. Various samplers at different stages of development are now available to estimate time averaged freely dissolved concentrations of hydrophobic contaminants in aquatic media. The ECLIPSE project aims to compare and evaluate the performance of 6 integrative samplers: semi-permeable membrane device (SPMD by Cemagref), low density polyethylene strips (Ifremer), silicon membranes (Deltares), chemcatcher (BRGM), continuous-flow integrative sampler (CFIS) and sorbisense (Suez-Environnement). The first step is the simultaneous calibration of these samplers under laboratory conditions. They are exposed under constant agitation to water spiked with PCB during periods from 1 to 90 days in a stainless steel tank. Dosing and maintaining a constant PCB concentration in the water phase is achieved by immersing a large amount of spiked silicone rubber sheets [Rusina, 2009, submitted]. In field studies, these samplers will be exposed in a comparative way on several field locations, e.g. two along the Rhône River, and one in a river and/or groundwater in the vicinity of a polluted industrial site. The in situ implementation of these tools will be followed by chemical analysis for the monitoring of PCB contamination in surface and groundwater. Evaluation will include limits of detection and quantification, concentration factors, repeatability, accuracy of measurements, period of exposure, accumulation kinetics (in situ and in laboratory) and suitability for quantifying time averaged concentrations of PCBs in the dissolved phase. This work will help to harmonize practices in the use of these innovative sampling tools, especially through technical exchanges and inter-laboratories comparison tests. Edition of practical user guides will ensure their valorization and their application for monitoring of water quality.
