| The Water European Framework Directive requires the implementation of programs to monitor the chemical quality of water bodies (freshwater, transition water and seawater), based on grab measurements of concentrations of various contaminants (metals, organic compounds). The results are limited by several analytical difficulties, and the poor representativity because of the temporal variability of contamination. The passive sampling techniques, which basically consist of concentrating substances on a submerged device for a given period, and analyzing accumulated substances, should improve the monitoring, by simplifying analytical issues (lower detection limits, analysis in a simpler matrix), and allowing time integration of the contamination. Here, we... |

| The AQUAREF group of experts has been asked to take position on the use of passive integrative samplers (PIS) in a Water Framework Directive (WFD) context. The main objective of this 2015 present note is to complete (as much as possible) the 2014 report concerning the possibility of using PIS in comparison with current regulatory surveillance, for the WFD reporting in coastal and continental waters. The SBSE extraction technique was also taken into account for hydrophobic organic substances, as this technique limits the drawbacks of water samples transport (substance degradation in water samples, extra-cost induced by sample volume and weight) for remote sites like French overseas territories. The AQUAREF group took in consideration: on the one hand the... |
