16 17 POCIS (Polar Organic Chemical Integrative Sampler) is a relatively recent integrative 18 sampler developed to trap hydrophilic organic micropollutants in aquatic environments. 19 Nevertheless, at present, there is no review dealing specifically with this tool. The aim of this paper was to compile information from numerous references based on 21 POCIS(More)
We created a database in order to quantitatively assess the occurrence and removal efficiency of pharmaceuticals and personal care products (PPCPs) in wastewater treatment plants (WWTPs). From 117 scientific publications, we compiled 6641 data covering 184 PPCPs. Data included the concentrations of PPCPs in WWTP influents and effluents, their removal(More)
This study reports on the occurrence and behaviour of six pesticides and one metabolite in a small stream draining a vineyard catchment. Base flow and flood events were monitored in order to assess the variability of pesticide concentrations according to the season and to evaluate the role of sampling frequency on the evaluation of fluxes estimates.

The aim of this study was to investigate the effects of cadmium on physiological and behavioural responses in Gammarus pulex. In a first experiment, cadmium LC50s for different times were evaluated in 264 h experiment under continuous mode of exposure (LC50(96 h)=82.1 microgL(-1), LC50(120 h)=37.1 microgL(-1), LC50(168 h)=21.6 microgL(-1), LC50(264 h)=10.5(More)
The responses of aquatic organisms to chronic exposure to environmental concentrations of toxicants, often found in mixtures, are poorly documented. Here passive sampler extracts were used in experimental contamination of laboratory channels, to investigate their effects on natural biofilm communities. A realistic mixture of pesticides extracted from Polar(More)
Estrogens act as endocrine disruptors and are known to be discharged in the aquatic environment via effluents from wastewater treatment plants. Efficient analytical protocols are needed to identify and quantify estrogens in wastewaters and aquatic environments in order to study their sources, levels of exposure and modes of transfer. We developed and(More)
11 Stir bar sorptive extraction followed by liquid desorption and high performance liquid 12 chromatography with tandem mass spectrometry (SBSE-LD-LC-MSMS) has been developed for the 13 determination of 15 pesticides or selected metabolites from different families (herbicides, insecticides, 14 fungicides) in surface water samples. The optimization of(More)
Grab sampling and automated sampling are not suitable or logistically too constraining for the monitoring of pesticides in dynamic streams located in agricultural watersheds. In this work, we applied stir bar sorptive extraction (SBSE) Twisters® directly in two small rivers of a French vineyard (herein referred to as "passive SBSE"), for periods of one or(More)

Estrogenic disrupting potency was studied in rivers and wastewaters in the Orge catchment near Paris area, using analytical and biological approaches simultaneously. The MELN test was applied to surface water samples, urban storm runoff and WWTP effluent in parallel to analytical determinations of natural estrogens and synthetic estrogen (ethinylestradiol)(More)
In this work, the low cost synthesis of polydimethylsiloxane (PDMS) rods is described, and the performances of this new passive sampling device (in laboratory and in situ) are compared to the passive stir bar sorptive extraction (SBSE) for the monitoring of pesticides from different classes (herbicides, insecticides and fungicides) in surface waters.
