Data set on stormwater micropollutants collected during the INOGEV research program

This data set was collected during the INOGEV research program, funded by the French National Research Agency.The dataset gives event mean concentrations of urban stormwater, measured on three French catchments for a wide range of contaminants (n=77) over the period July 2011- May 2013. The studied contaminants include conventional stormwater contaminants (polycyclic aromatic hydrocarbons - PAHs, Zn, Cu, Pb, etc.), as well as poorly or undocumented pollutants such as nonylphenol and octylphenol ethoxylates (NPnEO and OPnEO), bisphenol A (BPA), polybrominated diphenyl ethers (PBDEs), a wide variety of pesticides and various metals of relevance (As, Ti, Sr, V). Sampling and analysis were performed using homogeneous and standardised methods on three urban catchments with different land use patterns located in three distinct French towns., i.e. Sucy in Paris conurbation, Pin Sec in Nantes and Chassieu near Lyon. Their areas range from 30 to 228 ha and their impervious surface coefficients (ISC) vary between 27% (Sucy) and 75% (Chassieu). Chassieu is an industrial area, whereas the other two catchments are mainly residential. These catchments are all drained by separate storm sewers. Stormwater was sampled using automatic samplers equipped with Teflon® pipes and plastic or glass bottles; samples were then controlled through a flow-meter in order to derive flow proportional event mean concentrations (EMC). Glass bottles were used for most organic pollutants, while plastic bottles were introduced for metals and three pesticides (glyphosate, glufosinate and its metabolite amino methyl phosphonic acid - AMPA) to avoid any potential sorption. Between two and 14 rain events were analysed for a given family of compounds on a given catchment. All organic compounds were analyzed over both the dissolved (<0.45 µm) and particulate phases, while metals were analysis over total and dissolved phases. Metals were analyzed by Inductively Coupled Plasma - Mass Spectrometry (ICP-MS) for the most part or by ICP-AES for Zn, in accordance with French standards (NF X 31-147) on the total and dissolved fractions. All organic pollutants were analyzed by either gas or liquid chromatography with a fluorescence detector or with a simple, tandem or time-of-flight mass spectrometer for both the dissolved and particulate fractions. All pollutants were quantified using internal standards calibration.THIS DATASET IS ARCHIVED AT DANS/EASY, BUT NOT ACCESSIBLE HERE.
