INOGEV_stormwater_micropollutants

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 (&lt;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.本数据集采集自法国国家研究署（French National Research Agency）资助的INOGEV研究项目。数据集记录了2011年7月至2013年5月期间，法国3个城市汇水区内雨水的事件平均浓度（event mean concentrations, EMC），共覆盖77种污染物。本次研究涉及的污染物涵盖常规雨水污染物（多环芳烃（polycyclic aromatic hydrocarbons, PAHs）、锌（Zn）、铜（Cu）、铅（Pb）等），以及鲜有报道或未被广泛记录的污染物，如壬基酚与辛基酚乙氧基化物（NPnEO、OPnEO）、双酚A（BPA）、多溴二苯醚（PBDEs）、多种农药，以及砷（As）、钛（Ti）、锶（Sr）、钒（V）等相关金属元素。 本次采样与分析采用统一标准化方法，覆盖法国3个具有不同土地利用模式的城市汇水区，分别位于巴黎都会区的叙西（Sucy）、南特的潘塞克（Pin Sec）以及里昂附近的沙谢厄（Chassieu）。这3个汇水区的面积介于30至228公顷之间，不透水面系数（impervious surface coefficients, ISC）从27%（叙西）到75%（沙谢厄）不等。其中沙谢厄汇水区为工业区，其余两个汇水区以居住用地为主，所有汇水区均采用分流制雨水管网排水。 雨水采样采用配备特氟龙（Teflon®）管路的自动采样器，采样容器分为塑料瓶与玻璃瓶；采样过程通过流量计监控，以获取与流量成正比的事件平均浓度（EMC）。多数有机污染物的样品采用玻璃瓶储存，而金属元素与3种农药（草甘膦、草铵膦及其代谢产物氨甲基膦酸（AMPA））的样品则使用塑料瓶储存，以避免潜在的吸附损失。针对每个汇水区的某一类化合物，共分析2至14场降雨事件的样品。 所有有机污染物均分别检测溶解相（<0.45 µm）与颗粒相中的含量，而金属元素则检测总相与溶解相中的含量。金属元素的检测大多采用电感耦合等离子体质谱法（Inductively Coupled Plasma - Mass Spectrometry, ICP-MS），锌元素则采用电感耦合等离子体原子发射光谱法（ICP-AES），检测过程符合法国标准NF X 31-147中关于总相与溶解相组分的分析要求。所有有机污染物的检测均采用气相色谱或液相色谱结合荧光检测器，或结合单极、串联或飞行时间质谱仪的方法，覆盖溶解相与颗粒相两个组分。所有污染物均采用内标校准法进行定量分析。
