Long-term observation of the wastewater from the Parisian conurbation

Wastewater contains a wide range of biological and chemical markers related to human activity. The collection and analysis of these markers in the effluents (wastewater and sludge) allow make it possible to qualify the public health of the population and to evaluate the impact of the chemicals used in daily life on the environment.<br> In line with these studies, the Innovation Department of SIAAP and its scientific partners (ISA and LEESU) have created an Observatory of the city with the objectives of:<br> • Monitoring the long-term dynamics of known and/or potential pollutants according to French regulations.<br> • Contributing to studies aimed at a better understanding of anthropogenic activities.<br> • Structuring and centralizing data (wastewater and end-of-treatment sludge), ensuring their storage for 10 years.<br> • Providing technical and scientific knowledge by publishing every two years the data generated by the Observatory of the city via the open platform Zenodo.<br> Regarding the pre-treated wastewater, the Clichy pretreatment plant has been chosen as a strategic location because it collects wastewater from the Paris catchment area (2.7 million inhabitants). Data on the wastewater quality during dry weather and on rain events (biological and physicochemical global quality parameters, metals, polycyclic aromatic hydrocarbons – PAHs and polychlorinated biphenyls – PCBs) is available since 2000 (for dry weather) and from 2005 (for rain events). <strong>Dataset description</strong> The dataset “Dataset _Clichy-SEC-Inlet.xlsx” includes the monthly analysis of various micro pollutants (trace metals, PAHs and PCBs) and usual physico-chemical parameters. The oldest analyses date back to 2000. The dataset “Dataset _Clichy-CSO.xlsx” includes the monthly quantified analysis of various micro pollutants (trace metals, PAHs and PCBs) and usual physico-chemical parameters for samples collected during 384 rain events. The oldest analyses date back to 2005. Details on each analysis are provided in the “Dataset_analyticalmethods_Clichy.xlsx” The following files are available: Dataset _Clichy-SEC-Inlet.xlsx Dataset _Clichy-CSO.xlsx Dataset_analyticalmethods_Clichy.xlsx污水中含有大量与人类活动相关的生物与化学标志物。对出水（污水与污泥）中的此类标志物进行采集与分析，可用于评估人群公共健康水平，以及日常使用的化学品对环境造成的影响。 基于此类研究，SIAAP创新部门与其科研合作伙伴ISA、LEESU共同打造了城市观测站，其目标如下： • 依据法国相关法规，对已知及潜在污染物的长期动态变化进行监测； • 助力相关研究，以深化对人为活动的认知； • 对数据（污水与处理后污泥）进行结构化整合与集中存储，并保障数据可留存10年； • 通过开放平台Zenodo每两年发布城市观测站生成的相关数据，以提供技术与科学知识支持。 针对预处理后的污水，研究团队选定克里希预处理厂作为战略采样点，因其接收来自巴黎集水区（覆盖270万人口）的污水。该厂的水质数据涵盖干旱天气与降雨事件两种场景，包括生物与理化综合水质参数、金属、多环芳烃（PAHs）及多氯联苯（PCBs），其中干旱天气水质数据自2000年起可获取，降雨事件相关数据自2005年起可获取。 <strong>数据集说明</strong> 数据集"Dataset _Clichy-SEC-Inlet.xlsx"包含各类微污染物（痕量金属、PAHs及PCBs）与常规理化参数的月度分析结果，最早的分析数据可追溯至2000年。 数据集"Dataset _Clichy-CSO.xlsx"包含针对384次降雨事件采集的样本的各类微污染物（痕量金属、PAHs及PCBs）与常规理化参数的定量月度分析结果，最早的分析数据可追溯至2005年。 各分析项的详细说明均收录于"Dataset_analyticalmethods_Clichy.xlsx"中。 本次公开的数据集文件如下：Dataset _Clichy-SEC-Inlet.xlsx、Dataset _Clichy-CSO.xlsx 及 Dataset_analyticalmethods_Clichy.xlsx。
