典型污染场地水土样品测试数据

数据集1主要是为了查明典型污染场地土壤和地下水的污染特征、污染物来源及其污染途径，识别场地特征污染物；分析典型场地特征污染物在地下水、土中的空间分布特征及其迁移转化过程，解析典型场地污染源汇关系，构建重点行业典型场地土壤、地下水的关键监测指标。因此需要对典型研究区地下水样品和土壤样品进行采集及测试工作。样品采集自燕山石化垃圾填埋场、北京某典型石油烃污染场地以及吉林某场地。在燕山石化垃圾填埋场共采集地下水样品15件，土壤样品13件，对土壤和地下水中特征污染物多环芳烃进行监测，并借助微生物基因组测定结果来分析污染物在土壤和地下水中的的迁移转化规律。在燕山某石油烃污染场地采集土壤样品5件，对土壤特征污染物多环芳烃和正构烷烃进行监测。在吉林某场地采集地下水样品5件，土壤样品4件，借助微生物来分析污染物在土壤中的的迁移转化规律，通过对地下水年代测定来确定地下水的源汇关系。数据量42.02MB。

Dataset 1 is primarily intended to ascertain the pollution characteristics, pollutant sources and pollution pathways of soils and groundwater at typical contaminated sites, as well as to identify the characteristic pollutants of such sites. It aims to analyze the spatial distribution patterns and migration-transformation processes of characteristic pollutants in groundwater and soil of typical sites, parse the source-sink relationships of pollution sources in typical sites, and establish key monitoring indicators for soils and groundwater at typical sites of key industries. Therefore, collection and testing of groundwater and soil samples from typical research areas are required. Samples were collected from three sites: the Sinopec Yanshan Refinery landfill site, a typical petroleum hydrocarbon-contaminated site in Beijing, and a site in Jilin Province. A total of 15 groundwater samples and 13 soil samples were collected at the Sinopec Yanshan Refinery landfill site; polycyclic aromatic hydrocarbons (PAHs), the characteristic pollutants in soil and groundwater, were monitored, and the migration and transformation rules of pollutants in soil and groundwater were analyzed based on microbial genome sequencing results. Five soil samples were collected from the typical petroleum hydrocarbon-contaminated site in Beijing, and the characteristic pollutants PAHs and n-alkanes in the soil were monitored. Five groundwater samples and 4 soil samples were collected from the site in Jilin Province; the migration and transformation rules of pollutants in soil were analyzed with the assistance of microbial data, and the source-sink relationships of groundwater were determined via groundwater dating. The total data volume of this dataset is 42.02 MB.
