天津子牙电子垃圾拆解地土壤样品中重金属GI和NPI法评价环境风险数据（2015年）

本数据集根据我国北方典型的电子垃圾拆解地天津静海县子牙电子垃圾拆解地为研究区域，于2015年根据子牙电子垃圾拆解地的实际情况采集42个土壤样品，其中Cr、Ni、Cu、Zn、Cd、Pb、Be、V、Co、Sb、Tl、B通过微波消解后采用电感耦合等离子体质谱仪测定，As和 Hg通过王水消解后采用原子荧光分光光度计测定，获得重金属的调查结果并通过GI和NPI法评价环境风险。数据集有588条记录。This dataset takes the typical e-waste dismantling site in northern China, the Ziya e-waste dismantling site in Jinghai District, Tianjin, as the research area. A total of 42 soil samples were collected in 2015 based on the actual conditions of the Ziya e-waste dismantling site. The concentrations of Cr, Ni, Cu, Zn, Cd, Pb, Be, V, Co, Sb, Tl and B were determined via inductively coupled plasma mass spectrometry (ICP-MS) after microwave digestion, while As and Hg were determined via atomic fluorescence spectrophotometer after aqua regia digestion. The survey data of heavy metals were obtained, and the environmental risks were evaluated using the GI and NPI methods. The dataset contains 588 records in total.
