2008年湖南株洲有色金属冶炼区数据

数据库以湖南株洲有色金属冶炼区采集的52组农作物（可食部分）及对应根际土壤为对象，分析测试了农作物（可食部分）及土壤中Cr、Cd、Pb、As、Ni、Zn等重金属含量。获得的数据，对于开展硫化物矿地质高背景农田农作系统中重金属的循环特征研究、编制《硫化物矿区农田土壤镉生态风险评价与防控技术标准草案》，起到了重要支撑作用。This dataset focuses on 52 pairs of crop edible portions and their corresponding rhizosphere soils collected from the non-ferrous metal smelting region in Zhuzhou, Hunan Province, China. The concentrations of heavy metals including Cr, Cd, Pb, As, Ni, and Zn in both the crop edible portions and the soils were analyzed and quantified. The acquired data has provided critical support for two key tasks: research on the cycling characteristics of heavy metals in farmland cropping systems with high geogenic background of sulfide ore deposits, and the drafting of the "Draft Technical Standard for Ecological Risk Assessment and Prevention and Control of Cadmium in Farmland Soils of Sulfide Mining Areas".
