| 摘 要： | 以成渝经济区主要水系水体沉积物为研究对象,利用Eri（单一金属潜在生态风险因子）和RI（多金属潜在风险指数）等定量诊断工具分析沉积物中的重金属的潜在生态风险,为成渝经济区战略环评提供数据支撑。根据风险指标评价结果和重金属空间分布规律,将区域水系分为3种生态风险功能区。结合沉积物中重金属赋存形态,得出区域Cd的生态风险较...

| Abstract: | River sediments in Chengyu Economic Zone were analyzed in quantity by applying Eir(potential ecological risk factor of single heavy metal)and RI(multi-metal potential ecologic risk index),which provided data to support strategy environmental assessment in this district.According to the results of ecological risk assessment and the space distribution of heavy metals,the regional water system is classified into three functional areas.Considering the chemical speciation of heavy metals in the sediments,it conc... |
