土壤/沉积物生态风险评价方法技术研究进展

Progress of Ecological Risk Assessment Method and Techniques for Soil and Sediment

在我国,生态风险评价受到越来越多的重视,而有关方法的探讨还很欠缺。本文详细介绍了灾害商法、酸性挥发性硫化物、生物—土壤/沉积物—累计—因数法、风险评估编码、潜在生态风险指数法等生态风险评价的方法和技术,并讨论了生态风险评价模型。

Ecological risk assessment was getting more and more important in China now, but it was still lack of determination method. In this paper, we tried to make a conclusion of these method and tools, including HQ（Hazardous Quotient）, AVS/SEM （SEM：Sequential extracted metal, AVS： Acid Volatile Sulfide）, especially for heavy metals, BSAF for the organics, RAC（Risk Assessment Code）and RI（Risk Index）. Several commonly and. newly used risk assessing models were also discussed.
