Abstract

This paper presents a discussion involving practical aspects of applying contamination indices and ecological risk factors derived from chemical elements in the environmental assessment of soils and sediments. The single and integrated indices: Geoaccumulation index (I_geo), Enrichment factor (EF), Contamination factor (CF), Pollution Index (PI), Ecological risk factor (E_i_r), Pollution Load Index (PLI), Degree of contamination (C_deg), Modified Contamination Factor (mC_deg), and potential ecological risk index (PERI) were discussed, and some applications were presented didactically. The analytical care needed to obtain reliable indices with the studied ecosystem is also evidenced. In addition, the advantages and limitations of the use of these indices are presented.

污染指数和生态风险在土壤和沉积物中化学元素污染评价中的应用。实用方面

本文讨论了在土壤和沉积物环境评价中应用由化学元素衍生的污染指数和生态风险因子的实际问题。讨论了土壤累积指数(Igeo)、富集因子(EF)、污染因子(CF)、污染指数(PI)、生态风险因子(Eir)、污染负荷指数(PLI)、污染程度(Cdeg)、修正污染因子(mCdeg)和潜在生态风险指数(PERI)等单一指标和综合指标，并给出了一些应用实例。还证明了获得研究生态系统的可靠指数所需的分析护理。此外，还介绍了这些指标的优点和使用的局限性。
