Abstract：
Currently, data that guide safe concentration ranges for inorganic mercury in the soil are lacking and subsequently, threaten soil health. In the present study, a species sensitivity distribution (SSD) approach was applied to estimate critical mercury concentration that has little (HC5) or no effect (PNEC) on soil biota. Recently published terrestrial toxicity data were incorporated in the approach. Considering total mercury content in soils, the estimated HC5 was 0.6 mg/kg, and the PNEC was 0.12-0.6 mg/kg. Whereas, when only water-soluble mercury fractions were considered, these values were 0.04 mg/kg and 0.008-0.04 mg/kg, respectively.
摘要：
目前,缺乏指导土壤中无机汞安全浓度范围的数据，威胁土壤健康。在本研究中,采用物种敏感性分布（SSD）方法来估算对土壤生物区系影响很小（HC5）或没有影响（PNEC）的临界汞浓度。该方法纳入了最近发表的陆地毒性数据。考虑到土壤中的总汞含量，估计HC5为0.6mg/kg，PNEC为0.12-0.6mg/kg。然而,当仅考虑水溶性汞馏分时，这些值分别为0.04mg/kg和0.008-0.04mg/kg，分别。
