For site-specific soil ecological risk assessments (SERAs), an integrated chemical, ecotoxicological, and ecological analysis needs to be performed. The SERA guidelines of international institutions and countries recommend that a SERA be initiated at the screening level to save time and social economic cost; however, they provide no unified test species for this screening level. This study performed SERAs for field soils and confirmed the importance of selecting bioassay test species that reflect the ecotoxicity of field soils at the screening level. To confirm test species that reflect the ecological risk of field soils, correlation analysis was performed on the results of each bioassay with the integrated ecotoxicological risk index (EtoxRI). Our results showed that soil algae, nematodes, and plants were the most representative species in soil assays, with high correlation coefficients with EtoxRI. The results imply the importance of selecting test species that represent ecological risk for the screening level of SERAs. Based on these findings, when using SERAs, species sensitivity, ecological relevance, and economic aspects should be considered when selecting the bioassay test species.

在土壤生态风险评估的筛选水平上选择生物测定测试物种

对于特定地点的土壤生态风险评估（SERA），需要进行综合的化学，生态毒理和生态分析。国际机构和国家的SERA指南建议在筛选级别启动SERA，以节省时间和社会经济成本；但是，他们没有为此筛选水平提供统一的测试物种。这项研究对田间土壤进行了SERAs试验，并证实了选择能够在筛选水平上反映田间土壤生态毒性的生物测定测试物种的重要性。为了确定能够反映田间土壤生态风险的测试物种，对每种生物测定结果进行了相关分析，并采用了综合的生态毒理风险指数（EtoxRI）。我们的结果表明，土壤藻类，线虫，植物是土壤测定中最具代表性的物种，与EtoxRI的相关系数高。结果表明选择对于SERAs筛选水平具有生态风险的测试物种的重要性。基于这些发现，在使用SERA时，在选择生物测定测试物种时应考虑物种敏感性，生态相关性和经济方面。
