Selecting Bioassay Test Species at the Screening Level of Soil Ecological Risk Assessments

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