Despite growing concerns about the potential adverse effects of elevated chromium concentrations in the environment, only a few terrestrial toxicity data are available. Therefore, chronic toxicity of chromium(III) was assessed for Eisenia fetida, Enchytraeus albidus, and Folsomia candida, the three invertebrates for which standard test protocols are available. The 21-day EC(50) for the cocoon production of E. fetida was 892 (679-1110) mg Cr/kg dry weight. Based on the reproduction, a 42-days EC(50) of 637 (355-791) mg Cr/kg dry weight was observed for E. albidus, while for F. candida a 28-day EC(50) of 604 (254-3380) mg Cr/kg dry weight was noted. Although the presented data can be considered a step forward in the assessment of the potential risks of chromium(III) in terrestrial environments, further research is needed to evaluate the influence of soil parameters on the toxicity of chromium and to quantify the effect of aging on bioavailability.

:尽管人们越来越担心环境中铬浓度的升高可能带来的不利影响,但只有少数地面毒性数据可用。因此,对铬(III)的慢性毒性进行了评估,其适用于符合标准测试规程的三类无脊椎动物艾美尼亚艾美氏菌(Eisenia fetida),白鳍金枪鱼(Enchytraeus albidus)和念珠菌Folsomia candida。产费美肠球菌的21天EC(50)为892(679-1110)mg Cr / kg干重。根据繁殖情况,对于白斑埃希氏菌,观察到42天的EC(50)为637(355-791)mg Cr / kg干重,而念珠菌的28天EC(50)为604(254)。记录到-3380mg Cr / kg干重。尽管可以将所提供的数据视为评估陆地环境中铬(III)潜在风险的一步,但仍需要进一步的研究来评估土壤参数对铬毒性的影响并量化老化对铬的影响。生物利用度。
