Increasing concentrations of metals in soil have posed a serious threat to the soil environment. The control and evaluation of soil metal hazards demand the establishment of soil ecological criteria, which is mainly based on the obtainment of toxicity thresholds. As the most typical representative of soil-dwelling springtails, Folsomia candida performs numerous essential ecological functions in soil and has been extensively used to investigate metal toxicity effects and thresholds. This review outlined the current state of knowledge on the metal toxicity thresholds to Folsomia candida, including (1) toxicity thresholds of soil metals for the different endpoints, (2) the influence factors of metal toxicity thresholds including the test conditions, the chemical forms of metal, the soil physicochemical properties, aging time and leaching, (3) the bioavailable fractions predicting metal toxicity thresholds, (4) the internal threshold of metals. To conclude, several recommendations for future research are given to obtain the more reliable toxicity thresholds and further supplement the toxicity data of metals to Folsomia candida.
土壤中金属浓度的增加对土壤环境构成了严重威胁。土壤金属危害的控制和评价需要建立土壤生态标准,这主要基于毒性阈值的获取。作为最典型的土壤跳虫代表,Folsomia candida 在土壤中发挥着许多重要的生态功能,已被广泛用于研究金属毒性效应和阈值。本综述概述了目前关于 Folsomia candida 金属毒性阈值的知识状况,包括(1)不同终点的土壤金属毒性阈值,(2)金属毒性阈值的影响因素,包括测试条件、金属的化学形态、土壤理化性质、老化时间和浸出,(3)生物可利用分数预测金属毒性阈值,(4)金属的内部阈值。最后,提出了一些未来研究的建议,以获得更可靠的毒性阈值,并进一步补充 Folsomia candida 金属的毒性数据。
