Research to make it index of soil pollution with interaction between soil animals

1)我们用分析电镜观察了污染物在体内的分布。材料是生活在铜污染土壤中的Folsomia candida。2）在日本中部渡濑自然保护区，对铜污染区和清洁区相邻的土壤螨类，特别是甲螨的群落结构进行了研究。由于污染土壤中铜的生物有效性较低，甲螨群落没有明显差异，但总物种丰富度在清洁点较高。结果表明，污染土壤中的弹尾虫多样性低于未污染土壤中的弹尾虫多样性。4）定量分析了石油污染土壤中的大型底栖动物和中型底栖动物（跳虫和螨类），以评价曝气和堆肥等生物修复措施的效果。我们还进行了弹尾（Folsomia candida（Willem））的毒性试验和使用BiOscience Eco Plate的细菌群落分析。这些研究表明，中型底栖动物的数量对石油污染和补救措施更为敏感，一系列研究表明，通气土壤中土壤生态系统的恢复比堆肥土壤中更快。

1) We examined the distribution of the contaminant in the body using analysis electron microscope. Material is Folsomia candida living in copper contaminated soil. Copper was detected from the small intestinal wall and the outside of the body.2) We investigated the community structure of soil mites, especially oribatid mites at Watarase Reservor, central Japan, where copper contaminated site and clean site stand close each other. Due to low bioavailable Cu in the polluted soil, the oribatid mite community was not different, however total species richness was higher in the clean site.3) Collembolan fauna was investigated at the Watarase retarding basin having copper contaminated soil. Comparing the results obtained from polluted and unpolluted sites, it was showed that collembolan diversity in polluted soil was lower than in unpolluted soil.4) We quantified macrofauna and mesofauna (springtails and mites) in oil polluted soil in order to evaluate the effect of bioremediation such as aeration and compost application to the soil. We also conducted toxicity test with springtail (Folsomia candida (Willem)) and bacterial community analysis using BiOLOG Eco Plate. These studies have shown that the number of mesofauna is much more sensitive to oil pollution and remediation, and a battery of these studies showed that the recovery of soil ecosystem is more advanced in the aerated soil than the composted soil.
