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

1)用分析电子显微镜观察污染物在体内的分布。材料为生活在铜污染土壤中的念珠叶霉菌。2)调查了日本中部Watarase保护区土壤螨类的群落结构，特别是甲螨群落结构，那里的铜污染场地和清洁场地毗邻。由于铜污染土壤中生物有效铜含量较低，甲螨群落结构基本相同，但物种丰富度相对较高。3)在铜污染土壤的Watarase缓解型盆地调查了弹尾类动物。4)对石油污染土壤中的大型和中型动物(跳虫和螨类)进行了量化，以评价曝气、堆肥等生物修复措施对土壤的修复效果。采用Biolog生态平板进行细菌群落分析，并对其进行了毒性试验。这些研究表明，中型动物的数量对石油污染和修复更加敏感，而且一系列研究表明，充气土壤的土壤生态系统恢复比堆肥土壤更快。

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.
