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

我们用分析电子显微镜检查了污染物在体内的分布。材料为生活在铜污染土壤中的念珠菌。从小肠壁和体外检测到铜。2)研究了日本中部Watarase水库土壤螨的群落结构，特别是铜污染场地和清洁场地相邻的土螨。由于受污染土壤中生物可利用铜含量较低，甲螨群落差异不大，但总物种丰富度在清洁地较高。3)在铜污染土壤的Watarase缓凝盆地调查了collebolan动物群。结果表明，污染土壤中collbolan的多样性低于未污染土壤。4)定量分析了石油污染土壤中大型动物和中型动物（弹尾虫和螨虫）的数量，评价了生物修复（曝气和堆肥）对土壤的影响。用假丝酵母菌（Folsomia candida, Willem）进行毒力试验，用BiOLOG生态板进行菌群分析。这些研究表明，中游动物的数量对石油污染和修复更为敏感，并且这些研究表明，在曝气土壤中土壤生态系统的恢复比堆肥土壤更早。

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.
