Ecological Risk Analysis of Soil Pollution Using Soil Animals

土壤污染对土壤动物的生态风险分析研究表明：1）对欧洲跳虫进行了实验室毒性试验，并对日本跳虫进行毒性试验的可能性进行了探讨。本研究以日本的7种弹尾目昆虫为研究对象，探讨了弹尾目幼虫体长的测量方法。利用高清数码显微镜成功地测量了日本跳虫的体长。3）首次在实验室用人工土壤（OECD）对日本跳虫Folsomia candida进行了毒性试验。在Cu和LAS污染较高的土壤中，弹尾虫的生长和存活率下降。4）研究了葡萄糖对弹尾虫生长的影响。将葡萄糖添加到不同含水量的培养基中。5）综述了近年来土壤污染对土壤动物生态风险分析的研究进展。

Studies on analysis of ecological risk to soil animals caused by the soil pollution have shown the following results.1) The European collembolan specie have been used in laboratory toxicity test were reviewed, and the possibilities of the tests with Japanese species were examined. Seven species of Japanese Collembola were considered to be good materials for the test.2) The ways of measuring the body length of young Collembola were examined. The use of HD digital microscope was successful in measuring the body length.3) The first toxicity tests with Japanese Collembola, Folsomia candida, were carried out in laboratory using the artificial soil (OECD). The growth and survival rate decreased in soil higher contaminated with Cu and LAS.4) Effects of glucose on growth of Collembola were investigated. The glucose was added into culture medium with various water contents. The growth was stimulated under high water contents5) Resent studies on analysis of ecological risk to soil animals caused by the soil pollution were reviewed.
