土质.污染物对蚯蚓的影响.第1部分:测定对赤子爱胜蚓(Eisenia fetida/Eisenia andrei)剧烈毒性

[中文适用范围]： ISO 11268的这一部分规定了评估土壤栖息地功能和确定土壤污染物和化学物质通过皮肤和食物吸收对赤子爱胜蚓/安氏爱胜蚓的急性毒性的方法之一。 它适用于质量未知的土壤和土壤材料，例如来自污染场地、改良土壤、修复后的土壤、农业或其他相关场地以及废物材料。 使用标准土壤，优选指定的人造土壤基质来评估物质的影响。 对于受污染的土壤，在测试土壤和对照土壤中确定对生存的影响。 根据研究的目的，对照和稀释基质（污染土壤的稀释系列）应该是与待测土壤样品相当的未污染土壤（参考土壤）或标准土壤（例如人造土壤）。 提供了有关如何使用此方法在温带和热带条件下测试化学品的信息。 该方法不适用于挥发性物质，即H（亨利常数）或空气/水分配系数大于1，或25℃时蒸气压超过0.0133 Pa的物质。 该方法没有考虑测试过程中物质或污染物可能发生的降解。 [外文原描述]： 1 Scope This part of ISO 11268 specifies one of the methods for evaluating the habitat function of soils and determining the acute toxicity of soil contaminants and chemicals to Eisenia fetida/Eisenia andrei by dermal and alimentary uptake. It is applicable to soils and soil materials of unknown quality, e.g. from contaminated sites, amended soils, soils after remediation, agricultural or other sites concerned, and waste materials. Effects of substances are assessed using a standard soil, preferably a defined artificial soil substrate. For contaminated soils, the effects on survival are determined in the test soil and in a control soil. According to the objective of the study, the control and dilution substrate (dilution series of contaminated soil) should be either an uncontaminated soil comparable to the soil sample to be tested (reference soil) or a standard soil (e.g. artificial soil). Information is provided on how to use this method for testing chemicals under temperate as well as under tropical conditions. The method is not applicable to volatile substances, i.e. substances for which H (Henry's constant) or the air/water partition coefficient is greater than 1, or for which the vapour pressure exceeds 0,013 3 Pa at 25 °C. This method does not take into account the possible degradation of the substances or contaminants during the test.
