标准摘要
[中文适用范围]： 本文件规定了一种半静态方法，用于确定污染物对幼年蜗牛（通常是 Helix aspersa aspersa Müller）生长和生存的影响。 使用测试基质（根据研究目的的人造或天然土壤）通过皮肤和消化途径暴露动物，其中添加规定量的以下物质： ——物质、混合物或制剂； ——土壤（受污染或质量未知）或废料。 该测试考虑了测试物质、制剂、土壤或废料中可能发生的变化，因为在 28 天的测试期间每周都会制备和更新测试混合物。 除了半静态方法之外，还可以实现静态方法（可选）。 该方法在附录 A 中描述。 该方法不适用于空气/土壤分配系数大于 1 的物质，或 25 °C 时蒸气压超过 300 Pa 的物质。 [外文原描述]： This document specifies a semi-static method for determining the effects of contaminants on growth and survival of young snails, usually Helix aspersa aspersa Müller. The animals are exposed via the cutaneous and digestive route using a test substrate (artificial or natural soil according to the objective of the study) to which defined amounts of the following are added: - substances, mixtures or preparations; - soils (contaminated or of unknown quality) or waste materials. This test takes into account the possible changes in the test substance, preparation, soil or waste material because the test mixtures are prepared and renewed every week during the 28-day test period. A static method may be implemented in addition to the semi-static method (optional). This method is described in Annex A. This method does not apply to substances for which the air/soil partition coefficient is greater than one, or to substances with vapour pressure exceeding 300 Pa, at 25 °C.
