ISO 15952:2005规定了一种半静态方法,用于确定污染物对幼蜗牛(通常是Helix aspersa aspersa Müller)生长和存活的影响。使用测试底物(根据研究目的的人工或天然土壤)经由皮肤和消化途径暴露动物,所述测试底物中添加了规定量的以下物质:物质或制剂;以及土壤(受污染或质量未知)或废料。还描述了静态方法。
ISO 15952:2005不适用于挥发性物质,即亨利常数H或空气/水分配系数大于1的物质,或25°C时蒸汽压大于0.013 3Pa的物质。
本试验考虑了试验物质、制剂、土壤或废料可能发生的变化,因为试验混合物在28天试验期内每7天制备和更新一次。
ISO 15952:2005 specifies a semi-static method for the determination of the effects of contaminants on growth and survival of young snails, usually Helix aspersaaspersa 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 or preparations; and soils (contaminated or of unknown quality) or waste materials. A static method is also described.
ISO 15952:2005 does not apply to volatile substances, i.e. substances for which the Henry constant, H, or the air/water partition coefficient is over 1, or for which the vapour pressure is over 0,013 3 Pa at 25 °C.
This test takes into account possible changes in the test substance, preparation, soil or waste material because the test mixture is prepared and renewed every 7 days during the 28-day test period.
