标准范围

ISO 22030:2005描述了在受控条件下测定土壤对高等植物生长和繁殖能力的抑制的方法。推荐两种:芜菁油菜的快速循环变种。Rbr）和燕麦（燕麦）。试验的持续时间应足以包括证明试验植物繁殖能力的慢性终点。通过使用天然测试土壤，例如来自污染场地或修复的土壤，并通过将这些土壤中测试植物的发育与参考或标准对照土壤进行比较，该测试适用于评估土壤质量，特别是土壤作为植物栖息地的功能。可以修改该方法以允许使用慢性植物测定来测试掺入土壤中的化学物质。通过在标准对照土壤中制备测试物质的稀释系列，可以测量相同的终点以评估化学品的慢性毒性。该方法不适用于挥发性物质，即亨利常数或空气/水分配系数大于1的物质，或25°C时蒸汽压超过0.013 3Pa的物质。

ISO 22030:2005 describes a method for determining the inhibition of the growth and reproductive capability of higher plants by soils under controlled conditions. Two species are recommended: a rapid-cycling variant of turnip rape (Brassica rapa CrGC syn. Rbr) and oat (Avena sativa). The duration of test should be sufficient to include chronic endpoints that demonstrate the reproductive capability of the test plants.By using natural test soils, e.g. from contaminated sites or remediated soils, and by comparing the development of the test plants in these soils with reference or standard control soils, the test is applicable to assess soil quality, especially the function of the soil as a habitat for plants.This method can be modified to allow use of the chronic plant assay for the testing of chemicals incorporated into soil. By preparing a dilution series of a test substance in standard control soils, the same endpoints can be measured to assess the chronic toxicity of chemicals.This method is not applicable to volatile substances, i.e. substances for which 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.
