标准摘要
[中文适用范围]： 本文件规定了一种测试，该测试可在强制有氧和无氧条件下模拟土壤和类土壤材料中无机物质（如重金属、砷和磷）和有机物质的原位可用浓度。然后可以根据这些可用浓度估计毒性。本文件中描述的测试旨在测量土壤和类土壤材料中无机和有机物质的释放，以及产生用于后续生态毒理学测试的洗脱液。有关生态毒理学测试，请参阅 ISO 15799 和 ISO 17616。随后可根据现有标准方法通过物理、化学和生态毒理学方法对获得的洗脱液进行表征。该测试不适用于在环境条件下易挥发的物质。该程序不适用于干物质含量低于 33% 的材料。该测试主要用于常规和控制目的，不能单独用于描述土壤的所有浸出特性。需要进行额外的浸出测试才能实现该扩展目标。本文件不涉及与健康和安全相关的问题。它仅确定第 4 条中概述的浸出特性。 [外文原描述]： This document specifies a test with which in situ available concentrations of inorganic substances (such as heavy metals, arsenic and phosphorus) and organic substances in soil and soil-like materials can be simulated under forced aerobic and anaerobic conditions. The toxicity can then be estimated based on these available concentrations. The test described in this document aims to measure the release of inorganic and organic substances from soil and soil-like material as well as to produce eluates for subsequent ecotoxicological testing. For ecotoxicological testing, see ISO 15799 and ISO 17616. The eluate obtained can subsequently be characterized by physical, chemical and ecotoxicological methods in accordance with existing standard methods. The test is not suitable for substances that are volatile under ambient conditions. This procedure is not applicable to materials with a dry-matter-content ratio lower than 33 %. This test is mainly aimed at being used for routine and control purposes, and it cannot be used alone to describe all leaching properties of a soil. Additional leaching tests are needed for that extended goal. This document does not address issues related to health and safety. It only determines the leaching properties outlined in Clause 4.
