水质.难溶物质、挥发化合物、金属和废水的藻类生长抑制试验指南

[中文适用范围]： 本国际标准提供了 ISO 8692 和 ISO 10253 中描述的方法未涵盖的程序，用于测试难以抑制藻类生长的物质。 该指南涵盖的主要主题是测试用测试物质的制备方法以及进行适当测试所需的程序。 本指南涵盖以下测试物质： a) 难溶的纯有机化合物； b) 难溶的有机物质混合物； c) 难溶性无机材料； d) 挥发性物质； e) 含有水和沉积物的废水和环境样品； f) 有色和/或浑浊的样品； g) 重金属化合物。 涵盖以下添加方法： ——直接； ——色散； ——水溶性和水可容纳的部分。 其中包括一些与分析程序和结果解释相关的指南。 参考书目中给出了描述困难物质测试背景的文件参考。 [外文原描述]： ISO 14442:2006 provides procedures, not covered by the methods described in ISO 8692 and ISO 10253, for testing difficult substances for inhibition of algal growth. The main subjects covered by ISO 14442:2006 are the methods for preparing the test substance for testing and the procedures needed to carry out an appropriate test. The following test substances are covered by this guideline: poorly soluble pure organic compounds; poorly soluble mixtures of organic substances; poorly soluble inorganic materials; volatile substances; waste waters and environmental samples containing water and sediments; coloured and/or turbid samples; compounds of heavy metals. The following methods of addition are covered: direct; dispersion; water-soluble and water-accommodated fractions. Some guidelines related to the analytical procedures and to the interpretation of the results have been included.
