标准摘要
[中文适用范围]： 本国际标准规定了在24小时至48小时暴露条件下，毒物对Brachionas plicatilis的致死效应测定方法。该方法适用于以下情况：a)可溶性化学物质或可在测试条件下维持稳定悬浮液或分散液的毒物；b)工业废水或生活污水，经过沉淀、过滤或离心处理后适当；c)海水或河口区水；d)沉积物提取液/渗滤液。 [外文原描述]： ISO 19820:2016 specifies a method for the determination of the lethal effects of toxicants to Brachionus plicatilis after 24 h or 48 h exposure. The method is applicable to the following: a) chemical substances which are soluble or which can be maintained as a stable suspension of dispersions under the conditions of the test; b) industrial or sewage effluents, treated or untreated, if appropriate after decantation, filtration, or centrifugation; c) marine or estuarine waters; d) sediment elutriates/eluates.
