标准摘要
[中文适用范围]： 本国际标准规定了基于 14 天和/或 28 天后的存活和生长抑制来测定整个沉积物中阿兹特克幼虫毒性的方法。 该方法适用于 a) 受污染的整个淡水沉积物样品，b) 化学、工业或城市污泥，或可能与新鲜沉积物结合的其他固体废物，以及 c) 添加到干净沉积物中的化学品或制剂。 [外文原描述]： ISO 16303:2013 specifies a method for the determination of toxicity to young Hyalella azteca in whole sediment based on survival and growth inhibition after 14 d and/or 28 d. The method is applicable to a) samples of contaminated whole freshwater sediment, b) chemical, industrial, or municipal sludge, or other solid wastes that may combine with freshwater sediments, and c) chemicals or preparations spiked into clean sediment. ISO 16303:2013 is applicable to the testing of sediment samples from the freshwater environment. Hyalella azteca can be used in the testing of brackish waters up to a maximum of 15 ?, with careful acclimation. ISO 16303:2013 is not applicable to the testing of sediment samples from the marine and estuarine environment with a salinity of > 15 ?. This method is a 14 d and/or 28 d survival-and-growth test applicable to the sediment sample types described above.
