标准范围

本文件规定了一种通过使用氧化还原染料刃天青测定球形节杆菌脱氢酶活性的抑制来评估需氧悬浮液中固体样品的快速方法。它适用于评估土壤和废料等自然样品中水溶性和固体结合的非挥发性污染物的影响。虽然接触试验不是主要目的，但也可用于试验化学品的影响，如附件所述？C.测试在6？h，因此可用于筛选潜在污染的测试材料。

This document specifies a rapid method for assessing solid samples in an aerobic suspension, by determining the inhibition of dehydrogenase activity of Arthrobacter globiformis using the redox dye resazurin.

It is applicable for assessing the effect of water-soluble and solid matter bounded non-volatile contaminants in natural samples, such as soils and waste materials. Although not the main purpose, the contact test can additionally be used for testing the effect of chemicals, as described in the Annex C. The test yields a result within 6 h and can therefore be used for screening potentially contaminated test material.
