中文名称：土壤质量 用球形节杆菌脱氢酶活性固体样品的接触试验
英文名称：Soil quality — Contact test for solid samples using the dehydrogenase activity of Arthrobacter globiformis
发布日期：2024-05
标准范围
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.
