Soil quality - Contact test for solid samples using the dehydrogenase activity of Arthrobacter globiformis (ISO/FDIS 18187:2024); German version FprEN ISO 18187:2024
Abstract
ISO 18187:2016 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 of natural samples, such as soils and waste materials. The test yields a result within 6 h and can therefore be used for screening potentially contaminated material.
