FIELD: agriculture.
SUBSTANCE: method includes measurement of microorganisms test function level in presence and in absence of an analysed sample and calculation of toxicity based on the produced results. Dense samples are exposed to testing (wastes, soils). At the same time testing is carried out without preliminary procedure of producing an aqueous extract of the sample. A test item is a culture of a soil bacillus with dehydrogenase activity, and the test function is its dehydrogenase activity, which is identified using resazurin and recorded using a conventional measurement device for spectrophotometry.
EFFECT: increased efficiency of wastes and soils toxicity identification.
