The ways of entering the environment and harmful effects on human health of copper compounds (copper) and products of their decomposition are considered. Among the chemicals that pollute different objects of the environment, a significant group of toxicants are metals and their compounds. Metals play an important role in the physiological processes of living organisms. However, the ingestion of large quantities of metals into the body leads to poisoning. The subject of research was copper and its compounds. In insignificant quantities it is contained in the cells of almost all human organs. The content of copper is replenished at the expense of food products, especially cereals, peas, mushrooms, meat, and others. Widespread use of copper in industry, agriculture, everyday life requires detailed research in various objects. The method of separation, purification, detection and quantitative determination of coupler compounds in biological objects (seeds of leguminous plants) is proposed. The identification was carried out by qualitative reactions, and the quantitative determination - by the photoelectrocolorimetric method on the basis of the reaction with ditison. The developed method can be determined from 2 to 10 mg of Cuprum in 100 g of the object under study. Detection limit is 0.5 mg.
