Ecological Systems and Devices Annotation << Back Chemical elements in dust discharge of electrical engineering enterprises as source pollution of the environment Yanin E.P. The industrial dust discharge of the electric engineering enterprises is a key source of many chemical element in the environment. Normally, geochemical signature of on individual enterprise is also individual, as reflected by different concentration levels for individual elements and, less frequently, by pollutants specific for a given enterprise.
