title: [Hygienic evaluation and the effects of toxic factors in the work environment of copper-processing plants].
abstract: The study embraces the shops: metallurgic, electrolysis, production of sulfuric acid and shop 100. Tests are performed on the environmental pollution by dust, sulfur dioxide, chlorine, aerosols of sulfuric acid, carbon monoxide, nitric oxide and dioxide, hydrogen chloride, arsenic (II) oxide (III), selenium, tellurium and metal aerosols: lead, copper, cadmium and zinc. The total concentrations of chemical noxae, generating multicomponent mixtures with one-way effect on the work place, are reckon, and estimation in the Bulgarian Institute of Hygiene and Occupational Health and the Ministry of public health methods. In the same shop is comprised a representative group of workers with paraclinical tests: GOT and GPT activity, content of copper and zinc in blood. The assessment made on the work conditions and the changes already found in the workers lead to a discussion for optimizing the conditions in the new shops for copper production.
