Working conditions at non-ferrous metallurgical enterprises typically involve exposure to a whole set of harmful chemicals present in occupational air. These chemicals contribute to the development of pathologies in workers, respiratory diseases in particular. Research literature was analyzed using bibliographic databases in order to summarize available information on effects produced by harmful chemicals in workplace air on health of workers employed at mining enterprises. Respiratory diseases such as pneumoconiosis, acute and chronic dust bronchitis prevail among occupational pathologies typical for underground miners. Acute and chronic bronchitis prevail among respiratory diseases as health disorders resulting in temporary disability of miners dealing with non-ferrous metal mining. Huge amounts of dust appear in occupational air at mining enterprises due to drilling, blasting and ore crushing. Priority chemicals found in workplace air in mining industry include several carcinogens such as nickel, lead, formaldehyde, cadmium, and benzo(a)pyrene. There is a unidirectional effect produced by sulfur dioxide, nickel, nitrogen oxides, acrolein, formaldehyde, cadmium, and particular matter on the respiratory organs. The nervous system can be affected by manganese, lead, and selenium; the blood, by nickel, lead, and carbon oxide; the cardiovascular system, by carbon oxide and selenium. Working conditions of underground miners in non-ferrous metallurgy involve intensive exposure to chemicals in occupational air, which create health risks of occupational respiratory diseases and malignant tumors. Diseases of the nervous, immune, cardiovascular systems and the blood are also possible. When planning a set of preventive activities, it is advisable to identify groups of work-related diseases caused, among other things, by a specific chemical factor.
