HYGIENE FACTORS OF THE AIR ENVIRONMENT AND THEIR ROLE IN THE
FORMATION OF CANCER RISK IN HYDROMETALLURGICAL COPPER
PRODUCTION

Hygienic assessment of working conditions in modern hydrometallurgical copper production has been
carried out, the assessment in formation of carcinogenic risk of the workers employed in a
hydrometallurgical complex of copper-containing ores in comparison with pyrometallurgical processes
has been made. It is shown that in copper mining, the main factor causing a carcinogenic risk is
inorganic compounds of cadmium and lead. The greatest predictive values of carcinogenic risk for
metallurgical shops professions are observed in pyrometallurgical production, rather than in
hydrometallurgical production, due to the difference in the equipment used. The main measure to reduce
the carcinogenic hazard in obtaining cathode copper by the hydrometallurgical method should be the
introduction of effective ventilation systems.
