||Concentrations of carcinogenic metals (cadmium, nickel) and metalloids (arsenic) were measured in workplace air during heavy metals refining processes. The tests were conducted in two large Polish plants, a copper smelter and a non-ferrous metals smelter, at workstations for the refining of copper, zinc, cadmium, lead and silver and the production of nickel sulfate and selenium. The presence of arsenic in the workplace air was found in both plants. Exposure to cadmium occurred only in the non-ferrous metals smelter. The highest exposure was found at workstations in the lead and cadmium refining processes. The presence of nickel was found only at workstations with nickel sulfate production. The results highlight the need for routine measurements of arsenic concentrations at all workstations in the production of metals with a high degree of purity.
