[Evaluation of manganese exposure of workers engaged in the production of manganese ferroalloys].
Manganese concentrations were determined in the ferromanganese plant. In 300 stationary and individual samples manganese was determined by pulse polarography (sensitivity-0.007 mg/m3, precision-10%). The present manganese concentrations are lower than those from earlier studies. Over 50% workers are exposed to manganese concentrations slightly exceeding threshold limit values (TLVs) (0.09-0.43 mg/m3). The other workers are exposed to concentrations several times higher than the TLVs (0.82-1.91 mg/m3). At some workplaces lead concentrations were also determined. TLVs for lead were not surpassed. In result of the use of anodic mass in arc furnaces, the occurrence of polycyclic aromatic hydrocarbons (PAH) is thought possible. Recommendations related to monitoring and selection of workplaces with the same exposures for medical estimation were given. Possible risks for people living near the plant were pointed out.
