ABSTRACT
A total of 100 miners exposed to antimonate dust concentrations considerably exceeding the MAC were examined, and 16% of the subjects appeared to have chronic bronchitis. No pneumoconioses were diagnosed. The chronic bronchitis was characterized by mild slow course with I degree of ventilation disturbances. Antimonate ore turned out to induce toxic effects and activate some protective mechanisms: phagocytosis, immune response, inhibition of proteases.

Hygienic, clinical, epidemiologic studies in primary woodworking and chipboard production workers showed that exposure to occupational hazards (wooden dust, formaldehyde and other chemicals of wooden origin) results in frequent allergy and irritation of upper respiratory tract and skin. High oncologic risk among woodworking production employees assigns the industry to a group with oncologic jeopardy. MAC for wooden dust should be corrected taking into account the chemicals (phenol, formaldehyde, furans et al.) content.
