Workers in all the technological areas of lead processing industry are affected by industrial aerosols and hazardous microclimate conditions. The aerosols are of compound compositions containing large quantities of lead, zinc, cremnium, copper, cadmium, arsenic and other elements. The content of lead and concomitant metals in the air in different parts of the lead producing shop varies significantly depending on the technological processes' specificity. The degree of concentration in different parts of the shop will also depend on the architectural design features of the working area as well as on the locality of the lead shop in the production site. The unfavourable microclimate conditions are determined by the technological process specificity, the area's climatic characteristics and the presence of vast embrasures and openings in the shop building. The labour improving measures taken for several years proved to be ineffective. The multistage technology, inadequacy of some technological processes, insufficient hermetization and ventilation cannot exclude the workers' immediate contact with toxic substances. The significant pollution of the working zone area with toxic substances is just another factor which may affect the workers' health conditions.
