[The role of lead as a harmful factor in the manufacture of crystal products]. / K voprosu o roli svintsa kak vrednogo faktora pri proizvodstve izdelii iz khrustalia.

The article deals with research into dust contamination of crystal processing shops, and contains toxicological data related to different lead-containing dusts. It was established that the dust concentrations containing 51 to 66% silicon dioxide was higher in the crystal-cutting shops as compared with other shops. The content of lead in the dust in the composition and crystal processing shops was higher than that in the crystal-cutting shops. Toxicological express-analysis of different dusts performed on cell-cultures revealed that processing-induced crystal dusts were not as toxic as red lead (lead oxide) dusts.
