[Experimental study on risk factors of pneumoconiosis caused by dust in the industry of new construction materials containing glass and coal waste].

The study compared cytotoxicity and fibrogenic ability of quartzitic dust to that appearing at 3 sites of light building filler production based on ground glass or clinker. Obtained results prove possible pneumoconiosis development caused by exposure to such dust types, especially in the production using ground glass. The MAC in this type of production is 2 mg/cu m, for the dust in production using clinker the MAC is 4 mg/cu m.
