Title Synergistic effects of mica dust and resins in the manufacture of micanite products
Original title K voprosu o kombinirovannom dejstvie pyli sljudy i smol, primenennyh v proizvodstve mikanitovyh izdelij [in Russian]
Bibliographic information July 1976, No.7, p.33-37. Illus. 4 ref.
Abstract Brief report of an occupational health survey in a factory producing micanite components, etc. (presence in workplace air of phlogopite, muscovite, shellac and alkyd resins (glyptals); 7 cases of pneumoconiotic changes in 82 cases studied), followed by results of experiments in white rats: inhalation of the 4 above-mentioned substances (separately) caused discrete pneumoconiosis. Combined inhalation of mica dust and resin, however, produced an inhibiting effect of the shellac and alkyd resin on the course of the pneumoconiosis produced by the mica, with significant potentiation of the toxic and sensitising effects. A TLV of 2mg/m3 is recommended for simultaneous concentrations of these dusts.
