| Abstract |
The biological effects of wool dust and its compenents were studied in 60 primary wool processing workers and in experimental animals to obtain a more precise exposure limit. 870 investigations of dust morphology, particle size distribution, physical, chemical and microbiological composition were carried out. Industrial wool dust is a fibrous, coarse-grained industrial aerosol of composite physical and chemical structure, which in combination with impurities of animal and vegetable origin forms an albumin-antigen complex having pronounced allergic and weak fibrogenic effects on the respiratory system. This latter fact might be accounted for by the low free silica level in respirable dust. It seemed advisable that the current MAC values for wool dust (2, 4 and 6mg/m3) be revised and a single exposure limit of 2mg/m3 (the lowest of the three) established instead, regardless of SiO2 content. Comprehensive and efficient control measures should be introduced to reduce workplace air dust levels and microbial contamination. |
