Abstract |
In grey iron and steel foundries, an average of 93,950 microorganisms was found in 1m3 of air. Mesophilic bacteria predominated over micromycetes and actinomycetes. Microbial contamination ranged from 23,480 organisms/m3 on casting floors to 361,130 per m3 in cellars where moulding mixtures were prepared. 11 species of mesophilic bacteria and 40 species of fungi and yeasts were identified. Microbial contamination came from foundry raw materials and water, and was aggravated by insufficient ventilation. Dust (containing free Si02) that had settled on metal structures at breathing zone level contained the most varied species (8 types of mesophilic bacteria and 61 types of micromycetes). The microorganisms included saprophytic, facultatively pathogenic and toxigenic species. |
