title: [Catalytic properties of dust as criteria of its occupational hazards].
abstract: The catalytic properties of fire clay (kaolin) and mullet dusts versus quartz, asbestos, and coal ones were studied. Kaolin and mullet were found to have different catalytic capacities mainly of forming free radicals. The dust of kaolin increased the level of superoxide anion radical and hydrogen peroxide in the granulocytic suspension and H2O2/O2 ratio to a lesser extent than that of mullet and quartz. Differences in the catalytic capacity of the examined dusts confirm the findings from the investigations of their effects on plasma lipid peroxidation (LPO). Kaolin and quartz were the least in elevating LPO. As compared with kaolin and quartz, the effects of mullet and asbestos were 2.5 and 6.5 higher, respectively. The substances were different in their genotoxicity.
