[Fly ash and its biological effects. 3. Exposure to dust of workers in the energy-generating industry (power plants and thermoelectric power stations)].
An evaluation of exposure to dust of workers employed at typical work-stands in power industry plants was made. Mean concentrations of respirable dust determined at 14 different work-posts range from 0.45 to 8.95 mg/m3, and of total dust from 1.55 to 85.0 mg/m3. Mean content of free crystalline silica in dust samples is less than 10%. At the work-stands where ash dust was encountered, the presence of respirable fibres at concentration below 0.2 fibre/cm3 was observed. In all ash samples alpha-quartz and mullite were found: in some of them also kaolinite and orthoclase were traced. Only at five out of all 14 work-stands examined mean concentration of respirable dust was lower than the hygienic standard value.
