[Fly ash and its biological effects. I. Production, utilization and physico-chemical properties of fly ash].
Med Pr. 1988; 39(5):338-46.MP

Abstract

The paper includes the results of Part I of the studies designed to evaluate occupational risk of power engineering workers, i.e. people employed in plants producing fly-ashes, as well as those working in lightweight concrete plants where fly-ashes are applied as raw materials. The authors have found out that fly-ashes included mainly quartz, orthoclase and mullite. In dust samples, particles of fibrous structure have been found (probably--mullite). The content of free crystalline silica came to 31.6% in total dust and 8.9% in respirable dust. Fly-ashes contained:--naturally radioactive elements K40, Ra226, Th228 (maximum values were, respectively: 1070 Bq/kg, 222 Bq/kg, 142 Bq/kg of dust),--aromatic hydrocarbons (benzene-soluble fraction) in the amount of 0.001 to 0.003 microgram/mg, as well as admixtures of heavy metals in amounts varying largely. The dust concentrations at workplaces ranged from 1 mg/m3 to 200 mg/m3, depending on the type of work (inspection, repair of boilers). The results demonstrate that in the working environment of power engineering and lightweight concrete plants there occur agents of potentially fibrogenic and cancerogenic properties.
