Abstract

Determination of mineralogical phases and metal content of respirable dust samples collected at different work sites was performed. Dust was collected by personal samplers with Microsorban membrane filters, and recovery of the dust from the filter was achieved by dissolving the membrane in benzene. Amounts of samples ranged from 1 to 25 mg. Morphological investigations on the samples were carried out by SEM, and the distribution of some selected metals in different minerals was mapped by EDAX. A survey of mineralogical phases was made by X-ray powder diffraction, and quantitative determination of quartz, asbestos, etc., was completed by IR spectroscopy. For the determination of metals, specimens were digested either in acids or in bases depending on the composition of the dust. AAS and ICP-AES were used for these analyses.
