Abstract
The purpose of this study was to determine the presence and concentration of asbestiform minerals in seven (7) rock quarries. Generally, each of the participating quarries submitted samples of its product for analysis on a weekly basis for approximately twelve (12) weeks. A representative aliquot was obtained from each sample and consecutive weekly samples were composited. Analysis of the samples was performed on a transmission electron microscope, using morphology and selected area electron diffraction patterns as primary criteria, with the aid of non-dispersive x-ray spectra on difficult on selected fibers. Each fiber observed was categorized and sized. The size data was used to compute mass estimates for chrysotile and amphibole fibers. The concentration of chrysotile or amphibole was computed on a weight percent basis. Several of the quarries were found to contain asbestos.
