Abstract:
Lavage material was collected from 12 individuals whose work history included working in a cement manufacturing facility. The manufacturing processes of the facility included the use of crocidolite and chrysotile asbestos. Lavage material was prepared via digestion procedure and then analyzed for the presence of ferruginous bodies by light microscopy and for uncoated asbestos fibers by analytical transmission electron microscopy. A comparison was made as to the sensitivity between two analytical methods for linking a past exposure to a specific type of asbestos. The use of analytical transmission electron microscopy for identification of core material in the ferruginous bodies as well as for quantification of the uncoated asbestos fibers increased the sensitivity of the information obtained from lavage samples as necessary for confirming exposure in the past to specific types of asbestos.
