Jl. Levin et al., AN INDIVIDUAL WITH A MAJORITY OF FERRUGINOUS BODIES FORMED ON CHRYSOTILE CORES, Archives of environmental health, 50(6), 1995, pp. 462-465
A 59-y-old man was exposed to chrysotile asbestos while rebuilding clu
tches. Analytical electron microscopy showed a chrysotile core in 72%
of the ferruginous bodies from lung tissue. Long, uncoated chrysotile
fibers were also present. Sufficient exposure to long chrysotile in jo
bs such as this appears to allow the majority of ferruginous bodies to
be formed on chrysotile, an exception to the rule that most ferrugino
us bodies form on amphibole cores.
