The asbestos found in the Penokee Hills is amphibole.
Several studies have investigated the effects of asbestos on fish (Batterman and Cook 1981, Belanger et al. 1990, Belanger et al 1986, Woodhead et al. 1983). The findings indicate that asbestos concentrations on the order of 106 to 108 fibers/L may cause epidermal lesions, epithelial hypertrophy, kidney damage, decreased orientation and swimming ability, degradation of the lateral line, reduced growth, and increased mortality in fish. Undisturbed, non-friable (not easily crumbled) asbestos has been found to be relatively harmless (Garcia and Salzwedel 1995, Montoya et al 1985).
