Three forms of asbestos: amosite, crocidolite, and chrysotile, were assayed for their cytotoxicity and mutagenicity in cell clture. Using embjryonic human intestine derived and adult rat liver derived epitelial cells, the order of toxicity was chrysotile > amosite = crocidolite. Leaching in acid slightly increased the toxicity of amosite and crocidolite and greatly decreased the toxicity of chrysotile. High concentrations of all three asbestos forms were not mutagenic in cultures of rat liver-derived epithelial cells.
