A Review of Carcinogenicity Studies of Asbestos and Non-Asbestos Tremolite and Other Amphiboles
Non-Asbestos Tremolite Amphiboles Carcinogenicity Study
2011/11/11
Experimental animal studies comparing asbestos and non-asbestos varieties of tremolite indicate tremolite asbestos is markedly more carcinogenic. By direct analogy, the differences in carcinogenicity ...
