Notes:

(1) Year in brackets: year in which the evaluation was made subsequent to the 1987 supplement 7 working group for agents mixtures or exposures circumstances considered in volumes 43-63 of the monographs number in square brackets: CAS Registry No.

(2) This evaluation applies to the group of chemicals as a whole and not necessarily to all individual chemicals within the group.

Note:
1) Asbestos Cement (A.C) Industry is not listed as carcinogenic. Though 80% of the asbestos fibre consumed goes into this industry.
2) Almost all modern industries are listed as carcinogenic but not Asbestos Cement (A.C)!!
