(a) Year in brackets: year in which the evaluation was published 
    subsequent to  the Supplement  7  Working  Group  for agents, 
    mixtures and  exposure  circumstances considered in Volumes 43-58 
    of the Monographs.

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

(c) There  is  also conclusive evidence that these agents have a protective 
effect against cancers of the ovary and endometrium.

(d) Overall evaluation upgraded from 2B to 2A with supporting evidence from 
other relevant data.

(e) Overall  evaluation upgraded from 3 to 2B with supporting evidence from  
other relevant data.
