B2 = EPA weight-of-evidence category, “probable human carcinogen, sufficient evidence in animals and inadequate or no evidence in humans.”

C = EPA weight-of-evidence category, “possible human carcinogen” rating.

D = EPA weight-of-evidence category, “not classifiable as to human carcinogenicity,” usually due to inadequate data.

2B = International Agency for Research on Cancer, World Health Organization (IARC) category, the agent (mixture) is possibly carcinogenic to humans.

X = Adverse effect demonstrated.
