What is Reproductive Toxicity Category 2?
Substances are classified in Category 2 for reproductive toxicity when there is some evidence from humans or experimental animals, possibly supplemented with other information, of an adverse effect on sexual function and fertility, or on development, and where the evidence is not sufficiently convincing to place the …
What is the difference between a Group 2A and a Group 1 carcinogen?

What are the criteria for Category 1b carcinogenicity?
Positive results for one species in at least two independent studies, or a single positive study showing unusually strong evidence of malignancy may also lead to Category 1B.
How are carcinogens classified according to strength of evidence?
Carcinogen classification involves two interrelated determinations: evaluation of strength of evidence and consideration of all other relevant information (weight of evidence analysis). Carcinogens are categorized as either known/presumed carcinogens (Category 1) or suspected carcinogens (Category 2).
