Summary
Classified by IARC as Group 2B — possibly carcinogenic to humans. Evidence is limited. (Vol 115, 2018)
What's not established
This classification means the evidence is limited: either limited evidence in humans, or sufficient evidence in animals without enough human data. It does not establish that this factor causes cancer in people, a safe exposure threshold, or your personal risk from a given level of exposure.
