OEH Seminar: Complementarity of hazard and risk assessments in recent IARC reviews of pesticide carcinogenicity

​Note: This is an open invitation, and may be forwarded to interested parties.

The recent publication of a hazard assessment by the International Agency for Research on Cancer (IARC) that focused on various pesticides resulted in considerable discussion and debate. In particular, the review of human, experimental and mechanistic data resulted in glyphosate (a herbicide that is widely used globally) being classified as a probable carcinogen. The evidence and methodology upon which the IARC assessment was based will be summarized. Implications of the conclusions and how the results differ from and complement other assessments (e.g., risk assessments) will be reviewed.  Research and policy implications will also be discussed.

Presenter: Dr.  John McLaughlin
