Arsenic and Diet: Translating Emerging Scientific Evidence into Public Health Policy

Recognition of the significance of diet in human arsenic exposures is increasing. While arsenic is a known toxic chemical, the relationships between lower doses and an array of health outcomes are emerging, complicating estimations of cancer risk and determinations of non-cancer hazard. As a result, policymakers reliant on the results of risk assessment must try to protect vulnerable populations that may be exposed during critical developmental windows in the face of great uncertainty.
