How and why to close the exposure assessment gap

~ PRHE

Quantitative risk assessments underpin most of our federal regulations related to chemicals. Therefore, it is important to understand how and why risk assessments can go astray. Risk assessment brings together concepts of hazard (the potential for a chemical to result in an adverse health outcome, such as carcinogenicity) and exposure. Combining multiple sources of information … Continue reading How and why to close the exposure assessment gap

The fox shouldn’t guard the hen house

~ Swati Rayasam

EPA says it must consider the perspective of multiple stakeholders when regulating, but the chemical industry can play an outsized role in Agency rulemaking. For example, when people paid by industry, through grants, contracts, or as employees, are appointed to EPA scientific advisory committees, this financial conflict of interest (financial COI) can lead to weaker … Continue reading The fox shouldn’t guard the hen house
