Exposure to PFAS chemicals doubles the odds of a prior cancer diagnosis in women

A new study shows a clear association between exposure to certain PFAS (per- and poly-fluoroalkyl substances) and phenol (including BPA) chemicals and a previous cancer diagnosis in women from the National Health and Nutrition Examination Survey (NHANES). The study was conducted by researchers in NIEHS-funded P30 centers from UC San Francisco (UCSF), University of Southern … Continue reading Exposure to PFAS chemicals doubles the odds of a prior cancer diagnosis in women

How and why to close the exposure assessment gap

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

PFAS and chemicals used in plastics associated with increased risk of poor pregnancy outcomes

Chemicals used in plastic production and PFAS are widespread in Bay Area pregnant women and are associated with an increased risk of poor pregnancy outcomes including gestational diabetes, pre-eclampsia, and hypertension, according to UCSF researchers. In a new study published in the July 19, 2023, Environmental Health Perspectives, UCSF researchers with the Program on Reproductive … Continue reading PFAS and chemicals used in plastics associated with increased risk of poor pregnancy outcomes

CRAs can help EPA more accurately estimate risks from toxic chemical exposures

When a nail salon worker heads home after work, she’s probably carrying more than her paycheck. She is also carrying phthalates — a class of toxic chemicals that contaminates people via nail polish, cosmetics, cleaning supplies, plastics, and food. One nail salon worker is exposed to multiple chemicals from many different sources, yet regulators like … Continue reading CRAs can help EPA more accurately estimate risks from toxic chemical exposures

Makers of PFAS ‘forever chemicals’ covered up the dangers

Widely used in clothing, household products and food, they resist breaking down in the environment The chemical industry took a page out of the tobacco playbook when they discovered and suppressed their knowledge of health harms caused by exposure to PFAS (per- and polyfluoroalkyl substances), according to an analysis of previously secret industry documents by … Continue reading Makers of PFAS ‘forever chemicals’ covered up the dangers

The fox shouldn’t guard the hen house

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

EPA moves to further limit deadly methylene chloride

EPA today issued a proposed rule that would further limit the deadly chemical methylene chloride, proposing to ban the use of methylene chloride for all consumer uses and most industrial uses. EPA says the banned uses account for 52% of current methylene chloride production. In response, Tracey J. Woodruff, PhD, former EPA senior scientist and … Continue reading EPA moves to further limit deadly methylene chloride
