New epidemiological study finds association between high PFOA contamination in drinking water and kidney and testicular cancer, confirming earlier research
EFSA: Draft opinion on NMDR open for consultation
European Food Safety Authority’s (EFSA) draft opinion reviews literature on assessment of non-monotonic dose responses (NMDRs), finds lack of standards for statistical approaches; suggests stepwise approach for ambiguous ‘apparent’ NMDRs; approach applied in two case studies finds no NMDR for bisphenol A (BPA) but does for di(2-ethylhexyl)phthalate (DEHP); open for comments until February 4, 2021
Scientists respond to UNEP’s revised zero draft for a global plastics treaty
Scientists’ Coalition responds to zero draft in preparation for the 4th negotiating meeting (INC-4) on the global treaty to prevent plastic pollution; meeting in Ottawa, Canada from April 23 – 29, 2024; offer evidence- and science-based commentary; highlight the importance of addressing plastic pollution holistically
NGOs request clarification on nanometal biocides in products
Health and Environment Alliance (HEAL) with 12 other NGOs publish an open letter to European Chemicals Agency (ECHA) , request clarification on regulation and risk management of products treated with nanosilver, zinc oxide, copper biocides; antimicrobial resistance, human health effects unclear
Olive leaf polyphenols may be effective against BPA-induced toxicity
Oleuropein and hydroxytyrosol from olive leaves may protect from BPA-induced toxic effects in livers and kidneys
Sources of PFASs exposure in humans
Scientists examine associations between exposure factors and levels of per- and polyfluoroalkyl substances (PFASs) in humans; compare several methods of dietary exposure assessment; food contact articles significantly contributed to PFASs intakes
Carcinogenic potential of BPA
Scientists review carcinogenic properties of bisphenol A; propose that BPA be classified as ‘probably carcinogenic to humans’ due to its tumor promoting properties in the breast and prostate
BPA a risk factor for gut inflammation
Scientists observe BPA exposure in mice decreases anti-inflammatory metabolites produced by gut microbiota, worsens disease symptoms and mortality in disease model of induced colitis
Stakeholders comment on EFSA’s BPA risk assessment
EFSA invites BPA stakeholders for discussion of scientific opinions on risk assessment of BPA; stakeholders from national agencies, NGOs, industry, academia comment
Tracking fluorinated chemicals in the body
Scientists apply radiolabeling to study internal distribution of perfluorocarboxylic acids in mice; find uptake of both long- and short-chain substances in various tissues; method broadly applicable to study PFAS distribution in body and environment
