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
Five studies examine effects following exposure to endocrine disrupting chemicals (EDCs) during pregnancy; report association between bisphenol A (BPA) exposure and preterm birth and decreased gestational age, especially upon exposure in third trimester of pregnancy; find contradicting results on fetal growth impacts from BPA; intake of synthetic progesterone by pregnant women found to double cancer risk of their offspring; propylparaben exposure found to alter mammary gland structure in mice
Experimental study examined uptake and effects of polystyrene microplastic on human intestinal cells and on mice; finds no relevant acute health risks to mammals
Bisphenol A is widely used in plastic consumer products, including food packaging. It likely has been the most controversial substance of the last decade. The Food Packaging Forum provides a background article of application, toxicity and regulation of BPA as well as giving a summary of the most debated issues in the research of BPA.
American Chemistry Council rejects study linking BPA to prostate cancer; claims study to be based on unreliable human exposure data
Scientists explore potential impacts of microplastics on human intestine ecology; microplastics may drive unhealthy changes in the gut microbiome; authors highlight importance of assessing human microplastics exposure and hazards for the gut
Scientists quantify per- and polyfluoroalkyl substances (PFASs) and their precursors in microwave popcorn bags sampled in Europe, Americas, Asia; short-chain PFASs prevalent in Europe and Americas, long-chain PFASs in Asia
New study links BPA exposure in pregnancy to oxidative stress in mother and offspring, similar findings in both human association study and animals testing study
Silicones are an exclusive class of polymers broadly used in food contact materials. Due to their versatile properties, they are applied as fluids, rubbers and resins.
Agence France-Presse reports on investigation of environmental causes of breast cancer; phthalates, BPA and pesticides found in all girls participating in study
