Studies discuss EDC sources, exposure, and human health effects

Scientific studies investigate human endocrine-disrupting chemical (EDC) exposures and effects; Canadian study finds bisphenols migrate from baby bottles and sippy cups; reviews report of widespread presence of bisphenols, parabens, and benzophenones in human breast milk and addresses current misunderstandings about the impacts of EDCs on child health

2021 FPF Workshop: Sharing recent scientific research

On the first day of the Food Packaging Forum’s annual workshop, speakers discuss their latest scientific research projects covering food contact chemical migration, human biomonitoring, mixture effects, threshold levels, microplastics, and impacts on reproduction

Study finds UV stabilizers with endocrine-disrupting potential in plastics

Research study identifies 8 of 13 benzotriazole UV stabilizers (BUVSs) as endocrine disruptors; finds 8 of 9 tested BUVSs in polyolefin packaging

Study links phthalate exposure and thyroid function in humans

Scientific study investigates effect of plasticizer exposure during pregnancy on thyroid function; outcomes suggest several phthalate metabolites disrupt thyroid hormone levels; finds association of phthalate-alternative DINCH with thyroxine levels

Bisphenols in thermal paper extracts and drinking bottle migrates

Scientific studies analyze bisphenol content in thermal papers and migrates from reusable drinking bottles; of 14 analyzed bisphenols 4 detected in thermal receipts and 3 in bottles migrates at low concentrations; dishwashing but not handwashing prior to use reduces bisphenol A (BPA) leaching from Tritan

Study finds microplastics induce reproductive toxicity in male mice

Study investigates reproductive toxicity of environmental concentrations of polystyrene (PS) microplastics to male mice; further examines underlying molecular mechanism; study is first to find long-term PS microplastic exposure affects sperm quality and testosterone levels in mice

Studies investigate impacts of EDC exposure during pregnancy

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

Web-based intervention reduces EDC exposure levels

Scientists design a web-based behavioral intervention to reduce endocrine disruptor exposure in mothers with young children; involves educational videos and games to affect diet, product use, and other habits; study finds one-month intervention significantly lowers urinary concentration of bisphenol A, triclosan, parabens, and phthalate metabolites

Studies investigate plastic packaging use, EDCs, and reproductive health

Recent research articles look at relationship between endocrine disrupting chemicals (EDCs) from packaging and human reproductive health; find no relationship between a woman’s reported use of plastic food packaging and pregnancy duration and birthweight; identify potential non-monotonic dose-response relationship between di-2-ethylhexyl phthalate (DEHP) exposure and woman’s reported infertility

EFSA determines titanium dioxide not safe as food additive

European Food Safety Authority (EFSA) releases new assessment of titanium dioxide as a food additive, could not rule out genotoxicity; change in opinion from last assessment in 2016; announcement does not affect food contact materials
