Propose method to analyze chemical markers of mineral oil aromatic hydrocarbons (MOAH) from printing inks in food packaging; present workflow that includes in silico prediction tools to identify nonvolatile migrates from food packaging; evaluate efficiency and reliability of methodology for non-target identification of volatile substances
International summer school on EDCs
Institut de Biologie Paris-Seine to host summer school on endocrine disruption research on August 25-31, 2019; aims to support PhD and postdoctoral researchers
EDCs, semen quality, and testicular cancer
Editorial in The BMJ discusses parallel trends in semen quality and testicular cancer rates, suggests that EDC exposures could be a risk factor, calls for detailed research on EDCs and male reproductive trends
FDA studies show short-chain PFAS toxicity, metabolite bioaccumulation
Scientists from the U.S. Food and Drug Administration (FDA) publish two studies on 6:2 fluorotelomer (6:2 FTOH); find risk posed by toxicity of 6:2 FTOH previously underestimated, acidic fluorotelomer metabolite bioaccumulates
Surfactants linked to birth defects
New U.S. scientific study associates exposure to quaternary ammonium compounds with transgenerational birth defects in rodents
Microplastics found in human placenta
Research study finds microplastic in placentas of four healthy women, detected both on the maternal and fetal sides of the placenta, membrane in-between; particles could enter the women’s body through oral or respiratory exposure, potential long-term effects for the fetus to be investigated
Agreement on TSCA reform
U.S. House and Senate negotiators agree on draft bill to update TSCA; final votes and signing by U.S. President Obama may follow soon
DEHP disrupts insulin signaling
Scientists find that long-term oral exposure of adult rats to the phthalate DEHP disrupts insulin signaling pathways, resulting in the development of insulin resistance
Scientists explore international bisphenol levels in packaging, food, and urine
Four studies investigate bisphenol (BP) migration from packaging, occurrence in foodstuff, and human urine; report BPA migration from Nigerian epoxy-coated cans into malt drinks; detect four bisphenols in packaged water and honey samples; find BPS in Canadian meat products from 2008 to 2020 suggesting BPS is not a recent phenomenon; measure higher bisphenol alternative levels in Belgian population in 2018 than 2015
Plastic tea bags release billions of particles
Researchers measure micro- and nanoplastics released from plastic tea bags during brewing; find over 14 billion particles released per bag, record dose-dependent behavioral and developmental effects on daphnia
