U.S. researchers discuss contribution of exposure to endocrine disruptors to metabolic disorders such as obesity and diabetes
Sludge as observatory for chemical exposure
New study proposes to assess sludge as a proxy for human exposure; improving chemical risk assessment of chemicals of emerging concern
Biodegradable plastics may bring degradation and toxicity challenges, say scientists
In an opinion piece published in Waste Management scientists emphasize there is no universal biodegradability of plastics in any ecosystem; waste collection systems need adaptation and toxicity testing improvements; experimental study finds leachates of biodegradable plastic items affect mussel early embryo stages development and adult physiological parameters
Phthalates: impact on leiomyoma growth and mixture risk
Study identifies mono(2-ethyl-5-hydroxyhexyl) phthalate (MEHHP) exposure as high-risk factor for leiomyoma growth on epidemiological and mechanistic level; European biomonitoring of five reprotoxic phthalates demonstrates necessity to integrate mixture risk assessment into regulatory practice; targeted analysis shows migration of five phthalates from polypropylene food packaging

Summer 2023 research snapshot: PFAS in food packaging, food, and potential health impacts
A summary of eight studies; scientists quantify per- and polyfluoroalkyl substances (PFAS) in French fast food packaging; detect eleven PFAS in baking trays from China but not Spain; find PFAS in straws made of paper, bamboo, glass, and plastic; “compostable” service ware can contaminate compost with PFAS; find PFAS in edible oil worldwide; further articles focus on PFAS in drinking water, in Asia, and effects on child respiratory health
ACC responds to BPA & prostate cancer study
American Chemistry Council rejects study linking BPA to prostate cancer; claims study to be based on unreliable human exposure data
