Scientists calculate US health care costs caused by a well-studied subset of endocrine-disrupting chemicals (EDCs) in plastics; estimate exposure cost $250 billion in 2018, equivalent to 1.22% of Gross Domestic Product; recommend addressing chemicals of concern in global plastics treaty to reduce disease burden and costs
Microplastics impacts on the reproductive system and offspring
Scientists report human-relevant polystyrene (PS) microplastic concentrations change mice placental metabolism; show nanoplastics have variable effects on placental enzymes using simulations; find pre- and postnatal PS microplastic exposure affects male mice testis development and fertility; recommend future research to analyze multigenerational effects
Scientists investigate chemicals in plant-based materials
Review summarizes chemicals present in and migrating from food contact articles made with wood, bamboo, and other plant-based materials; researchers identify and quantify 25 non-volatile compounds from bamboo, palm leaf, wood and wheat pulp dishes; tentatively identify 115 non-volatile chemicals in extracts from six plant fiber/plastic composites; detect phthalates in Brazilian dry foods in cellulose-based packaging
Hazard prioritization of printing inks and adhesives substances
Scientific study performs hazard prioritization on chemicals in printing inks and adhesives applied to plastic food packaging; uses publicly available “substances of concern” lists and an in silico tool; identifies 636 high and 1024 medium priority substances of which 696 ranked as “very high priority substances” by experts
Studies assess composition and safety of chemicals in recycled HDPE
Scientists analyze volatile compounds in recycled high-density polyethylene (HDPE); detect 53 chemicals in two post-consumer HDPE milk bottles including plastic additives and non-intentionally added substances (NIAS); risk assessment shows samples do not comply with plastic food packaging regulation; report re-granulation process in mechanical recycling to remove most but not all odor and volatile organic compounds
Stakeholders discuss waste management challenges of plastics
Publications from government, academia, civil society organizations, and consultancies paint problematic picture of a circular plastics economy; plastic packaging waste per person found to increase over last decade; low percentage of plastic produced is effectively recycled; pyrolysis (a type of chemical recycling) of plastics produces 9x more emissions than mechanical recycling; “biodegradable” and “compostable” plastics found to not break down in home compost systems

REACH as possible innovation driver
ChemSec declares combination of hazard- and risk-based elements as world-leading regulatory example, criticizes halt in addressing substances from the Candidate List
Global Food Contact Conference 2022: updates from the Americas
Smithers conference covers global developments in food contact regulations and materials; speakers on day one review recent and upcoming changes to food packaging regulations in the US, Canada, and the South American trade bloc Mercosur
Phthalates and their replacements measured in US fast food
Researchers measure phthalates or phthalate-replacing plasticizers in 100% of fast food samples from McDonald’s, Burger King, Pizza Hut, Domino’s, Taco Bell, and Chipotle restaurants in the US; seen as first published data of plasticizer DEHT detected in fast food
