Two studies investigating chemicals from retail plastic food contact articles find considerable variability in complexity, with subsequent effects on cell-based tests of hormone disruption; many more chemicals measured from PVC and polyurethane than other polymers though the chemical mixtures from majority of the plastic samples are hormone disrupting; further evidence of PVC and PUR can interfere with GPCR-based cell communication
Developing the science-policy panel on chemicals and pollution
National delegations meet in Thailand to discuss the objectives and responsibilities of the new science-policy panel on chemicals, waste, and pollution prevention; in run up to the meeting group of chemical pollution scientists publish article highlighting ten aspects for delegates to consider; non-profit academic organization International Panel on Chemical Pollution hosts webinar on conflicts of interest in chemicals and waste governance
What should be included in UN Plastics Treaty negotiations?
International negotiators prepare for first meeting to negotiate the UN treaty to end plastic pollution; scientists, civil society organizations, and governmental bodies publish reports proposing suggestions for what and how to negotiate; many reports support including controls on chemical additives as part of the treaty
Wrestling with the externalities of the plastics supply chain
As the first meeting of the Intergovernmental Negotiation Committee of the UN Global Treaty to End Plastic Pollution approaches, publications highlight the diverse effects the plastics supply chain has on human health and the environment, particularly the burden on vulnerable communities
Maine publishes food contact chemicals of concern list, postpones PFAS ban
US state of Maine Department of Environmental Protection (DEP) publishes food packaging chemicals of high concern list; mandated by state legislation and limited to 10 chemicals; DEP postpones ban on PFAS in food packaging originally meant to begin in 2022; phthalate ban went into effect January 1, 2022
Scientists warn over-production of chemicals altering planetary systems
Peer-reviewed study finds pollution from synthetic chemical production and plastics is now altering planetary systems vital to human survival; recommends implementing cap on chemical production and release similar to greenhouse gases
Study characterizes chemicals present within recycled products
Scientific study characterizes chemicals contained in 210 consumer products made of recycled or virgin material regarding identity, functional use, structural class, and origin and prioritizes chemicals; 65% of chemicals with greater concentrations in recycled materials, along with a higher number of flame retardants, biocides, dyes, and fragrances in recycled materials
Whistleblowers claim EPA is hiding chemical risks
The Intercept reports four career staff members of the US Environmental Protection Agency (EPA) claim that the agency is hiding risks discovered in toxicological assessments of chemicals; plans additional follow-up articles to further investigate the claims
South Korean study investigates chemical exposures from food contact plastics
Scientific study examines chemical migration from seven types of food contact plastics available in South Korea; finds overall migration within national regulatory limits; considers estimated human exposures to terephthalic acid, acetaldehyde, 1,4-butanediol, and lead to be safe
Studies examine phthalate migration from PVC films and adhesives
Recent articles in scientific journals analyze plastic packaging and adhesive materials used in contact with food for phthalate content and migration; polyvinyl chloride (PVC) cling films and adhesive labels are source of phthalate contamination to food; food characteristics, e.g., structure of fruit peel, lipid content, influence migration level; recommend avoiding direct food contact to labels, minimizing exposure time
