Studies assess PFAS, OPEs, and plasticizers in paper & board

Review summarizes per- and polyfluoroalkyl substances (PFAS) migration from paper food packaging into food and food simulants and identifies dietary exposure of PFAS as potential human health risk; study highlights need to further evaluate organophosphate esters (OPEs) and prohibited PFAS in paper and aluminum foil food packaging; scientists analyze and recommend extraction method to assess plasticizers in recycled paperboard

Plastic recycling: company commitments and chemical safety challenges

Scientists report most large companies commit to reducing plastic pollution but focus on recycling; extrusion of recycled materials and legacy compounds in recycled materials as safety challenge; some substances increase others decrease with the increase in recycled content in polyethylene terephthalate (PET) bottles; tentatively identify 212 volatile chemicals in 57 different recycled PET flakes available in China; present migration model to characterize the exposure and risk of PET oligomers

Ways forward to improve polymer assessment and management

Critical review evaluates regulatory approaches of polymer assessment and management; identifies critical knowledge gaps by comparison with recent scientific findings; proposes policy options for safe and sustainable polymer use; suggest more transparency, standardized testing procedures, and improved understanding of environmental fate and hazards

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

Study investigates quantity and risk of oligomers in PBT

Researchers analyze oligomer in extracts and migrates of polybutylene terephthalate (PBT) food contact articles also comparing levels in food and food simulants; report human exposure to oligomers can exceed daily threshold in some scenarios; express the need for toxicological evaluation of PBT oligomers

WHO report on potential human health implications of microplastics

World Health Organization (WHO) report assesses human exposure to micro- and nanoplastics via inhalation and diet as well as potential health implications; finds available data of limited use for risk assessment

Non-standard studies contribute to over half of REACH restrictions

Scientists assess studies used to restrict chemicals under REACH; report data from non-standard studies contribute to the majority of REACH restrictions; 30% of studies the European Chemicals Agency identifies as key to a restriction are not included in REACH registration database; recommend increasing transparency

Switzerland: 25% of PVC lid gaskets exceed plasticizer migration limits

Swiss national campaign analyses 109 oily food samples packaged in glass jars on the compliance of migration of plasticizers from their lid gaskets; comparison with European campaigns conducted a decade ago shows similar proportion of non-compliant samples with non-polyvinyl chloride (PVC)-gasket; urges food businesses to pay more attention to the suitability of their products lids

Viewpoint: Subthreshold effects need consideration in chemical risk assessment

Scientists point out chemical risk assessments worldwide neglect current scientific knowledge; advocate to consider potential subthreshold effects in regulatory risk assessment

Scientists identify food packaging as organophosphate ester source

Scientists establish organophosphate esters (OPEs) baseline concentration in foodstuff across China and investigate the contamination sources; report extensive contamination of Chinese foodstuff with OPEs; uncover food packaging as source of these OPEs
