Two in vitro studies analyze plastic particle effects using human cells; find polystyrene (PS) particles change metabolism of human colon cells similar to a carcinogen; PS nanoplastics may have cytotoxic and genotoxic potential on human blood lymphocytes; mouse study indicates microplastics increase risk of insulin resistance; researchers calculate particle ingestion from takeaway containers
BPS and other color developers migrate from food labels into food
Scientists analyze 140 Canadian samples of food packaging and thermal labels; first to demonstrate that bisphenol S (BPS) and alternative chemicals found in food labels migrate through packaging materials into food; study assesses levels of BPS and other bisphenols in 79 canned Turkish foods; detect BPS in six samples in levels up to 0.036 mg/kg food
Studies investigate extractable and leachable FCCs, present collision cross section database
Scientists develop collisions cross section (CCS) database for leachable and extractable food contact chemicals (FCCs) to help in chemical identification during targeted and untargeted analysis; database covers 1038 CCS values; study tentatively identifies >100 migrants from 24 plastic food packaging articles including 11 that are of potential concern or are priority hazardous substances
Commentary on microplastics as a vector for chemical transport
Scientists respond to perspective article providing clarifications on plastic-driven long-range environmental transport (LRET) of chemical additives; discuss nine shortcomings of the perspective; suggest omitting the perspective article in discussions on plastic debris-associated LRET of additives
VZBV finds consumers are confused about food contact materials
Market research from German consumer organization Verbraucherzentrale Bundesverband (VZBV) finds consumers are concerned about food packaging safety but have little understanding of chemicals in packaging; consumers assume all food contact materials and their components have been tested for safety
European Parliamentarians host events on food packaging safety
EU Green Week 2023 includes panels discussing food packaging safety and plastics in a circular economy
Study detects DNA-reactive, mutagenic substances in recycled PE, PP, and PS
119 plastic samples including polyethylene (PE), polypropylene (PP), polystyrene (PS), and polyethylene terephthalate (PET) tested for mutagenicity; no DNA-reactive, mutagenic substances in PET but in 51 of the other samples, making them unsafe, especially for food contact applications; recycling process identified as source; dataset of over 600 organic chemicals in recycled high-density PE pellets published
Reviews examine biobased polymers
Several recent reviews examine the value chain of biobased polymers; discuss clarification of terms such as biobased, degradable, biodegradable, and compostable; define “biotechnological recycling (bio-recycling)” as the use of enzymes and microorganisms in a technological setting to biodegrade polymers; three biodegradable polymers assessed in marine field trials
FPF Workshop 2020: Scientific research and policy making
Six speakers share their views on how to improve food contact material (FCM) safety; different approaches might complement one another; linking scientific research, policy making and industry initiatives could be the key to safe FCMs
Scientists use in silico-based models to prioritize food contact chemicals
Two studies applied computational methods to screen food contact chemicals (FCCs) for carcinogenic properties or interaction with 31 nuclear receptors; one identifies 44 potential carcinogens among 1623 assessed FCCs; other finds more than half of 8091 screened FCCs with high binding affinity for several nuclear receptors
