Measuring plastic particles released from food packaging and in human lungs
Scientists investigate plastic particles released from store-bought food packaging as well as human and mice health impacts of exposure; report single-use plastic products release >1012 nano-sized particles during use; find microplastics to suppress lysosomal activity in mouse macrophages; first detection of microplastics within human lung tissue samples; in vitro neurotoxicity study finds microplastics negatively impact human forebrain organoid development

Scientists emphasize importance for LCAs to consider plastic particle impacts
Review provides understanding of how knowledge gaps on long-term plastic particle fate affect life-cycle assessments (LCAs) and distort policy decisions; exemplifies discussion comparing a fossil-based with a biodegradable plastic; highlights importance of covering plastic particle impacts and its unknowns transparently in LCAs to allow reliable material comparisons and responsible decision making

Researchers associate diet and microplastics with EDC exposure
Epidemiological studies investigate association between diet and endocrine-disrupting chemical (EDC) exposure; find recommended healthy diets not protective against EDC exposure; report association of plastic-free diet with reduced urinary bisphenol A (BPA) in children; researchers performing bioaccessibility tests using gut fluids find release of phthalates and BPA from microplastics may pose human health risk

EC launches public consultation on microplastic pollution
European Commission (EC) initiative aims to reduce the release of microplastics into the environment; specifically focuses on expanding research on risks from microplastics contamination in food and water and reducing risks to humans from environmental contamination; consultation open until May 17, 2022

Microplastics: linkage to the gut’s microbiome and autism spectrum disorder
Scientific study reports that gut passages change polyethylene terephthalate (PET) microplastics morphology and alter human microbial colonic community composition; another study finds polyethylene (PE) microplastics to accumulate in the brain and induce autism spectrum disorder-like symptoms using a mouse model
