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
New study finds BPA active in aggressive breast cancer cell line, blocks common breast cancer drugs
Review summarizes microplastics abundance and characteristics in human biological samples including current research approaches employed, challenges, and prospects; study indicates microplastics impact human meconium and placenta microbiota; review outlines current evidence on microplastic effects upon exposure during early developmental stage
Karim Bschir from ETH Zurich argues that ‘good science is not value-free’ because scientists routinely make value-based judgments; he proposes that scientists should make their values explicit
Scientists study migration from food packaging films made of polypropylene; 74 compounds identified, 76% of them NIAS; 35% of samples show migration exceeding either SML or Cramer class-based recommendations
Researchers from several European and Chinese institutions develop methods to explore chemicals in food contact materials (FCMs); report styrene migration from different polystyrene FCMs into several food matrices; detect photoinitiators in paper FCMs and chlorinated paraffins in green tea and its packaging; find irradiation treatment of metalized polypropylene to reduce migration of tested chemicals
Scientists perform target and non-target screening of recycled plastics and provide recommendations on methods; detect >280 organic chemicals and metals in 21 plastic flakes and pellets used in recycling; analyze several recycled polymers and find polyethylene terephthalate (PET) the only one currently complying with European circular economy requirements; compare analytical methods to assess the chemical composition of recyclates giving their strenghts and limitations
Updated report on legal battle involving Tritan® plastic marketed as “EA-free”
Scientists investigate in vitro toxicity of extracts from bioplastics and plant-based food contact articles; find strongest toxicity induced by cellulose- and starch-based products; emphasize similar toxicity profiles among bio-based, biodegradable, and conventional plastics
Researchers develop high-resolution spectral database and method for the identification of 56 selected organic plastic additives; indicates presence of multiple additives when applied to polypropylene and polylactic acid food packaging; highlight chemical signature not polymer but product dependent and “bioplastic” just as conventional plastics contain harmful additives
