Peer-reviewed article summarizes occurrence, source, and characterization of microplastics in food and beverages; reports highly variable concentrations within and between food categories; identifies water bodies, packaging, and food handling as source of microplastic contamination
University of Queensland opens one of the world’s first plastics contamination-controlled labs jointly with Minderoo Foundation; studies micro- and nanoplastics in human blood and tissue samples; steel walls, cotton lab coats, and extensive testing of all construction materials limits environmental plastic contamination
European Commission regulation restricts use of perfluorooctanoic acid (PFOA), its salts and PFOA-related compounds as a persistent organic pollutants; sets maximum concentration of 0.025 mg/kg for PFOA and salts, 1 mg/kg for related compounds; series of exemptions also in place
Review summarizes chemicals present in and migrating from food contact articles made with wood, bamboo, and other plant-based materials; researchers identify and quantify 25 non-volatile compounds from bamboo, palm leaf, wood and wheat pulp dishes; tentatively identify 115 non-volatile chemicals in extracts from six plant fiber/plastic composites; detect phthalates in Brazilian dry foods in cellulose-based packaging
Article evaluates pros, cons, and improvement potential of biobased polymers looking at production, end-of-life, environmental, and toxicological impacts; regards bioplastics as promising alternative but not without issues; emphasizes importance of considering economic, social, environmental, and legislative issues when scaling up biobased plastics
Researchers publish study identifying non-monotonic effects on mammary gland development across all ages of rats; finds causal relationship between BPA exposure and effects observed, results counter earlier statements that effects are rather due to random events
Article questions effectiveness of current chemical risk assessment in protecting public health; explains non-monotonic dose response and why it should be considered in assessing chemicals’ toxicity
Scientists detect two per- and polyfluoroalkyl substances (PFAS) in plastic food storage bags; study assesses PFAS in 119 single-use food packaging and tableware samples from around the world and detectes PFAS in 54%; two reviews raise awareness of PFAS impact on human liver health and safety issues connected with the PFAS substitutes – polyfluoroalkyl phosphate esters (PAPs); scientist calls for more research to assess combined environmental effect of microplastics and PFAS
Study determines toxicity and composition of 42 silicon rubber food contact articles; finds 84% of silicon kitchenware to induce endocrine activity; review gives update on the known endocrine disruptors phthalates and bisphenols with focus on detection methods and addressing regulatory concerns; study develops and applies method for phthalate determination in vegetable oils
Justice Angela Furlanetto deemed the Canadian Environment and Climate Change Department’s classification of manufactured plastics products as toxic unconstitutional; the federal government is appealing the decision; single use plastics ban is still in effect
