Smithers conference covers global developments in food contact regulations and materials; speakers on day one review recent and upcoming changes to food packaging regulations in the US, Canada, and the South American trade bloc Mercosur
Two studies associate microplastic exposure with cancer
Review of occupational health studies finds workplace exposure to polyvinyl chloride (PVC) particles likely induces liver carcinogenicity; research study finds polystyrene nanoplastics to speed up ovarian cancer development in mice
US government and stakeholders debate how to improve recycling
US Environmental Protection Agency (EPA) sets target national recycling rate of 50% by 2030; stakeholders identify recycling data gaps as key limitation; call for new national standards and legislation improving reporting, use of recycled content; upcoming changes in government administration create uncertainty
Scientists explore effects of micro- and nanoplastics on mammals, including humans
Research studies show maternal polystyrene (PS) particle exposure can cause testicular and hepatic toxicity in male mouse offspring; report PS microplastics affect rat ovary function; find correlation between human fecal microplastics levels and Inflammatory Bowel Disease; reviews summarize potential human health effects; study develops a tool to screen and prioritize micro-and nanoplastics toxicity studies for human health risks evaluation
Bioassay-based analysis of chemicals in paper & cardboard
Scientific study evaluates presence of hazardous chemicals in methanolic extracts from paper and cardboard food contact materials (FCMs) using several bioassays; finds oxidative stress (52%), genotoxicity (100%), impacts on xenobiotic metabolism (74%), antiandrogenic (52%) and antioestrogenic effects (39%); recommends an effect-based approach for hazard identification of food contact chemicals
Implementation of EDC criteria for biocides
EU biocides authorities settle how criteria to identify endocrine disruptors for biocides will be realized; criteria to apply from June 7, 2018; ECHA and EFSA prepare final guidance document
In vitro testing of paper and board FCMs
Scientists test paper and board FCMs in 8 in vitro bioassays; all 20 samples showed positive responses in at least one of the assays; chemicals in paper and board FCMs require further investigation to ensure safety
Vote on EDC criteria again postponed
EU Commission’s PAFF Committee discusses EDC criteria but refrains from vote; Member States still in disagreement over Commission’s latest proposal; no new meeting scheduled yet
Vote on EDC criteria scheduled
Next meeting of EU Commission and Member States on revised criteria to identify endocrine disrupters to take place on May 17-18, 2017; vote foreseen despite persisting concerns
Studies report on oligomer migration from food packaging
Scientists perform migration experiments for oligomer analysis; one study detects eight chemicals including six non-intentionally added oligomers to migrate from multilayer biodegradable teacups; second study reports on oligomer migration from polycarbonate tableware as ‘hidden source’ of bisphenol A (BPA)
