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
NIAS migration from plastic wine corks
Scientific study uses non-targeted chemical analysis to provide an overview of chemicals migrating from 8 wine corks made of ethylene-vinyl acetate; identifies 50 compounds, 84% non-intentionally added substances (NIAS); finds one cork not suitable as food contact material
BPA: predictor of prostate cancer?
New study detects high urinary BPA in prostate cancer patients, cellular changes in prostate cells at low levels of exposure
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
Reverse causation bias in PFOA studies
Scientists suggest increased perfluorooctanoic acid (PFOA) blood levels are consequence of early menopause and kidney disease, not cause
Two articles review oligomers and other chemicals migrating from bio-based products
Research study compares different techniques for oligomer detection and finds polyester oligomers migrate from biopolymers; book chapter discusses catalysts, volatile organic compounds, and additives in bio-based products, including their migration and safety
New method for analysis of BPA in recycled food contact paper
Spanish study shows new and fast method allows for an accurate determination of bisphenol-type compounds and measured BPA in all analyzed recycled materials.
Studies assess composition and safety of chemicals in recycled HDPE
Scientists analyze volatile compounds in recycled high-density polyethylene (HDPE); detect 53 chemicals in two post-consumer HDPE milk bottles including plastic additives and non-intentionally added substances (NIAS); risk assessment shows samples do not comply with plastic food packaging regulation; report re-granulation process in mechanical recycling to remove most but not all odor and volatile organic compounds
Australian government to start regulating packaging
Australian environment ministers agree to “address the use of harmful chemicals in food packaging,” create packaging design standards and targets, harmonize curbside recycling programs; details forthcoming
EFSA: Updated risk assessment of five phthalates
European Food Safety Authority publishes updated risk assessment for the phthalates DBP, BBP, DEHP, DINP, DIDP; retains developed group and individual tolerable daily intake limits; finds no current public health concern but cautions that values set are temporary due to uncertainties
