Smithers conference covers global developments in food contact regulations and materials; speakers on day two review recent and upcoming changes to food packaging regulations in China, Japan, India, and Southeast Asia
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
11th meeting of the Conference of the Parties to the Stockholm Convention lists UV absorber as Persistent Organic Pollutant (POP); first non-halogenated POP under the Convention; also listing of flame retardant dechlorane plus and pesticide methoxychlor in Annex A
Emerging evidence and systematic analyses highlight adverse effects of bisphenols and phthalates on cardiovascular health; meta-analysis of US National Health and Nutrition Examination Survey data from 2003-2016 finds significant association of cardiovascular disease with bisphenol A; prenatal exposure particularly detrimental; calls for more mechanistic research, evaluation of cardiovascular safety profiles for substitution chemicals
Review summarizes plastic-associated bisphenol A (BPA) sources, exposure, and human health risks; dietary bisphenol exposure via packaged food consumption in Saudi Arabia is potential human health concern; review discusses bisphenols’ effects on the cardiovascular system and recommends human-relevant studies with bisphenols other than BPA; consensus scoring analysis identifies endocrine-disrupting food contact chemicals potentially interacting with nuclear receptors
Scientists develop collisions cross section (CCS) database for leachable and extractable food contact chemicals (FCCs) to help in chemical identification during targeted and untargeted analysis; database covers 1038 CCS values; study tentatively identifies >100 migrants from 24 plastic food packaging articles including 11 that are of potential concern or are priority hazardous substances
Kenya, Ghana, Cote d’Ivoire, Nigeria, and Rwanda implementing Globally Harmonized System of Classification and Labeling of Chemicals (GHS) in national policy; Sierra Leone and Malawi partner with the UN Environment Program (UNEP) to study chemical and waste management within the countries to design long term policies and projects
Recent studies perform semi-systematic review of published circular economy literature focusing on plastics over past 21 years, develop framework for plastics in circular economy; find Dutch food packaging plastic waste polluting oceans, question effectiveness of recycling; summarize chemical and microbial hazards related to circular food production systems
European Commission’s Working Group concludes that bamboo-based additives are not authorized per se for use in plastic food contact materials in the EU; business operators to explicitly demonstrate safety by migration testing; migration of melamine, formaldehyde of high concern; additional concerns about misleading labeling and advertising
Scientists summarize literature on chemicals in can-packaged food including metals, plastic-associated chemicals, and furans; report generally low contaminant levels but a lack of non-targeted and suspect screenings; find canning steps, internal and external factors to influence contaminant levels
