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
Scientists propose and apply NIAS identification approaches
Review provides guidance to select analytical technique for non-intentionally added substances (NIAS) identification and quantification in food contact materials (FCMs); scientific studies analyze NIAS migrating from FCMs; develop model to predict collision cross-section values to identify NIAS in FCMs; detect polyethylene terephthalate (PET) oligomers in post-mortem blood samples
FPF Workshop 2020: Values and transparency in science
Kevin Elliott discusses how values can influence scientific judgements or be themselves affected by them; transparency plays an important role in responding to challenges caused by value-laden judgements; contents and venues chosen for transparent communication need to be adjusted according to each stakeholder’s needs
What should be included in UN Plastics Treaty negotiations?
International negotiators prepare for first meeting to negotiate the UN treaty to end plastic pollution; scientists, civil society organizations, and governmental bodies publish reports proposing suggestions for what and how to negotiate; many reports support including controls on chemical additives as part of the treaty
Researchers detect microplastics in human semen and heart
Four recent studies assess microplastics: in human semen, heart, from baby food containers, and suitability of in vitro models to investigate human health effects; find microplastics in six out of ten semen samples, find impacts on semen quality; samples from cardiac surgery patients contain microplastics in heart and surrounding tissue; billions of nano- and microplastics released from plastic baby food containers; outline challenges and recommendation of studying plastic particles in vitro
Science and statecraft at the second Plastics Treaty negotiation
Diplomats from across the globe descended on Paris, France to continue developing the UN treaty on plastics pollution; Scientist’s Coalition for an Effective Plastics Treaty members spoke to delegates from every continent, representing 33% of the world’s population; UN secretariat will develop INC-2 synthesis report, create zero draft by INC-3; elements for intersessional work can be submitted until August 15, 2023; INC-3 in Nairobi, Kenya in November 2023
A novel concept for improved safety assessment of FCMs guided by public health concerns
Over 20 scientists present a vision for safer food contact materials (FCMs); propose new approach to test all chemicals that migrate from final product for their contribution to highly prevalent chronic diseases
Review on EDCs and breast cancer calls for research inclusivity
Researchers review association between endocrine-disrupting chemical (EDC) exposure, specifically per- and polyfluoroalkyl substances (PFAS) and parabens, and breast cancer development; report structural racism increases EDC exposure of marginalized communities; emphasize need for considering socially disadvantaged populations in research to mitigate exposure and improve breast cancer disparities; review finds bisphenol A (BPA) replacements BPS and BPF as carcinogenic as BPA
Ongoing efforts to prevent plastic pollution
Pacific island Vanuatu to ban single-use plastic bags and bottles to prevent ocean pollution; Press of Atlantic City calls on visitors and residents of New Jersey shoreline to reduce use of plastic convenience items
BPA linked to increased blood pressure
Study links consumption of canned beverages with BPA lining and acute blood pressure increase
