Publications from government, academia, civil society organizations, and consultancies paint problematic picture of a circular plastics economy; plastic packaging waste per person found to increase over last decade; low percentage of plastic produced is effectively recycled; pyrolysis (a type of chemical recycling) of plastics produces 9x more emissions than mechanical recycling; “biodegradable” and “compostable” plastics found to not break down in home compost systems
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
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
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
Phthalates: impact on leiomyoma growth and mixture risk
Study identifies mono(2-ethyl-5-hydroxyhexyl) phthalate (MEHHP) exposure as high-risk factor for leiomyoma growth on epidemiological and mechanistic level; European biomonitoring of five reprotoxic phthalates demonstrates necessity to integrate mixture risk assessment into regulatory practice; targeted analysis shows migration of five phthalates from polypropylene food packaging
