Literature review of micro- and nano(bio)plastics research; scrutinizes the complexities of micro- and nano(bio)plastics degradation and their toxicological effects; highlights gaps in long-term impact studies and interactions with environmental conditions; challenges the assumption that “biodegradable” means complete degradation; calls for greater transparency in research practices to bolster collective understanding

Deciphering the differences in plastic particles reported in foods
Two studies investigate micro- and nanoplastics measured in foods; review the range of reported values and diversity of study methods; make suggestions to standardize research methodologies; one study outlines additional standards the micro – nanoplastics research community needs to develop in order to assist regulators

Mapping microplastics in the male reproductive system
Study provides an in-depth look at microplastics in the male reproductive system, analyzes human and mouse samples to chart concentrations and polymer types; finds microplastics in all human testes samples and majority of semen samples; larger plastic particles may get trapped in testis, leading to higher concentrations; identifies correlation between urbanization, home-cooked meals, and body scrub used to microplastics concentration

Studies review human exposures and effects of micro- and nanoplastics
Three studies investigate micro- and nanoplastics – source, organ deposition, and reproductive effects; detect up to 240,000 plastic particles/L in bottled water with 90% being nanoplastics; find microplastics in human lung, intestine, and kidney tissues; polyethylene particles found to affect placental function in mice

Ultra-processed food intake can increase human exposure to phthalates and microplastics
Two studies analyzed ultra-processed foods for phthalates and microplastics; report that consumption of ultra-processed foods and fast food during pregnancy increases exposure to phthalates; link lower socioeconomic status to increased ultra-processed food consumption and phthalate exposure; find highly-processed protein products in the US to contain significantly more microplastics than minimally-processed products; hypothesize plastic processing equipment to be one main source

PFAS research snapshot Q4 2023: presence, migration, health concerns, and regrettable substitution
Scientists detect two per- and polyfluoroalkyl substances (PFAS) in plastic food storage bags; study assesses PFAS in 119 single-use food packaging and tableware samples from around the world and detectes PFAS in 54%; two reviews raise awareness of PFAS impact on human liver health and safety issues connected with the PFAS substitutes – polyfluoroalkyl phosphate esters (PAPs); scientist calls for more research to assess combined environmental effect of microplastics and PFAS

Minderoo Foundation systematically maps human health effects from plastic-associated chemicals
Interactive and openly available, the Plastic Health Map summarizes human health outcomes of certain plastic-associated chemicals and particles as published by peer-review articles between 1960 and 2021; includes more than 3500 studies for 1557 chemicals; identifies gaps, including only 30% of chemicals have been investigated for health impacts, few studies in low-income countries

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

Scientists detect microplastics in amniotic fluid, effects on testicular aging
Two studies investigate microplastic presence or effects in female and male reproductive organs; small cohort study finds low number of microplastics to be present in human amniotic fluid besides the placenta; in vitro and mice in vivo study reports microplastics induce premature testicular aging and identifies underlying pathways

Microplastics can lead to behavioral changes in mice
Scientists find polystyrene microplastics reduce cell viability, translocate in the body, modify mice behavior, and change their liver and brain immune markers after short-term exposure; effects potentially age-dependent; two reviews summarize nano- and microplastic impacts on fertility and potential implications
