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
AURORA partners discuss research progress going into fourth year
Project partners reunite in Prague for third in-person meeting; work packages share updates on research progress and current challenges; celebrate milestones in passing the project’s half-way mark; outline research efforts for coming year
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
Review summarizes current picture of ‘human-centric’ micro- and nanoplastics research
Scientists review and briefly summarize available scientific literature on each step of microplastic exposure from source to effect in humans; includes sections on sources of microplastics, exposure routes, levels, deposition in the body, and confirmed health effects; highlight current shortcomings
AURORA study on household plastics exposure launched
AURORA partners from the University Medical Center Utrecht have launched a study investigating micro- and nanoplastics in females of reproductive age; includes 100 participants from around Utrecht, the Netherlands; first study visits started in July 2023 and will conclude in February 2024
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 marker after short-term exposure; effects potentially age-dependent; two reviews summarize nano- and microplastic impacts on fertility and potential implications
Plastics stay longer in the ocean than previously estimated, scientists report
3D-model study finds 3200 kilotonnes of buoyant marine plastic litter in 2020, majority on the surface and >25 mm in size; projects annual growth of 4%; solves mystery on ‘missing’ sink for plastic pollution
