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

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

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

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

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

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

Study using perfused human placental tissue demonstrates polystyrene nanoplastics affect expression of inflammation and iron homeostasis-related genes; review summarizes that small plastic particles can enter reproductive organs and affect reproductive health, however further research needed to verify the results and assess mechanisms of reproductive toxicity
