Recent studies explore uptake pathways of microplastics; uptake has increased in recent years; rapidly industrializing Southeast Asian countries more impacted; food packaging responsible for approx. 2.98 × 103 microplastics/person/year; higher exposure for regular consumers of bottled water, tea brewed from plastic tea bags, or ultrafiltered milk

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

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
Topics: microplastics, nanoplastics

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

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
