Little research exists on the magnitude, variability, and uncertainty of human exposure to airborne micro- nanoplastics (AMNPs), despite their critical role in MNPs. We probabilistically estimate global intake AMNPs through three main pathways: indoor inhalation, outdoor ingestion during meals, for both children adults. The median inhalation AMPs is 1,207.7 (90% CI, 42.5–8.48 × 104) 1,354.7 47.4–9.55 N/capita/day adults, respectively. annual 13.18 mg/capita/a 19.10 which approximately one-fifth one-third mass a standard stamp, assuming consistent daily medians. majority AMP number occurs while deposited meals contributes most terms mass.

Abstract Microplastics (MPs) have become a growing concern in the context of environmental pollution, with an increasing focus on their presence indoor environments, including university facilities. This study investigates and characteristics MPs different environments. Initial examination ambient involved physical characterization through optical microscopy, focusing classifying by shape color. Various types MPs, fibers, fragments, pellets, foams, films, lines, were identified, most common colors being black, red, blue, brown. Fragments predominant type found, although accurately quantifying numbers proved challenging due to dense sample content. These displayed rough irregular margins suggestive abrasion. Subsequent chemical elemental was conducted using micro-Raman SEM-EDX, revealing 25 PA 66, PTFE, PP, HDPE, PE. The indicates that inhabitants are exposed airborne (≥ 2.5–336.89 μm) at inhalation rates 13.88–18.51 MPs/m 3 180–240 daily. exhibited significant variations size, distribution varied among environments studied. SEM-EDX analysis revealed elements identified C, O, F, Na, Cl, Al, Si, others consistently detected. research is first comprehensively analyze nine active sampling. Identifying reducing MP contamination these facilities might stimulate more awareness, promote extensive scientific investigation, facilitate development informed policies.

The increase of micro- and nano-plastics (MNPs) in aquatic environments has become a significant concern due to their potential toxicological effects on ecosystems, food web dynamics, human health. These plastic particles emerge from range sources, such as the breakdown larger waste, consumer products, industrial outputs. This review provides detailed report transmission dangers MNPs environmental behavior, interactions within webs, emphasizing toxic impact marine life. It explores relationship between particle size toxicity, distribution different tissues, process trophic transfer through web. MNPs, once consumed, can be found various organs, including digestive system, gills, liver. Their consumption by lower level organisms facilitates progression up chain, potentially leading bioaccumulation biomagnification, thereby posing substantial risks health, reproduction, behavior species. work also how persistence bioaccumulation, pose biodiversity disrupt relationships. addresses implications for particularly contaminated seafood, highlighting direct indirect pathways which humans are exposed these pollutants. Furthermore, highlights recommendations future research directions, integration ecological, toxicological, health studies inform risk assessments develop mitigation strategies address global challenge pollution environments.
