“…6 The atmospheric aerosol collected was considered as HIA. For the sake of consistency with previous studies, 10,35 the whole sampling period lasted 2 h, composed of four sections with 30 min sampling intervals to match the following HEB sampling (e.g., 9:30 a.m. to 10:00 a.m., 10:30 a.m. to 11:00 a.m., 11:30 a.m. to 12:00 p.m., and 12:30 p.m. to 13:00 p.m.). To assess the sampling efficiency of the homemade atmospheric aerosol sampling device, indoor aerosol particles were also collected on PFTE filters (Whatman GF/F, 0.22 μm pore size, 45 mm diameter) by active pump sampling.…”

Human exposure to microplastics (MPs), especially from indoor air, has aroused growing public concern, but very little is known about the assessment of individual MPs inhalation exposure. In this study, a total of 30 volunteers were recruited from Shanghai, China. Both human inhaled indoor aerosol (HIA) and human exhaled breath (HEB) samples were pairwise collected for each participant and analyzed through micro-Raman imaging spectroscopy. MPs were detected in all samples, averaging 43 ± 16 (range of 11–92) items/m3 for HIA and 12 ± 5 (range of 3–28) items/m3 for HEB. Moreover, the dominant components in all samples were small fragment- and fiber-shaped MPs. It is estimated that the daily intake of HIA was roughly 704 ± 254 MPs items, most of which would deposited in the airway with 526 ± 203 MPs items, whereas 178 ± 75 MPs items could be daily discharged via HEB. The actual daily inhalation exposure of MPs could be overestimated by 1.33 times with the HIA-based approach and by 1.40 times for smaller MPs (<10 μm). These results suggest that integration of HIA and HEB should be considered when evaluating individual MPs exposure via respiration.

“…13 This study defined the concentration of MP in three indoor environments, namely, houses, public transport, and working places, which are representative of urban life. 14 The highest mean MP concentrations were found on buses (17.3 ± 2.4 MP/m 3 ), followed by subways (5.8 ± 1.9 MP/m 3 ), residences (4.8 ± 1.6 MP/m 3 ), and workplaces (4.2 ± 1.6 MP/ m 3 ). Polyamide, PA (51%), polyester PES (48%), and PP (1%) were the polymers identified and also being the most common ones in personal care products and synthetic textiles.…”

“…Polyamide, PA (51%), polyester PES (48%), and PP (1%) were the polymers identified and also being the most common ones in personal care products and synthetic textiles. 14 In another study, indoor dust samples from residential areas (apartments) had the highest abundance of MPs, followed by offices (896 MPs/g; n = 50), business hotels (843 MPs/g; n = 53), university dormitories (775 MPs/g; n = 48), and university classrooms (209 MPs/g; n = 44). 15 Soltani et al assessed the presence of MPs in Australian homes, which demonstrated that children under 6 months of age faced the highest exposure risk.…”

Objective: To assess the impact of microplastics (MPs) on human health. Data Source: The authors conducted a non-systematic review of articles published in English, Portuguese, French, and Spanish in the last decade in the following databases: PubMed, Google Scholar, EMBASE, and SciELO. The keywords used were: microplastics OR nanoplastics OR marine litter OR toxicology OR additives AND human health OR children OR adults. Data summary: MPs are a group of emerging contaminants that have attracted scientific interest and societal attention in the last decade due to their ubiquitous detection in all environments. Humans can primarily be exposed to MPs and nanoplastics via oral and inhalation routes, but dermal contact cannot be overlooked, especially in young children. The possible toxic effects of plastic particles are due to their potential toxicity, often combined with that of leachable additives and adsorbed contaminants. Conclusions: Unless the plastic value chain is transformed over the next two decades, the risks to species, marine ecosystems, climate, health, economy, and communities will be unmanageable. However, along with these risks are the unique opportunities to help transition to a more sustainable world.

“…It is also hypothesized that MPs can cause damage to the tissues of the human respiratory system depending on individual host responses and the nature of the particles [ 14 ]. MPs may accumulate in tissues and potentially induce local cytotoxicity, enhancing hosts’ immune responses and tumorigenesis [ [15] , [16] , [17] ]. Such notions require further clinical data-based proof.…”
