Abstract Aim Airborne microplastics (AMPs) present significant health risks indoors due to prolonged exposure. This study evaluates AMP concentration, types, and impacts in residential, office, commercial settings Ahvaz, Iran, during winter summer. The annual inhaled dose was calculated based on typical occupancy patterns. Methods particles were collected from 30 locations using active sampling at 5 L/min for 8 hours. Raman spectroscopy identified polymers, SEM-EDX analysis examined surface morphology elemental composition. estimated MP concentrations indoor exposure times. Results highest offices (up 48 MPs/m³), moderate residential areas, lowest settings. Predominant AMPs spherules (67.2% winter, 69.3% summer), with black/gray being most common. Smaller (< 250 µm) more frequent 2,952 MPs/kg/year, mainly followed by spaces. Conclusions underscore the need policies reduce pollution, improve ventilation, manage risks, especially high-occupancy areas like offices. Future research should focus advanced chemical analyses size-specific assessments better evaluate microplastics.

Airborne micro and nanoplastics (MPs/NPs) are a growing issue due to their possible health hazards. Since the current bibliography lacks thorough evaluation, this review examines sources, environmental dynamics, impacts of airborne MPs/NPs. Through atmospheric transport processes, these neo-pollutants spread around world after being released, potentially settling in urban remote areas. This is first compare active passive aerosol sampling methods, microscopy, thermochemical, spectroscopy analytical techniques, with focus on limitations precisely quantifying micro-nanoscale plastic particles. It also draws attention potential toxicological effects inhaled MPs/NPs, which can lead oxidative stress, respiratory inflammation, other negative consequences. concludes by examining how MPs/NPs may worsen ecological impact serving as carriers hazardous chemicals microbial pollutants. Despite awareness, there still many unanswered questions, especially about long-term exposure conditions affect The aim was bring MP/NP promote development advanced monitoring systems, new multidisciplinary scientific field for study novel pollutants, global regulatory frameworks.

Abstract Background Nanoplastics (NPs) are released into the environment through degradation of plastic objects, leading to human exposure. Due their small size, concerns have been raised about potential hazards respiratory tract, as ultrafine and nanoparticles known penetrate till alveolar regions lungs, potentially impairing functions. Thus, in present study, we used model polystyrene doped with fluorescent metal europium (PS-Eu) enhance understanding NPs hazard investigate adverse outcomes associated exposure lungs using (A549) bronchial (Calu-3) cell models grown 2D 3D submerged conditions or quasi air-liquid interface (ALI) (3D). Results Briefly, after in-dept physicochemical characterization particles, assessed impact on ROS production, viability (AlamarBlue lactate dehydrogenase assays) barrier integrity (lucifer yellow assay TEER measurement), finding no negative effects either model. However, cells, particles increased acidic organelle activity. Transmission electron microscopy Raman showed, both models, a dose- cell-dependent particle uptake PS-Eu accumulating numerous large endo-lysosomes, which, transwells-grown A549 often contained also lamellar bodies (LBs), organelles involved surfactants storage secretion. After extensively quantifying surfactant proteins (SP) pellet supernatant fractions treated observed significant reduction several members this family, including protein B, which is crucial for body formation surface tension regulation lungs. In quasi-ALI Calu-3 cultures instead, significantly upregulated interleukin 6 (IL-6) transforming growth factor beta β (TGF-β), zonula occludens 1 (ZO-1), mucin (MUC) 5B mRNA expressions causing moderate proinflammatory response. Conclusion Our results show that does not induce acute cytotoxicity these but affects cell-specific functions like surfactant, mucin, cytokine production. This underscores limitations relying solely standard tests assessment highlights importance investigating function-specific signaling pathways. To support researchers assessment, propose specific classes biomarkers test vitro lung models.
