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.

Nanoplastics (NPs) represent an escalating hazard to both humans and the ecosystem due their pervasive presence. This review delves into (i) widespread occurrence of NPs across different environmental matrices, including food; (ii) routes estimates for human exposure; (iii) mechanisms blood–brain barrier (BBB) crossing; (iv) implications health, with a specific focus on molecular features associated neurotoxicity neurodegenerative processes. The impact central nervous system, ability cross BBB underpinning mechanisms, potential initiate by fostering β-amyloid aggregation, interactions metallo-enzymes (such as superoxide dismutase) are elucidated. analysis transcriptomics epigenomic results, microRNA dysregulation, unveil how could contribute neurological disorders. need considering overlaps among diverse pathogenetic when probing effects is discussed. Additional urgent needs development reliable in vitro models studies able mimic complexity system exposure such more environmentally relevant NPs. Finally, extremely sensitive detection methodologies quantify biological matrices pressing priority.

Micro- and nanoplastic particles have been detected in most environmental compartments. The presence of microplastics the remote marine atmosphere close to large lakes suggests bubble mediated water-air transfer as a source airborne microplastics, however, quantitative estimates plastic emission from surface waters remain uncertain. In this work, we elucidate submicron polystyrene nanospheres by bursting laboratory setting low salinity (salinity 0-1.0 g kg-1), particle diameter (103, 147 269 nm), aqueous number concentrations range 4 × 107-2 109 cm-3, formation rate (0.88-3.35 L min-1 air). Production aerosols was demonstrated using scanning mobility sizer confirmed analysis filter samples pyrolysis gas chromatography coupled mass spectrometry. We show that production aerosol scales linearly with concentration water. Our results suggest small amounts (0.01 kg-1) salt increase production. To best our knowledge is first study 100 nm.

Nano-plastics have been found in snow and evidence shows that they can act as nuclei. The aerosol water-uptake ability is an important property will determine wet deposition, a potential main route for nano-plastics to fall the ground. In this work, we measure hygroscopicity of three nano-plastics: low-density polyethylene (LDPE), terephthalate (PET) polyvinyl chloride (PVC), fourth compound, cellulose, with in-situ techniques via cloud condensation nuclei counter. Cellulose high-molecular weight compound component commonly used paper products. Ultrafine nano-plastic particles range 20 200 nm are explored. Nano-plastic materials LDPE, PET, PVC form droplets more readily than cellulose nanoparticles. high indicates either oligomers or polymer properties water adsorption. Furthermore, single parameter hygroscopicity, κ, derived from different droplet activation models (Flory Huggins Köhler Frenkel-Halsey-Hill adsorption theory) reported. Moreover, molecular weights leached predicted by Flory theory assuming ideal mixing. observed intrinsic size-dependent, hence adsorption-based model could be applied. incorporated into clouds, transported globally, may also removed atmosphere deposition processes. analysis help estimating lifetime transport atmosphere.
