Airborne microplastics are emerging pollutants originating from disposable tableware, packaging materials, textiles, and other consumer goods. Microplastics vary in shape size exposed to external factors break down into even smaller fractions. abundant both urban natural environments, including water bodies glaciers, as particles can travel long distances. The potential toxicity of airborne cannot be underestimated. Microparticles, especially those < 10 µm, entering the human body through inhalation or ingestion have been shown cause serious adverse health effects, such chronic inflammation, oxidation stress, physical damage tissues, etc. adsorb toxic chemicals biopolymers, forming a polymer corona on their surface, affecting overall toxicity. In addition, also affect carbon dynamics ecosystems impact biochemical cycles. approaches improve sampling techniques develop standardized methods assess still far being perfect. mechanisms microplastic intracellular tissue transport not clear, is understood well. Reduced consumption followed by collection, reuse, recycling contribute solving problem. Combinations different filtration membrane bioreactors used optimize removal contaminants wastewater. this review we critically summarize existing literature microplastics, distribution, identification, safety assessment.

Dust storms, increasingly prevalent due to anthropogenic climate change, pose a significant environmental hazard by facilitating the long-range transport of contaminants, including ubiquitous microplastics (MPs). These plastic particles, originating from diverse sources such as road dust and landfills, readily adsorb other harmful substances during storm events, potentially amplifying their health impacts. This comprehensive review critically examines multifaceted exposure pathways dust-associated MPs, elucidating crucial role vectors for pollutant dispersal. While preliminary studies on cell lines suggest potential carcinogenic effects, robust evidence linking MP cancer development in humans remains limited. Further research is essential fully comprehend long-term implications these contaminants. Recognizing analytical challenges posed ubiquity complex nature meticulously evaluates current detection techniques various matrices, highlighting both advancements limitations. Fourier-Transform Infrared Spectroscopy (FTIR) emerges preeminent tool its broad applicability operational ease, alternative approaches like Laser Direct Imaging (LDIR), Raman micro-spectrometry, niche thermogravimetric analyzers coupled with mass spectrometers (TGA-MS) hot needle tests demonstrate specific applications. By comprehensively revealing alarming rise MPs intricate complexities detection, this aims stimulate effective mitigation strategies inform further into consequences.

Abstract The microplastics (MPs) formed by broken plastic film may migrate in the soil under drip irrigation. To investigate migration distribution of MPs desert farmland irrigation conditions, our study was conducted on Xinjiang (China). A MP penetration testing device set up combination with methods to conduct a simulation experiment. results showed that amount significantly positively correlated irrigation, and negatively depth; addition, relationship between different types was: clay &lt; sandy loam soil. Under rates were 30.51%, 19.41%, 10.29% soil, clay, respectively. ability these three particle sizes polyethylene ranked as follows: 25 147 μm &gt; 0 250 μm. When volume 2.6 3.2 L, horizontal distances exceeded 5 cm, vertical reached more than 30 cm. Our findings provide reference data for migration. Environ Toxicol Chem 2024;43:1250–1259. © 2024 SETAC
