Atmospheric Microplastics and Nanoplastics: A Systematic Review of Sources, Transport, Chemical Transformation, Pollutant Interactions and Climate Implications
AI summary Read the abstract
Tiny plastic particles from car exhaust, synthetic clothing, and industrial waste don't just pollute land and water—they're floating in the air we breathe, and this review pulls together what scientists currently know about them. These particles can travel long distances, break down into even smaller nanoplastics, and pick up toxic chemicals like heavy metals and "forever chemicals" (PFAS) along the way, potentially making them more harmful when inhaled. While researchers agree this airborne plastic pollution likely affects both our health and the climate, they say better tools are still needed to fully measure the risks, so this remains an area to watch r
Atmospheric MPs and NPs are now acknowledged as pervasive global environmental pollutants whose environmental role in atmospheric chemistry, pollution and climate change is progressively recognised. In this review we provide an integrated overview of current scientific understandings on sources, occurrences, transport, chemical evolution, pollutant interactions and environmental impacts of atmospheric plastic particles. Emissions primarily come from transport sector, industrial processes, man-made fibres and waste management system, whereas secondary emissions may come from fragmentation and re-suspension of plastic debris from land and sea surfaces. Once in the atmosphere, MPs and NPs can undergo long-range transport and both wet and dry deposition to pollute the remote ecosystems. Ultraviolet irradiation, ozone, hydroxyl radical and heterogeneous reactions in atmosphere can result in the weathering of plastic particles. The changes in particle morphology, surface functionalization and transformation from MP to NP have a profound effect on interaction of plastic with POPs, heavy metals, PAHs and PFASs to function as a reactive pollutant carriers. Increasing evidence is revealed on the role of atmospheric plastic on radiative forcing, cloud microphysics, formation of SOA and human health by inhalation. Although, the study on atmospheric MPs/NPs has gained significant interest and rapid progresses, a substantial research gap still existed for detection of nanoplastic, source apportionment and their atmospheric transport modelling and climatic feedback, therefore future study will need the development of standardized methodology, analytical technology and incorporating atmospheric plastic particles in environmental monitoring programs.

Physico-Chemical Characteristics, Instrumental Analyses, and Transportation of Airborne Microplastics
AI summary Read the abstract
This review paper pulls together what scientists currently know about tiny plastic particles floating in the air we breathe, both indoors and outdoors. These particles come from sources like clothing fibers, tire wear, and ocean spray, but researchers still don't fully understand how much we're exposed to or what it means for our health. The takeaway: airborne microplastics are everywhere, and more research is needed to know the real risks.
Atmospheric Microplastics: Perspectives on Origin, Abundances, Ecological and Health Risks
AI summary Read the abstract
This review summarizes current knowledge about microplastics in the atmosphere, including their sources, how far they travel, and potential health effects from inhalation. Researchers found that airborne microplastics can carry toxic chemicals deep into the respiratory system and may contribute to respiratory problems and other health concerns. The study emphasizes that atmospheric microplastic pollution remains poorly understood due to a lack of standardized measurement methods.
Atmospheric Microplastics: Research Progress, Hotspots and Prospects of Global Environmental Problems
AI summary Read the abstract
Tiny plastic particles are floating in the air all around us, indoors, outdoors, even in remote places, and we're likely breathing them in every day. This review of over 280 studies finds that while scientists know these particles can travel long distances and get into our lungs, research methods vary so much that we still can't say exactly how much is truly harmful to human health. The takeaway: airborne microplastics are a real and growing concern worth watching, but more consistent research is needed before we know the actual health risks.
