A comprehensive review of microplastics in India as emerging air pollutants with implications for current trends and future perspectives
AI summary Read the abstract
This review pulls together existing research on India's air pollution problem, finding that tiny plastic particles from clothing fibers, traffic, road dust, and industrial activity are floating in the air people breathe—with estimates suggesting city dwellers may inhale over 300 to 800 of these particles daily. Early lab studies suggest these inhaled plastics could irritate lungs, cause inflammation, and damage the protective lining of airways, though scientists still need better tools to measure exposure and confirm long-term health risks. The takeaway: airborne microplastics deserve the same monitoring attention as other air pollutants, especially in
Airborne microplastics (AMPs) are increasingly recognized as an emerging component of atmospheric particulate pollution. They are considered to have potential impacts on environmental redistribution, inhalation exposure and human health. However, despite India’s high plastic consumption, rapid urbanization, and severe particulate air pollution burden, atmospheric microplastics remain comparatively underexplored. This review combines a thematic literature review and a systematic bibliometric analysis of Indian airborne microplastic studies published between 2017 and 2025 to assess the existing evidence on major sources, atmospheric behaviour, meteorological influences, human exposure pathways, and emerging research trends. The findings suggest that the textile-derived fibres, traffic-related emissions, road dust resuspension, industrial activities, and indoor dust are the primary sources of airborne MPs, whereas wastewater systems, urban runoff, agricultural soils, and fragmented environmental plastic reservoirs contribute to long-term secondary redistribution. It has also been observed that their atmospheric transport and deposition are strongly influenced by meteorological factors. Available exposure estimates suggest that inhalation may account for an intake of approximately 325 to 863 microplastic particles per person per day within Indian metropolitan regions. Experimental and toxicological findings also suggest that MPs could trigger oxidative stress, inflammatory reactions and disruption of the epithelial lining. The bibliometric analysis further demonstrates a rapid growth in airborne microplastic research after 2020, with increasing emphasis on toxicity, human health, remediation, and atmospheric pathways. Although exposure quantification, atmospheric modelling, and epidemiological investigations remain underrepresented, major challenges also persist regarding standardized monitoring, contamination control, polymer identification, and size-resolved exposure assessment, highlighting the need to incorporate airborne microplastics into existing air-quality monitoring frameworks to support long-term surveillance, standardized exposure assessment, and future regulatory development.

The dawn of a new air pollutant: inhalable microplastics as emerging vectors of hazardous contaminants and their implications for human health
AI summary Read the abstract
Researchers measured tiny inhalable microplastics in the air across four major Indian cities and found concentrations high enough that an average person could accumulate nearly 3 grams in their lungs over a lifetime. Polyester fibers from textiles were the most common type detected, and the particles were also found to carry harmful chemicals, heavy metals, and even pathogenic microorganisms. The study highlights airborne microplastics as an emerging air pollutant with potential health implications.
Atmospheric microplastics: Global status with emphasis on studies from Indian environments
AI summary Read the abstract
This review pulls together years of global research on microplastics floating in our air, finding that most studies come from Asian countries—especially China—while India, despite having some of the world's most polluted cities, has surprisingly little research on this topic. Since we breathe air constantly, airborne microplastics are a potential health concern worth understanding, but this paper highlights that scientists in developing countries like India need to catch up on studying what's actually in the air people are inhaling. The takeaway: we don't yet have enough data to fully understand the risks in heavily polluted, high-population regions, which is a gap that needs addressing for public health planning.
Microplastics in Atmospheric Fallout of Delhi: Unveiling the Hidden Threats of Urban Pollution and Emerging Risks
AI summary Read the abstract
Researchers tracked tiny plastic particles falling from Delhi's air over four months and found the amount tripled from October to January, with busy residential areas getting nearly double the plastic fallout of quieter suburban zones. Most of these particles were tiny plastic fibers from common materials like polyester and packaging plastics, small enough to potentially be inhaled deep into your lungs. Since this pollution is worsening and we breathe this air daily, the findings signal a growing health concern that needs more research and stronger pollution policies in major cities.
Microplastics in the urban atmosphere: Sources, occurrences, distribution, and potential health implications
AI summary Read the abstract
This review summarizes research on airborne microplastics in cities, finding that indoor sources like textiles and outdoor sources like traffic-related plastic particles are major contributors. Microplastic concentrations in urban air can be significant, especially in densely populated areas, and people can inhale these particles daily. The health implications of breathing in microplastics are still being studied, but early evidence suggests they may cause lung inflammation and other respiratory problems.
