“…A summary of MPs detected in Indian terrestrial systems is shown in Table 5 . The dust samples in these studies were collected from outdoor (Patchaiyappan et al 2020b ) and indoor (Zhang et al 2020 ) systems, and significant abundance of MPs was found, indicating the ubiquitous reach of these particles. According to the study conducted by Zhang et al ( 2020 ), the estimated ingestion of MPs originating from the dust samples in different age groups (adults, teenagers, toddlers and infants) is 770–10,000 ng/kg bw/day (PET-based MPs) and 0.88–11.00 ng/kg bw/day (PC-based MPs).…”

“…With increased consumption of plastic items in our daily lives, their ageing and subsequent fragmentation leads to leaching of MPs in our terrestrial systems. The sources of these MPs can include mismanaged plastic waste, tyre wear and tear, fragmentation of construction and building materials, or aeolian transport of MPs from widespread sources (Patchaiyappan et al 2020b ). A summary of MPs detected in Indian terrestrial systems is shown in Table 5 .…”

The increased production and consumption scale of plastic items has led to the generation of microplastics (MPs), an emerging class of contaminants, in our environment. MPs are plastic particles less than 5 mm in size and could originate due to primary and secondary sources. The primary ones are generated as such in the MP size range while the secondary MPs are a result of fragmentation of larger plastic particles which eventually enters the aquatic, terrestrial and atmospheric environments. The increasing concern of MP pollution in every compartment of our environment is being globally explored, with relatively fewer studies in India. Among the total studies published on MP prevalence in the Indian environments, marine systems have received significantly higher attention compared to the other compartments like freshwater, atmosphere, terrestrial and human consumables. This review article is an effort to present current understanding of MP pollution in aquatic systems, terrestrial systems, atmosphere and human consumables of India by reviewing available scientific literature. Along with this, the review also focuses on identification of the gap areas in current knowledge and highlights way forward for future research. This would further help in meeting the goals of this emergent pollutant management.

“…3). In another study from Chennai, India, mostly fragments and bers were resulted from the street dust samples (Patchaiyappan et al 2021). Similarly in Iran the street dust samples of city and county of Asaluyeh, MPs of bers, fragments, spherules and lms were noticed (Abbasi et al 2019).…”

Microplastics (MPs) are ubiquitous in our environment. Its presence in air, water and soil makes it a serious threat to living organisms. The present study aimed to assess the availability of MPs in air and street dust of a metropolitan city Varanasi, India. Suspended dust samples and street dust samples were collected from various sampling sites. The assessment of MPs was conducted by for physical identification binocular microscopy, fluorescence microscopy and Scanning Electron Microscopy (SEM), while elemental analysis done by Energy Dispersive X-Ray Analysis (EDX). and finally, Fourier-transform infrared spectroscopy (FTIR) was used for functional group analysis. the presence of MPs in both suspended dust and street dust samples of all selected sampling sites was confirmed by results. MPs of different color with the shape of Fragments, Films, Spherules and Fibers were observed in the study. However, most of the MPs were less than 1mm in size. The MPs identified in our study were majorly polypropylene, polystyrene, polyethylene, polyethylene terephthalate, polyester, and polyvinyl chloride. EDX analysis showed presence of trace elements like aluminum, cadmium, magnesium, sodium, and silicon apart from carbon and oxygen, which indicates the presence of additives or adsorption capacity of MPs. Confirmation of MPs in the air of a locality of Varanasi explains the need of deep research in this concerned field to protect our future from negative impacts of breathing MPs.

“…Many studies about PAHs in road dust showed that HMW-PAHs were the most abundant PAHs [91,92]. On the other hand, MPs were also reported to have high concentration in road dust and could be possible carriers for PAHs [93]. Nevertheless, the study of Ida [94] also reported high MPs concentration on roads and in nearby stormwater, sweep sand, and wash water.…”

Microplastic pollution has become a worldwide concern. However, studies on the distribution of microplastics (MPs) from inland water to the ocean and their affiliated polycyclic aromatic hydrocarbons (PAHs) are still limited in Vietnam. In this study, we investigated the distribution of MPs and PAHs associated with MPs in canals, Saigon River, and Can Gio Sea. MPs were found at all sites, with the highest average abundance of MPs being 104.17 ± 162.44 pieces/m3 in canals, followed by 2.08 ± 2.22 pieces/m3 in the sea, and 0.60 ± 0.38 pieces/m3 in the river. Fragment, fiber, and granule were three common shapes, and each shape was dominant in one sampling area. White was the most common MP color at all sites. A total of 13 polymers and co-polymers were confirmed, and polyethylene, polypropylene, and ethylene-vinyl acetate were the three dominant polymers. The total concentration of MPs-affiliated PAHs ranged from 232.71 to 6448.66, from 30.94 to 8940.99, and from 432.95 to 3267.88 ng/g in Can Gio sea, canals, and Saigon River, respectively. Petrogenic sources were suggested as a major source of PAHs associated with MPs in Can Gio Sea, whereas those found in Saigon River and canals were from both petrogenic and pyrogenic sources.
