“…Atmospheric dynamics include suspension, transport and deposition of MP and NP. The main sources are urban, industrial and agricultural activities [21,22,36,37] and traffic [38][39][40], while secondary sources, like erosion of contaminated soils [41] and suspension of MP from the ocean during bubble bursting [42], should also be taken into account. Figure 1 reports the main sources and transport pathways of MP and NP.…”

“…9721)). Besides, the active collection requires a pump for aspiration of air through filters with well-defined mesh, as usually performed for atmospheric particulate matter [53,54] and as described for airborne MP [37,42,55]; sampling devices with sequential filters with decreasing mesh size are also available (cascade impactor). Commonly, to avoid contaminations, sampling is performed using quartz fiber or polytetrafluoroethylene filters.…”

“…Indeed, both hydrogen peroxide and the Fenton reaction produce hydroxyl radicals, which were shown to react efficiently with some NP [50]. For this reason, separation and purification steps have not been employed in several studies, however this might increase the difficulties in the detection and the identification of MP [34,37,42,55].…”

“…Liu et al [55] and Wang et al [42] investigated atmospheric MP over the west Pacific Ocean and the South China Sea and the east Indian Ocean, respectively. Their results show a lower concentration of MP in aerosol over open ocean, compared to the concentration measured in urban sites (Table 2).…”

“…However, they carefully estimate that, once in the atmosphere, suspended MP are transported passively by complex two-and three-dimensional physical winds, resulting in a large variability over the land and surface ocean. In particular, Wang et al [42] performed a statistical analysis and highlight that four meteorological factors limit the distribution of MP: (i) wind speed is needed for MP transport, (ii) gust velocity is necessary to suspend MP from the ground or the sea surface, (iii) humidity and (iv) low pressure (strong turbulence) have an important effect on MP transport. They also infer that the atmospheric MP over the ocean might originate not only from the adjacent continent but also from the adjacent oceanic atmosphere polluted by other continental MP emissions.…”

Atmospheric plastic pollution is now a global problem. Microplastics (MP) have been detected in urban atmospheres as well as in remote and pristine environments, showing that suspension, deposition and aeolian transport of MP should be included and considered as a major transport pathway in the plastic life cycle. This work reports an up to date review of the experimental estimation of deposition rate of MP in rural and urban environment, also analyzing the correlation with meteorological factors. Due to the limitations in sampling and instrumental methodology, little is known about MP and nanoplastics (NP) with sizes lower than 50 µm. In this review, we describe how NP could be transported for longer distances than MP, making them globally present and potentially more concentrated than MP. We highlight that it is crucial to explore new methodologies to collect and analyze NP. Future research should focus on the development of new technologies, combining the existent knowledge on nanomaterial and atmospheric particle analysis.

Increasing micro plastic concentration in the marine environment is a severe threat to the marine ecosystem and indirectly to human society depending on the marine environment. Also, the surface and subsurface water quality parameters are the indicators of the usability of the water sources for human activities. The primary source of micro plastic is the water river systems from land to sea. This study establishes a correlation between water quality parameters and micro plastic concentration to find the most suitable quality parameter for finding the micro plastic concentration in urban coastal estuaries of Chennai coast, Tamil Nadu, India. Twenty samples from Adyar and Cooum estuaries were collected, with ten each on August 2019 and August 2020. They are tested for temperature pH, EC, Turbidity, TDS, DO, BOD, COD, Salinity and micro plastic concentrations. Correlation tests such as Pearson's and Spearman's are performed based on the initial Normality and Homogeneity test. The results show that all the parameters are significantly not correlated with the Micro plastic Concentration, and Micro plastic Concentration is considered an independent factor.
