“…A large part of the population of India lives in coastal areas, which contribute to the production of large amounts of marine litter. Some of the research on debris monitoring evaluations carried out along different parts of the Indian shoreline indicates that ineffective waste management, principally in coastal region, as well as population behavior is one of the fundamental causes of marine litter pollution ( Sulochanan et al, 2019 ; Jeyasanta et al, 2020 ; Krishnakumar et al, 2020 ; Sathish et al, 2020 ; Vidyasakar et al, 2020 ; Mugilarasan et al, 2021 ). In India, the first confirmed case of COVID-19 was recorded in Kerala on January 30, 2020.…”

“…Many studies have investigated debris at local or regional scales (e.g., Wessel et al, 2019;Miladinova et al, 2020;Vidyasakar et al, 2020) These studies are predominately carried out along the coastal margin (Serra-Gonçalves et al, 2019) though studies along rivers and at river outlets are becoming more common (e.g., Battulga et al, 2019;Cordova and Nurhati, 2019;Van Calcar and Van Emmerik, 2019). However, these empirical studies are, by necessity, restricted to a limited area, so in order to understand debris distribution on a broader scale, modeling and predictions are critical.…”

There have been a variety of attempts to model and quantify the amount of land-based waste entering the world’s oceans, most of which rely heavily on global estimates of population density as the key driving factor. Using empirical data collected in seven different countries/territories (China, Kenya, South Africa, South Korea, Sri Lanka, Taiwan and Vietnam), we assessed a variety of different factors that may drive plastic leakage to the environment. These factors included both globally available GIS data as well as observations made at a site level. While the driving factors that appear in the best models varied from country to country, it is clear from our analyses that population density is not the best predictor of plastic leakage to the environment. Factors such as land use, infrastructure and socio-economics, as well as local site-level variables (e.g., visible humans, vegetation height, site type) were more strongly correlated with plastic in the environment than was population density. This work highlights the importance of gathering empirical data and establishing regular monitoring programs not only to form accurate estimates of land-based waste entering the ocean, but also to be able to evaluate the effectiveness of land-based interventions.

“…MPs in these beaches arise due to different natural and anthropogenic sources. Anthropogenic sources include fishing, tourism, recreational, religious, port and industrial activities, mismanaged plastic waste and untreated wastewater discharges while natural sources include surface and wind currents, aeolian processes, run-off and riverine transport (Jayasiri et al 2013b ; Balasubramaniam and Phillott 2016 ; Veerasingam et al 2016b ; Karthik et al 2018 ; Vidyasakar et al 2018 , 2020 ; Tiwari et al 2019 ; Maharana et al 2020 ; Robin et al 2020 ). A significant majority of MPs found in these studies are irregularly shaped fragments.…”

“…For extraction of MPs, wet peroxide oxidation and density separation were the most preferably used methods. In some studies, prior to density separation, treatment with acids like hydrochloric acid was also given in order to remove the carbonates (Vidyasakar et al 2020 ). For density separation, sodium chloride (NaCl) was found to be the most commonly used salt whereas zinc bromide (ZnBr 2 ), zinc chloride (ZnCl 2 ), sodium iodide (NaI), calcium chloride (CaCl 2 ) and sodium bromide (NaBr) were preferred for the separation of heavier polymers (Tiwari et al 2019 ; Sathish et al 2019 ; Patterson et al 2019 , 2020 ).…”

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.
