“…It also indicates the data where polymers are yet to be identified in MPs [17]. Table 1 [18] lists the concentrations, shapes, and types of MPs present in some of the east and west coast regions of India along with the assessment technique utilized to identify and separate them. It can be referred from Fig.…”

“…This leads to the accumulation of plastics in the environment at a staggering rate, and as a result, we are producing about 300 million tons of plastics every year worldwide, where half of it comes from single-use items. Recently, India has banned the usage of single-use plastics [18]. This needs to be further effectively enforced across all the nations at a global level.…”

The term "microplastics (MPs)" refers to solid particles of size less than 5 mm made of non-biodegradable polymers like PE, PP, and PET. In India, plastics account for around 60% of the overall municipal solid waste generated, finding an easy way to drift into the river bodies and deteriorating water quality. MPs pose a potential threat to the biosphere. MPs can be classified based on their origin and morphology. These characteristics can be used to find an efficient technique for assessing MPs. This review discusses various analytical techniques for monitoring MPs from surface water bodies with their advantages and limitations.

“…The research interventions in freshwater systems, terrestrial systems, atmosphere and human consumables are lacking significantly at present, demanding a greater focus as these resources are equally important to us. Based on the present literature survey, three review articles concerning the presence of MPs in different environmental matrices of India were published by Veerasingam et al ( 2020 ), Sarkar et al ( 2020 ) and Pandey et al ( 2021 ). The present review is an attempt to further add on to the available knowledge.…”

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.

Microplastic particles are found in environmental compartments all over the world and receive a great deal of attention, especially in the aquatic environment. Currently, a particularly high input of microplastics via Asian rivers is assumed, but so far, there are hardly any data through field measurements. Three rivers in South India were considered for this purpose to focus on their microplastic load. The emphasis was on the comparison of microplastic concentrations in urban and rural rivers. While two rivers in the megacity Chennai (Tamil Nadu) were found to have an average microplastic concentration of 0.4 microplastic particles/L, a rural river near Munnar (Kerala) had an average concentration of 0.2 microplastic particles/L. Rough estimates of annual microplastic discharge from the Adyar River (Chennai) into the Bay of Bengal are found to be as high as 11.6 trillion microplastic particles. This study should be one of the first baseline studies for microplastic loads in South Indian streams and should be complemented with further environmental sampling before, during and after the monsoon season to get more detailed information on the storage and transportation of fluvial microplastics under different weather conditions.
