“…Microplastics have been found in the air we breathe (Enyoh et al 2019), in the food we consume (Eerkes-Medrano et al 2019;Zhang et al 2020c, b), or in the soil where our crops grow (Corradini et al 2019). They were discovered on peak of Everest (Napper et al 2020) and at the depths of the deep ocean (Zhang et al 2020a;Courtene-Jones et al 2020). In humans, existence of microplastics in human stool (Schwabl et al 2019) and for the first time MP fragments in human placenta (Ragusa et al 2021) were confirmed.…”

Graphical abstract Surging dismissal of plastics into water resources results in the splintered debris generating microscopic particles called microplastics. The reduced size of microplastic makes it easier for intake by aquatic organisms resulting in amassing of noxious wastes, thereby disturbing their physiological functions. Microplastics are abundantly available and exhibit high propensity for interrelating with the ecosystem thereby disrupting the biogenic flora and fauna. About 71% of the earth surface is occupied by oceans, which holds 97% of the earth’s water. The remaining 3% is present as water in ponds, streams, glaciers, ice caps, and as water vapor in the atmosphere. Microplastics can accumulate harmful pollutants from the surroundings thereby acting as transport vectors; and simultaneously can leach out chemicals (additives). Plastics in marine undergo splintering and shriveling to form micro/nanoparticles owing to the mechanical and photochemical processes accelerated by waves and sunlight, respectively. Microplastics differ in color and density, considering the type of polymers, and are generally classified according to their origins, i.e., primary and secondary. About 54.5% of microplastics floating in the ocean are polyethylene, and 16.5% are polypropylene, and the rest includes polyvinyl chloride, polystyrene, polyester, and polyamides. Polyethylene and polypropylene due to its lower density in comparison with marine water floats and affect the oceanic surfaces while materials having higher density sink affecting seafloor. The effects of plastic debris in the water and aquatic systems from various literature and on how COVID-19 has become a reason for microplastic pollution are reviewed in this paper.

“…We also suggest that the methods recommended here will require tailoring to the required sample size to ensure maximum efficiency, as particularly the canola oil method may require different ratios of reagents for larger sample volumes. 56 Little impact was seen on the identication of microplastics treated with the method reagents, with the majority of HQIs above 0.7. This was expected as reagents were chosen for their previously reported low impact on plastic particles.…”

“…Floating marine plastic pollution is estimated at around 250,000 tonnes, although this is thought to only reflect around 1% of the total amount of plastic that has entered the marine environment over the past 60-70 years and much of the "missing" plastic may be within the water column and within marine sediments (Mountford and Morales Maqueda, 2019;van Sebille et al, 2020). Both empirical data and the use of numerical modelling have shown that plastics have pervaded remote regions of the world's oceans, from deep sea sediments (Courtene-Jones et al, 2020;Peng et al, 2020) to remote islands (Lavers and Bond, 2017) and both poles (Lusher et al, 2015;Waller et al, 2017). Recently, microplastics (plastic particles smaller than 5 mm in diameter) have also been discovered in sea ice at concentrations comparable to those at the sea surface within "garbage patches" (Peeken et al, 2018).…”

Marine plastic pollution was first documented in the 1970s but has gained attention and popularity both within the scientific community and with the general public over the past decade. Despite public awareness of the issues associated with plastic pollution and a societal shift toward a reduction in single-use plastics, global plastic production reached 359 million tonnes in 2018 (PlasticsEurope, 2019), of which between 4.8 and 12.7 million tonnes are thought to enter the marine environment (Jambeck et al., 2015). Floating marine plastic pollution is estimated at around 250,000 tonnes, although this is thought to only reflect around 1% of the total amount of plastic that has entered the marine environment over the past 60-70 years and much of the "missing" plastic may be within the water column and within marine sediments (Mountford & Morales Maqueda, 2019; van Sebille et al., 2020).
