“…Ingress of microplastics into the aquatic systems occurs through disparate sources and pursue multiple pathways (Browne 2015;Browne et al 2008). The sources relate to the manufacturing of plastic products (Fadare et al 2020), water (Sighicelli et al 2018;Luo et al 2019) and sewage treatment plants (Ziajahromi et al 2016), industrial or agricultural wastes (Deng et al 2020;Wang et al 2020a), weathering of plastics (Eo et al 2018), fisheries, or aquaculture (Zhang et al 2017;Xue et al 2020;Zhang et al 2020b) that may enter into the marine system affecting the aquatics (Harmon 2018;de Sá et al 2018;Xu et al 2020). Table 1 shows the microplastic abundance, types, and source of various locations Plastic wastes from households, industries, etc.…”

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.

“…In addition to polyolefins and polystyrene, polyethylene terephthalate (PET) plays a pivotal role in the global packaging market, especially for fresh food, water and soft drinks (Ellen MacArthur Foundation, 2016). Moreover, PET contributes more than 70% to the global production of synthetic fibres which are majorly used for the textile industry (Geyer, et al , 2017) and can end up as microplastics pollution in the natural environments (Deng, et al , 2019; Zhang, et al , 2019).…”

Summary Polyethylene terephthalate (PET) is a mass‐produced synthetic polyester contributing remarkably to the accumulation of solid plastics waste and plastics pollution in the natural environments. Recently, bioremediation of plastics waste using engineered enzymes has emerged as an eco‐friendly alternative approach for the future plastic circular economy. Here we genetically engineered a thermophilic anaerobic bacterium, Clostridium thermocellum, to enable the secretory expression of a thermophilic cutinase (LCC), which was originally isolated from a plant compost metagenome and can degrade PET at up to 70°C. This engineered whole‐cell biocatalyst allowed a simultaneous high‐level expression of LCC and conspicuous degradation of commercial PET films at 60°C. After 14 days incubation of a batch culture, more than 60% of the initial mass of a PET film (approximately 50 mg) was converted into soluble monomer feedstocks, indicating a markedly higher degradation performance than previously reported whole‐cell‐based PET biodegradation systems using mesophilic bacteria or microalgae. Our findings provide clear evidence that, compared to mesophilic species, thermophilic microbes are a more promising synthetic microbial chassis for developing future biodegradation processes of PET waste.

“…We chose polyester fibers for the present study, since they are predominantly used in the global textile production in fabrics for apparel, garments, and other finished textiles [37]. Accordingly, polyester fibers are the most common fiber polymer polluting natural water systems [1,[38][39][40]. We used red-pink polyester fibers, which also showed strong autofluorescence with red filter settings (excitation 511-551 nm, emission 573-613 nm), since they are easy to distinguish in color and shape from other natural or worn fibers that might occur as contaminants in the laboratory.…”

Microplastic fibers are frequent contaminants of aquatic ecosystems. Early life stages of aquatic organisms are predicted to be especially vulnerable to microplastic pollution. We hypothesized that microplastic fibers in the water column might interfere with fertilization and embryonic development of fish. We tested this with an in vitro fertilization system with three-spined sticklebacks. Six egg clutches were divided and one half was fertilized and bread out in water with polyester fibers (PET fibers; mean diameter 9.7 ± 2.3 μm; mean length 245.6 ± 163.1 μm) at a concentration of 1 × 104 fibers/L while the other half served as control without fibers.Observation with a dissection microscope revealed that some polyester fibers stuck to the outside of the eggs in the fiber treatments. Yet, overall 67.4 ± 12.9% eggs were fertilized from which 97.2 ± 4.2% larvae hatched without any significant difference between treatments. Mortality and abnormal development of larvae was low and was not changed by microplastic fibers, as was the heart rate of developing embryos five days post fertilization.The present study illustrates that polyester fibers, even at concentrations three to four orders above levels reported from the environment, do not impair fertilization success, embryonic and early larval development of sticklebacks. Accordingly, concentrations of microplastic fibers currently observed in aquatic habitats do not appear to be harmful to early live stages of fish.
