The Way of Macroplastic through the Environment

et al. 2020

With the focus on microplastic in current research, macroplastic is often not further considered. Thus, this review paper is the first to analyse the entry paths, accumulation zones, and sinks of macroplastic in the aquatic, terrestrial, and atmospheric environment by presenting transport paths and concentrations in the environment as well as related risks. This is done by applying the Source–Pathway–Receptor model on macroplastic in the environment. Based on this model, the life cycle of macroplastic is structurally described, and knowledge gaps are identified. Hence, current research aspects on macroplastic as well as a sound delimitation between macro- and microplastic that can be applied to future research are indicated. The results can be used as basic information for further research and show a qualitative assessment of the impact of macroplastic that ends up in the environment and accumulates there. Furthermore, the applied model allows for the first time a quantitative and structured approach to macroplastic in the environment.

“…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.…”

“…Based on the literature review for MP sampling in Indian beaches, it is observed that variable sampling procedures were used by different researchers. Sampling was done using forceps, non-plastic spoon, spatula, tweezers or shovel from quadrants of various sizes like 25 × 25 cm 2 , 30 × 30 cm 2 , 50 × 50 cm 2 , 1 × 1 m 2 and 2 × 2 m 2 (Jayasiri et al 2013a ; Veerasingam et al 2016a , b ; Dowarah and Devipriya 2019 ; Sathish et al 2019 , 2020c ; Ashwini and Varghese 2019 ; Jeyasanta et al 2020b ; Sundar et al 2020 ; Maharana et al 2020 ; Robin et al 2020 ). Collection of deep sea sediment samples was preferably done using a vessel and specialized equipment including the Van Veen grab sampler, the Peterson grab sampler and a box corer (Sruthy and Ramasamy 2017 ; Goswami et al 2020 ; Jeyasanta et al 2020a ; James et al 2020 ; Patterson et al 2020 ).…”

“…The present understanding of MP prevalence in the marine biota suggests that a significant proportion of organisms are at risk of ingesting these synthetic polymers which can lead to variable levels of health complications. Studies have found that due to the increasing exposure to MPs, marine biota can experience oxidative stress, reduction in filtration capacity, inflammation in tissues, impaired digestive tract, pseudo-satiation and reduced immunity (Dowarah et al 2020 ; Maharana et al 2020 ; Daniel et al 2020 ; Sathish et al 2020b ). In India, studies on ingestion of MPs by fishes have been a major attraction for the researchers.…”

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.

“…Marine debris in the ocean is an emerging global environmental concern and increasing marine debris all along the coasts. It has been found in the pelagic environment worldwide and their quantity is increasing at an alarming rate, posing many threats to the coastal and marine environment (Maharana et al, 2019;Nisanth and Kumar, 2019). Over the past five or six decades, contamination and pollution of the world's enclosed seas, coastal waters and the wider open oceans by marine debris has been an ever-increasing phenomenon.…”

Marine debris was collected monthly from substations along Panvel creek from May 2020 to April 2021 and was analyzed for types of non-plastic debris and plastic debris. Plastic debris was assessed for % composition of a type of plastic, plastic polymer and further categorized according to plastic code, acronym, full name and common examples. Non-plastic debris of 8 types representing 38 items were recorded. Consumer and manufactured items like glass and plastic bottles, cans, bags, rubber, metal, fiberglass, cigarettes, fishing gears etc. were observed. 8 types of polymers representing 65 items were recorded along Panvel creek. Plastic polymers like Polyethylene terephthalate (PETE/PET), High density polyethylene (HDPE), Polyvinyl chloride (PVC), Low density polyethylene (LDPE), Polypropylene (PE), Polystyrene (PS), Polyamide/Nylon, Acrylonitrile Butadiene Styrene (ABS) and Polyurethane (PU) were recorded. 13 items belongs to Plastic code 2:HDPE, 12 to 3:PVC, 11 to 5:PP, 9 to 6:PS, 8 to 4:LDPE, 6 to 1:PETE/PET and 3 each to 7:PA and Other and 8:PU, respectively, were documented. Maximum % composition (20.00%) of HDPE, and minimum (4.61%) of PA and Other and PU, respectively was recorded. Higher content of debris recorded is attributed to the disposal of domestic wastes intentionally or unintentionally into the creek and also for disposal of scrap materials from the fishing crafts. Higher HDPE content is attributed to the wastes released from the fishing vessels and also to the domestic and municipal wastes. At present the Panvel creek is moderately polluted and 3R i.e. reduce, reuse and recycling is the current solution to the overuse of plastics.
