“…Jang et al observed that in a rural coastal location in Korea, polypropylene, which is used to make fishing nets and ropes, was more abundant than at both an urban site and an aquafarm. A larger relative abundance of polypropylene in coastal waters of rural areas compared to urban areas was also confirmed by Kwon et al [209], who also observed a predominance of expanded polystyrene, a material commonly used to float marine gear for fishing and aquaculture activities [209,211].…”

Plastic Pollution, Waste Management Issues, and Circular Economy Opportunities in Rural Communities

Rural areas are exposed to severe environmental pollution issues fed by industrial and agricultural activities combined with poor waste and sanitation management practices, struggling to achieve the United Nations’ Sustainable Development Goals (SDGs) in line with Agenda 2030. Rural communities are examined through a “dual approach” as both contributors and receivers of plastic pollution leakage into the natural environment (through the air–water–soil–biota nexus). Despite the emerging trend of plastic pollution research, in this paper, we identify few studies investigating rural communities. Therefore, proxy analysis of peer-reviewed literature is required to outline the significant gaps related to plastic pollution and plastic waste management issues in rural regions. This work focuses on key stages such as (i) plastic pollution effects on rural communities, (ii) plastic pollution generated by rural communities, (iii) the development of a rural waste management sector in low- and middle-income countries in line with the SDGs, and (iv) circular economy opportunities to reduce plastic pollution in rural areas. We conclude that rural communities must be involved in both future plastic pollution and circular economy research to help decision makers reduce environmental and public health threats, and to catalyze circular initiatives in rural areas around the world, including less developed communities.

“…A survey conducted in Korean coastal waters found the abundance of microplastics near urban areas, and the polymer composition differed by depth, based on the size and density of particles, with a high load of lowdensity microplastics in the bottom water samples as a result of biological interactions (Song et al, 2018). A recent water sample analysis conducted in the surface water from six semi-enclosed bays and two coastal waters in Korea found the region-specific occurrence of microplastics due to differences in human activities near urban and rural areas, but the distribution of microfibers was uniform throughout the study area (Kwon et al, 2020).…”

The accumulation of plastic products in the terrestrial and aquatic environment is one of the major concerns in recent years. The quality of the ecosystem is affected globally due to the large production, ubiquitous usage, and poor plastic waste disposal. Plastic debris is categorized based on its size as macroplastics, mesoplastics, microplastics, and nanoplastics, respectively. Microplastics are the emerging contaminant that occurs in varying shapes like tiny beads, spheres, films, fragments, fibres, and filaments. The use of microplastics in cosmetics and abrasion from large plastic items including textile fibres and tyres are suspected to contaminate the environment when it reaches the aquatic ecosystem. Indian coastal waters are polluted by microplastics owing to industrialization, overpopulation, tourist and maritime activities. Many species of fishes, reptiles, birds, and mammals are directly threatened by entanglement or ingestion, and some marine mammals consume a large amount of microplastic debris by raptorial feeding thereby leads to trophic transfer. Humans are considered as the most exposed organisms than other vertebrates as they occupy at the top of the food chain. Certain government legislations have been put forth to ban some products that are considered as the major contributor to plastic debris. Recently, the use of bioplastics is increased all over the world to replace microplastics in industrial and commercial products. However, there is little awareness of the microplastic pollutants among the public, thus the main motive of this review is to provide public awareness and responsibility to limit the use of plastics that adversely damage our environment

“…Both primary and secondary plastics contribute to global NP/MP pollution in aquatic environments due to their persistency and buoyancy. MPs have been detected worldwide in oceanic compartments, including surface water [ 16 , 17 ], deep sea, seabed [ 18 , 19 ], and shorelines [ 20 ], as well as polar regions and remote islands [ 21 , 22 ]. In marine ecosystems, concentrations of MPs have been reported to be up to 100,000 particles m −3 [ 23 ].…”

“…As environmental concentrations of MPs in marine ecosystems range from 0.04 particles m −3 (Portuguese coast) [ 17 ] to markedly higher concentrations, such as in Hong Kong (51–27,909 particles m −3 ) [ 48 ], the North Yellow Sea of China (545 ± 282 particles m −3 ) [ 49 ], the Yangtze estuary (4137.3 ± 2461.5 particles m −3 ) [ 50 ], the southeastern coastline of South Africa (257.9 ± 53.36–3308 ± 1449 particles m −3 ) [ 51 ], and Cape Cod to the Caribbean in the Atlantic (6.06 × 10 3 –8.32 × 10 5 particles m −3 ) [ 52 ], the concentration range employed in this study was set to cover environmental and relatively higher concentrations. Thus, the potential effects of the combination of Cr(VI) and MPs were estimated in response to environmental concentrations (1, 10, and 100 particles L −1 ) of MPs alone, Cr(VI) alone, and Cr(VI) combined with different concentrations of MPs by measuring endpoints established for each animal, such as survival, growth, offspring, and other physiological responses.…”

The prevalence of hexavalent chromium [Cr(VI)] and microplastics (MPs) is ubiquitous and is considered a threat to aquatic biota. MPs can act as a vector for waterborne metals; however, the combined effects of Cr(VI) and MPs on aquatic organisms are largely unknown. In this study, aquatic model animals, such as rotifers (Brachionus calyciflorus and B. plicatilis), water fleas (Daphnia magna), amphipods (Hyalella azteca), polychaetes (Perinereis aibuhitensis), and zebrafish (Danio rerio) were exposed to environmental concentrations (1, 10, and 100 particles L−1) of 1 μm polystyrene MPs alone, Cr(VI) alone, or Cr(VI) combined with MPs. Following exposure, the potential effects were measured by analyzing basic life endpoints (e.g., survival rate and growth). A significant response to MPs alone was not observed in all animals. However, MPs combined with Cr(VI) concentration-dependently increased Cr(VI) toxicity in two rotifer species. The survival rate of water fleas was significantly reduced upon exposure to Cr(VI) + MPs (100 particles L−1) compared with exposure to Cr(VI) alone, and significantly decreased the number of offspring. Although there was no significant effect on the body length of the amphipod, concentration-dependent decreases in their survival rates were observed. In contrast, no significant change was found in the survival rate of polychaetes; however, their burrowing ability was inhibited by Cr(VI) + MPs (100 particles L−1). Further, larval mortality was increased in response to Cr(VI) + MPs (100 particles L−1) in zebrafish. Taken together, the findings suggest that MPs can exacerbate Cr(VI) toxicity, even at environmental levels.
