“…Most of the microplastics found in the sediments of the Tisza and its tributaries were fibres (94-98%). Similarly, fibre-dominated sediments were reported in the Fall and Six Mile Creeks in the USA (Watkins et al, 2019), in the Solimoes, Negro and Amazon Rivers in Brazil (Gerolin et al, 2020), and in the Haine and West Rivers in China (Liu et al, 2021;Huang et al, 2021aHuang et al, , 2021b. On the other hand, in the sediments of the River Thames in the UK (Horton et al, 2017) and the Nakdong River in South Korea (Eo et al, 2019), mostly microplastic fragments were found, and microbeads dominated in the St. Lawrence River in Canada (Crew et al, 2020), while spheres and fragments were both common in the sediments of the Elbe River in Germany (Scherer et al, 2020).…”

“…The comparison of our data to other data from all over the world also suggests that the sediments of the Tisza River system are polluted by microplastics. For example, in the Haihe River in China, 4980 ± 2462 items/kg microplastic particles were deposited (Liu et al, 2021); in the West River in China, 2560-10,240 items/kg were found (Huang et al, 2021a(Huang et al, , 2021b; in the Nakdong River in South Korea, 1970 ± 62 items/kg were counted (Eo et al, 2019); in three rivers of the Amazon system in Brazil, 417-8178 items/kg were found (Gerolin et al, 2020); in the Brisbane River in Australia, 10-520 items/kg were found (He et al, 2020a); in the Canadian St. Lawrence River, 65-7562 items/kg were counted (Crew et al, 2020); and in the Fall and Six Mile Creeks in the USA, ca. 25-250 items/kg were found (Watkins et al, 2019).…”

“…During their route, plastics degrade, and this degradation is driven by sunlight (ultraviolet radiation), pH, temperature, physical weathering caused by friction, oxidative weathering, and biodegradation by microorganisms (Li et al, 2020, Huang et al, 2021a, 2021b. The physical and chemical degradation of large plastic items can be a slow process, lasting from a half century to over a millennium (Chamas et al, 2020); therefore, plastics may persist in the environment for a long time.…”

Microplastics are a new type of persistent organic pollutants, usually on the micron scale. In this study, we investigated the abundance, distribution, and other characterization of microplastics in surface waters of the Wei River Basin in the Shandong peninsula. The results showed that the abundance of microplastics in the surface water of Wei River varied from 0.40 to 1.20 items/L, and the average abundance was 0.81 items/L, which was at a moderate pollution level compared with other rivers. It was found that the abundance of microplastics was higher in densely populated areas, and hydrodynamic conditions such as river inflow and seawater scour also affected the abundance of microplastics. Fiber (83.4%) was the dominant type. Colorless (93.6%) was the dominant color type. The particle size (0.06 - 0.5mm) (47.9%) was the main size of microplastics in the Wei River. This study provides data for the further study of microplastics in rivers and provides a warning for the management and prevention of microplastics in freshwater.

“…Microplastics were separated from the sediment using the method of separation by density conducted in Martins and Sobral (2011). Firstly, sediments were dried in oven (60 ℃, 48 h) and then sieved through a 5 mm sieve (Jahan et al, 2019). Plastics > 5 mm were discarded.…”

In freshwater ecosystems, previous studies on microplastics have been mostly focused on natural rivers and lakes, with limited consideration of urban water source areas. Sediments, recording the steady process of microplastics accumulation during a long period of time, can act as an important sink for microplastics. In this study, we investigated the distribution, characteristics and ecological risks of microplastic contaminants in sediments of a water supply reservoir of Hefei City (the Dafangying Reservoir). Meanwhile, the differences of microplastic concentrations in sediments between the rural and urban areas were also compared. The average microplastics abundance of sediments in rural areas was 83.20 ± 32.99 n/100g dry weight (dw), and 182.67 ± 72.21 n/100g (dw) in urban areas. The total microplastic concentrations were significantly higher in sediments of urban sites than that in rural sites (p < 0.01), which can be ascribed to more complex and diverse microplastic sources triggered by intensive anthropogenic activity in cities. Specifically, we also demonstrated significantly higher microbead abundance (p < 0.01) in urban sites, which may result from the widespread use of microbead in personal care products. Our results detected five shapes (fibers, debris, films, foams and microbeads) and seven colors (white, black, transparency, red, blue, green and brown) of microplastics in sediments of the Dafangying Reservoir, with fibers and transparency accounting for the dominant shape and color, respectively. Given the complexity and diversity of microplastics in urban areas, we exhibited a relatively higher abundance of microplastics in the Dafangying Reservoir than that in other rural larger reservoirs. According to the index of geoaccumulation, the sedimentary microplastics were assessed as moderately polluted. Our study provides valuable references for microplastic contaminants in urban water supply reservoir, and highlights the importance of microplastics assessment in aquatic ecosystems.
