“…Although the sampling methods are different, the main shapes of the microplastics in the freshwater of China are similar, mostly fibers and fragments that account for more than 60% of the total microplastics. The main source of fiber and fragments is the decomposition of plastic containers such as plastic bags, fishing nets, and lines [22][23][24] . At the same time, the size of most of the microplastics, in the freshwater of China, is smaller than 1 mm as shown in Table 1.…”

“…Though transparent and white colors are the main colors of the detected microplastics in Chinese rivers. As shown in Table 1, the abundance of microplastics in the Yellow River, Yangtze River, and Pearl River Delta, which are the three main rivers in China, is significantly higher than the abundance of the Qiantang River, Minjiang River, and other rivers [5,23,[25][26][27] . The surrounding population of these three rivers is dense, and the degree of urbanization and economic development is higher than other regions of China, indicating the microplastic pollution could be closely related to the society and economy of the freshwater neighborhood.…”

“…The average abundance of microplastics in the sediment of freshwater were ranging between 460 and 10240 items/kg or 0 to 1292 items/m 2 as can be seen from Table 2. More severe microplastics pollution levels were found in the sediments of West River, Pearl River, Danjiangkou Reservoir, and Minjiang (Chengdu) [19,23,36,42] . Similar to water, the main shapes of microplastics in sediments are fragments and fibers as shown in Table 2.…”

In the last few years, the pollution of microplastics in freshwater environments such as rivers, lakes, and reservoirs has aroused widespread concerns. In this review, rich and appropriate data on microplastics, in the freshwater ecosystem of China, was collected. Following this microplastics in surface waters, sediments, and biota, of the freshwater system, were thoroughly analyzed. The results show that microplastics are widespread in the freshwater environment of China. At the same time, the abundance of microplastics is positively correlated with both intensive human activities and urbanization. The risk index of microplastics is relatively high in the water of Yellow River (654 items/L), Yangtze River (9.20 × 105 items/km2), and Pearl River regions (7571 items/m3). The prevalent shapes of microplastics, in water and sediments, are fragments and fibers. Moreover, the particle size of microplastics is mainly less than 2 mm. In fact, PP and PE are found to be the main polymer types in the freshwater environment of China. Bivalves and freshwater fish are the main research objects of microplastics pollution in China. In parallel to that, the abundance of microplastics, in each aquatic organism, varied from a few to a dozen. Additionally, the characteristics of microplastics in organisms are mainly fibers smaller than 1 mm. Fundamentally, the key two sources of microplastics, in the freshwater environment of China, are wastewater discharge and surface runoff. It is noteworthy that microplastics, in a freshwater environment, does not only cause environmental pollution but harms aquatic organisms, too. Finally, microplastics can reach the human body, through the food chain, causing potential health issues.

“…Recently, microplastics have been detected in the vertical direction of various marine and lake sediment (e.g., Southern Ocean regions, the Tokyo Bay, Gulf of Thailand, and the Wuliangsuhai Lake in China) [2,11,12]. Studies have shown that microplastics may be preserved in deep sediment, and the amounts may be even larger than surface sediment and overlying waters [13,14]. For instances, a study by Xue et al [13] has documented that the storage of microplastics in the sediment (-5 to -60 cm) is 5 times more than that in the surface sediment in the Beibu Gulf of China.…”

“…The Taihu Lake is the third largest freshwater lake in China, while it has suffered various environmental pollution during recent decades, including algal blooms, the contamination of heavy metals and organic pollutants [16,17]. Recent studies have also shown that microplastics could be detected in a wide range area of the Taihu Lake [14,18,19]. To date, the reported studies mainly focus on the distribution of microplastics in the surface sediment of the Taihu Lake [14,18], while the research on the vertical distribution of microplastics in the sediment of this lake is rare.…”

Microplastics are ubiquitous in the freshwater environment, while its abundance in the sediment profiles has received little attention. The vertical microplastic distribution in the sediment of the North (NTH) and Southwest (SWTH) Taihu Lake were identified and characterized in this study. Microplastics could be detected at all depths (0–50 cm) at the two sites, with the total abundance of 8066 and 5333 particles kg-1 dry weight sediment at NTH and SWTH, respectively. This indicates that the microplastic storage in the sediment of the Taihu Lake may be underestimated, if only the surface sediment is considered. Microplastics composed of various polymer types were identified in the sediment of the two sites, including polyamide (PA), acrylic acid (AA), polyethylene terephthalate (PET) and cellulose acetate (CA), while high density polyethylene (HDPE) and polypropylene (PP) were only detected at NTH. The main type of polymers detected at NTH (42%) and SWTH (43%) were PA. The majority shape of microplastics was fibers, with a ratio of 76% and 78%, respectively at the site NTH and SWTH. The colors of microplastics were mainly white (accounted for 42% and 43% at NTH and SWTH, respectively), which may be caused by the long-term decomposition of dyestuff in the syngenesis of sediment and/or probably the degradation during sample treatments. The textile industry and fishery activities may provide the source. In summary, our findings in the Taihu Lake favors to understand the microplastic pollution and tackle microplastics challenges.
