“…The content of microplastics in fresh waters has been verified in previous studies,, including the rivers Danube [ 60 ], Elbe, Mosel, Neckar and Rhine in Germany [ 61 ], Vembanad Lake in India [ 62 ], Dongting Lake and Hong Lake in China [ 63 ] or the Chishui River in China [ 59 ]. MPs in fresh water and groundwater have their sources on land.…”

“…For this reason, it is important to thoroughly observe fresh water and groundwater for the presence of microplastics. Plastic waste settled in river basins is often a source of pollution in the rivers and lakes to which plastic waste is transported and can be accumulated [ 31 , 59 ]. Most studies focus on microplastics in the oceans, but it is equally important to investigate inland water too, where the content of MPs is likely to be similar.…”

Plastic particles smaller than 5 mm, i.e., microplastics, have been detected in a number of environments. The number of studies on microplastics in marine environments, fresh water, wastewater, the atmosphere, and the human body are increasing along with a rise in the amounts of plastic materials introduced into the environment every year, all contributing to a range of health and environmental issues. Although the use of primary microplastics has been gradually reduced by recent legislation in many countries, new knowledge and data on these problems are needed to understand the overall lifecycle of secondary microplastics in particular. The aim of this review is to provide unified information on the pathways of microplastics into the environment, their degradation, and related legislation, with a special focus on the methods of their sampling, determination, and instrumental analysis. To deal with the health and environmental issues associated with the abundance of microplastics in the environment, researchers should focus on agreeing on a uniform methodology to determine the gravity of the problem through obtaining comparable data, thus leading to new and stricter legislation enforcing more sustainable plastic production and recycling, and hopefully contributing to reversing the trend of high amounts of microplastics worldwide.

“…Microplastics has been categorized into various basic shapes such as fragments, fibres, films, foams, and beads. Most of the time, fibres were found to be the most prevalent microplastic shape type (Firdaus et al, 2020;Li et al, 2021;Napper et al, 2021). Many studies have reported that fragment types can dominate aquatic environments (Baini et al, 2018;Khalik et al, 2018;Yaranal et al, 2021).…”

“…One of the most prominent anthropogenic aspects of microplastic pollution is the improper disposal of plastic trash, which has accelerated the accumulation of microplastics in aquatic environments (Geyer et al, 2017). Plastics that are broken down into micro particles can easily spread into fresh and marine aquatic habitats (Firdaus et al, 2020;Li et al, 2021;Bharath et al, 2021;Napper et al, 2021), creating difficult problems.…”

Microplastic is defined as plastic debris with a size less than 5mm. It is characterized based on colour, shape, and polymer type. Microplastics have been discovered in a variety of aquatic environments, including freshwater, estuarine, and marine waters. The presence of microplastic in aquatic systems poses a threat not only to aquatic organisms, but to human consumers of food harvested from these environments. This paper reviews the key characteristics of microplastics, how they contaminate aquatic ecosystems, and their effects on aquatic organisms. Efforts have been made to highlight the knowledge gaps in these areas and measures that deserve attention for addressing the problem.

“…Hence, there have been progressively more studies investigating the distribution and abundance of microplastics in the freshwater environment (e.g., water, sediments, and biota) of China in the recent years [5,8,19] . For example, Huang et al [19] (2020) and Pan et al [20] (2020) clearly described the abundance, shape, chemical composition, and size distribution of microplastics in the Zhangjiang River and West River. Wang et al [5] (2020) not only evaluated the microplastics in Beijiang surface water but also detected microplastics in fish samples.…”

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.
