“…The MPs were all composed of fibrous MPs and long strips, with no debris or pellets. Li et al 38 also found that fibrous MPs were the major components of the MPs in the lake sediments of the middle and lower reaches of the Yangtze River Basin. Therefore, the length instead of the particle size was used to classify the MPs.…”

Anthropocene 8,27,33,35 , but there is still lack of sufficient studies about (micro)plastics abundance and characteristics versus time. We selected the second-largest urban lake in China, Donghu Lake, as the study area and collected a sediment column. The MPs with a detection limit of 100 μm versus time were studied by the 210 Pb chronological data, Raman Spectrometer identification and scanning electron microscope. The changes in MPs abundance, length, colour, polymer type, and surface features over time were studied, and the possibility of using MPs as an indicator of the Anthropocene was discussed.

“…MPs are generally considered to be plastic particles smaller than 5 mm (Cole et al 2011). Commonly, the sources of MPs in the environment are from the direct emissions of primary MPs and from degradation of the large plastics in the environment (Wang et al 2017), and the destination of most MPs in the environment are the sediments of aqueous ecosystem (Li et al 2019;Zhao et al 2019a) and terrestrial ecosystem (Baeza et al 2020). Regarding the ocean MPs, the major sources which have been extensively studied are the decomposition of marine plastic waste, import of land-based plastic waste, disposal of plastic waste from marine vessels, abandonment of aquaculture industry's floating devices and other sources (Law & Thompson 2014;Thompson 2015;Auta et al 2017;Boucher & Friot 2017).…”

According to the statistics, 8.3 billion metric tonnes of plastics have been produced since 1950s, which is far more than other synthetic materials and the annual production which are about 500 million tonnes per year at present. The production of plastics makes microplastics pollution extremely widespread distribution, which will have a lasting impact on the global environment, especially on the aquaculture systems. And the distribution of the microplastics is extremely imbalanced around the global waters. In the present review, we have summarized the development of aquaculture in the World and China based on the existing data sources. And the total aquaculture production of the World will over 90 million tonnes, which will exceed the capture production in 2020. Aquaculture products will become one of the most important sources of high-quality protein. However, we found that many kinds of microplastics are detected and enriched in both farmed and captured species. Both endogenous and exogenous factors like the use of fishing plastic products, factory farming facility and equipment, natural and synthetic feed, animal health products, aquaculture fortifier and aquatic food additives make accumulation of microplastics easier. In addition, the safety of aquaculture products is closely related to human health because the residues of microplastics in fish leading to various potential hazards. In summary, this paper reviewed the relationship between microplastics and aquaculture, aimed at calling for the rational and restricted use of plastic products in the aquaculture ecosystems.

“…Moreover, microplastic concentrations are often presented in units that unduly inflate recorded values. Despite regularly collecting ≤30 L of water, the majority of suspended and floating riverine microplastic surveys published in 2019 reported microplastic concentrations per m 3 , a unit two orders of magnitude greater than their sample volume, regularly presenting concentrations that equate to <1 particle L −1 (Di, Liu, Wang, & Wang, 2019; Li et al, 2019) (Table 1). Such extrapolation would be rightly considered unacceptable for other pollutants.…”

Mismanaged plastic waste poses a complex threat to the environments that it contaminates, generating considerable concern from academia, industry, politicians, and the general public. This concern has driven global action that presents a unique opportunity for widespread environmental engagement beyond the immediate problem of the persistence of plastic in the environment. But for such an opportunity to be realized, it is vital that the realities of plastic waste are not misrepresented or exaggerated. Hotspots of plastic pollution, which are often international in their source, present complex environmental problems in certain parts of the world. Here we argue, however, that the current discourse on plastic waste overshadows greater threats to the environment and society at a global scale. Antiplastic sentiments have been exploited by politicians and industry, where reducing consumers' plastic footprints are often confused by the seldom-challenged veil of environmental consumerism, or "greenwashing." Plastic is integral to much of modern day life, and regularly represents the greener facilitator of society's consumption. We conclude that it
