Quantitative and qualitative determination of microplastics in oyster, seawater and sediment from the coastal areas in Zhuhai, China

Occurrence of microplastics in wild oysters (Crassostrea tulipa) from the Gulf of Guinea and their potential human exposure

“…According to predictions made in the Ghana National Plastic Action Partnership (2021) report, for instance, the amount of plastic that leaks into the nation's water bodies is expected to rise by 190%, from about 78,000 tonnes per year in 2020 to 228,000 tonnes per year by 2040. Under suitable biophysical and environmental conditions, the majority of the plastic waste in terrestrial and aquatic systems disintegrates into small particles called microplastics (plastic particles from 1 μm to 5 mm) ( ISO, 2020 ), which could be easily ingested by organisms such as invertebrates and fish ( Wang et al., 2021 ).…”

“…Oysters are good bioindicators of aquatic pollution because their unique feeding strategy allows them to filter large amounts of water through their gills, thereby exposing the organisms to filamentous microplastics found in aquatic media ( Wang et al., 2021 , Wang et al., 2021 ; Teng et al., 2019 ). The mangrove oyster is a popular seafood choice in West Africa and may be found in many of the region's estuaries and lagoons.…”

“…Several studies have reported microplastic ingestion and toxicity in marine organisms from various ecosystems worldwide ( Lerebours et al., 2022 ; Said et al., 2022 ; Zhang et al., 2022 ; Wang et al., 2021a; 2021b ; Li et al., 2018 ; Martinelli et al., 2020 ; Patterson et al., 2019 ; Teng et al., 2019 ; Bour et al., 2018 ; Digka et al., 2018 ; Li et al., 2018 ; Murphy 2018 ; Renzi et al., 2018 Avio et al., 2015 , Cauwenberghe et al., 2015 ; De-Witte et al., 2014 ) with little information on their impact on human health when consumed. Nonetheless, the extent of exposure and toxicity may vary depending on environmental conditions and geographic location.…”

Microplastic pollution in finless porpoises and their habitats along the Fujian coast of the East China Sea

“…MPs are distributed globally, especially in marine environments, where they occur in coastal (Zhu et al, 2020) to pelagic waters, the surface sea (Lorenz et al, 2019) to the deep-sea (Woodall et al, 2014;Monteiro et al, 2018), marine sediments (Zhao et al, 2018;Zhang et al, 2020), and even in the polar regions (Lusher et al, 2015a;Mishra et al, 2021). Coastal areas of China are known to have levels of microplastic pollution (Zhao et al, 2014;Cheung et al, 2016;Fok et al, 2017;Zhang et al, 2020;Wang et al, 2021a).…”

Methods of Analyzing Microsized Plastics in the Environment

“…Sci. 2021, 11, 10640 2 of 13 seas to the poles [11,12]. It has been reported that plankton, which lie on the lowest tropic level in the marine ecosystem, ingest microplastics as food.…”
