“…Adverse effects of microplastics on shes have been found in many literatures (Jacob et al, 2020;Abhijit et al,2021;Anna et al,2021). Due to the attractive color, buoyancy, and food-like properties, sh are particularly prone to ingesting microplastics (Garrido Gamarro et al, 2020). The ingestion of microplastics by sh can cause a variety of consequences: 1) microplastics can lead to physical damage and histopathological alterations (Peda et It is wildly acknowledged in the literatures that the ingestion, accumulation and elimination of microplastics in shes are species-speci c (Mizraji et al, 2017;Xu and Li, 2021), which was also veri ed with our previous studies Zhang et al, 2021).…”

Microplastics contamination have been extensively reported in aquatic ecosystem and organisms. It is wildly acknowledged that the ingestion, accumulation and elimination of microplastics in fishes are species-specific, which mainly depending on the feeding behavior. This study aims to investigate the effects of microplastics on the morphology and inflammatory response in intestines of fishes with different feeding types. Largemouth bass (carnivorous fish), grass carp (herbivorous fish) and Jian carp (omnivorous fish) were used as organism model. The contributing concentration and size of microplastics are explored as well as the response time and legacy effect in fishes. Two different sizes of polystyrene microplastics (8 μm and 80 nm) were set at three concentrations. And samples were analyzed at different exposure times and depuration times. Histological analysis indicated that multiple abnormalities in intestines are presented in three species fishes after acute exposure microplastics. The mRNA abundance of immune-related genes in the intestine tissues of fishes were significantly induced or restrained. There were differential expressions of genes coping with differential sizes and concentrations of microplastics exposure in different fishes. The reason for the difference effects of microplastics on fishes was still unclear but could be due to the difference in the structure and function of the digestive system. These results provide a theoretical basis to further analysis of the mechanism of fish intestinal pathology caused by microplastics.

“…In the past years, reviews have been published about MPs pollution in fish, mainly referring to marine species [44,45], or discussed together with other environmental compartments in well defined geographical areas, like the Meditteranean sea [46], the Indian coasts [47], or the Yellow sea in China [48]. Others are related to the possible health risk for humans due to the consumption of fish and seafood [49][50][51]. Finally, many tried to summarize the results obtained from laboratory trials [35,[52][53][54].…”

Microplastics (MPs) have received increasing attention in the last decade and are now considered among the most concerning emerging pollutants in natural environments. Here, the current knowledge on microplastic ingestion by wild freshwater fish is reviewed with a focus on the identification of possible factors leading to the ingestion of MPs and the consequences on fish health. Within the literature, 257 species of freshwater fishes from 32 countries have been documented to ingest MPs. MPs ingestion was found to increase with rising level of urbanization, although a direct correlation with MPs concentration in the surrounding water has not been identified. MPs ingestion was detected in all the published articles, with MPs presence in more than 50% of the specimens analyzed in one study out of two. Together with the digestive tract, MPs were also found in the gills, and there is evidence that MPs can translocate to different tissues of the organism. Strong evidence, therefore, exists that MPs may represent a serious risk for ecosystems, and are a direct danger for human health. Moreover, toxicological effects have also been highlighted in wild catches, demonstrating the importance of this problem and suggesting the need for laboratory experiments more representative of the environmental situation.

“…Similarly, Rist et al (2018) highlighted that food and beverages likely only constitute a minor exposure pathway to human microplastic exposure. Based on the current knowledge on microplastics in seafood, there is no evidence that food safety is compromised (Gamarro et al 2020).…”

Seafood is an important food source, and this chapter addresses the food safety concerns related to plastic particles in different seafood. Here we focus on those species which are commonly consumed by humans, such as bivalves, gastropods, cephalopods, echinoderms, crustaceans, and finfish. The objectives of this chapter are to (1) outline the major sources, fate, and transport dynamics of microplastics in marine ecosystems, (2) provide a critical assessment and synthesis of microplastics in seafood taxa commonly consumed by humans, (3) discuss the implications of microplastics with regard to human health risk assessments, and (4) suggest future research priorities and recommendations for assessing microplastics in marine ecosystems in the context of global food security and ocean and human health.
