Occurrence and accumulation of microplastics in commercial fish in the coastal waters of the Lvsi fishing ground in China
AI summary Read the abstract
Researchers examined microplastics in the gills and guts of 11 commercial fish species from a Chinese coastal fishing ground, finding that over 85% of fish contained microplastics in these tissues at levels of roughly 2–3 pieces per fish. PET fibers with a blue color were most common, and microplastic abundance did not increase with trophic level, suggesting limited biomagnification in this food web. Because many of these fish species are consumed by humans, understanding their microplastic loads is directly relevant to assessing human dietary exposure.
In recent years, there has been an exponential increase in the research popularity of microplastics (MPs) in offshore marine environments. However, there is still a gap in the research on the accumulation of MPs in different tissues of aquatic organisms and the trophic transfer of MPs between aquatic organisms. The common occurrence of MPs in the gills and guts of 11 species of commercial fishes was examined in the coastal waters of the Lvsi fishing ground (LSFG). The obtained results showed that >85 % of MPs existed in the gills and guts of these fish, and the abundance was 2.39 ± 1.38 pieces/fish and 2.56 ± 1.42 pieces/fish, respectively. Fibrous and blue are the most common colors and shapes of MPs, and PET is the main polymer type. At the species level, the abundance of MPs in the gills and guts of a few fishes (e.g., Larimichthys polyactis, Setipinna tenuifilis, Collichthys lucidus) decreased with increasing body length and body weight (P < 0.05). At the community level, this situation was not significant (P > 0.05). With increasing trophic level (TL), MPs tended to decrease in the gills (trophic magnification factor, TMF = 0.86) but did not significantly vary in the gut. We believe that MPs are multidimensional pollutants, and their accumulation in tissues/organs of organisms has not been accurately and qualitatively determined. To establish the relationship of MP transport and trophic transfer among water, sediments and organisms, we suggest that more efforts should be made to investigate MPs in aquatic organisms in the coastal waters of LSFG and to increase the examination of MPs in the water column and sediments. This study will help us improve our understanding of MPs pollution, and provide a good reference and basis for the management, monitoring and implementation of pollutants in marine organism of coastal water.

AI summary Read the abstract
By examining microplastics in individual fish of two Sciaenidae species from Chinese coastal waters, this study found that MP abundance increased with fish body length, suggesting potential biomagnification at the individual level. Most MPs were blue PET fibers, reflecting contamination from textile waste, and the findings highlight the risk of MP accumulation in commercially important fish species.
