Microplastic pollution in surface water from east coastal areas of Guangdong, South China and preliminary study on microplastics biomonitoring using two marine fish
AI summary Read the abstract
Researchers investigated the abundance, distribution, and characteristics of microplastics in coastal surface waters from eastern Guangdong, South China, and evaluated two marine fish species (Konosirus punctatus and Mugil cephalus) as bioindicators for microplastic biomonitoring. The study documented microplastic contamination across sampling sites and assessed species-specific differences in microplastic ingestion as a monitoring tool.
Microplastic pollution, one of the major global challenges, is a severe threaten to aquatic organisms. The purpose of this study was to investigate the abundance, distribution and characteristics of microplastics in coastal surface waters from eastern Guangdong, south China. We chose pelagic Konosirus punctatus and demersal Mugil cephalus from different sampling sites as candidate monitoring species for the ingestion of marine microplastics, and talked about the relationship between water samples and fish samples. We tried to find out the regulation about microplastics characteristics in fish samples and fish own traits. The mean abundance of microplastics in surface water was 8895 items/m, small white fragments were dominating character. We need to increase the amount of fish data to further explore. This study would not only provide a detailed reference for a better understanding of microplastic pollution in Guangdong coastal areas, but also shed an insight in prospect of using fish as biomonitoring of microplastic wastes.

Microplastics were found in two economically important freshwater fish species sampled across Guangdong Province, China, with fibers being the most common type and polypropylene and polyester the dominant polymers. The widespread contamination of commercial freshwater fish in China indicates a significant pathway for human exposure through fish consumption.
Microplastic accumulation in fish from Zhanjiang mangrove wetland, South China

Microplastics were found in multiple fish species collected from Zhanjiang mangrove wetlands in South China, with contamination levels and particle types varying by species and feeding behavior. The study highlights how microplastics accumulate in fish living in mangrove ecosystems and enter coastal food chains.
Occurrence of Microplastics in the Gastrointestinal Tract and Gills of Fish from Guangdong, South China
AI summary Read the abstract
Researchers analyzed microplastic contamination in the gastrointestinal tracts and gills of eight commercial fish species from coastal Guangdong, China. They found an average of 6.6 microplastic particles per fish, with fibers under 1 mm being the most common type, and noted that herbivorous and omnivorous fish accumulated more microplastics in their digestive systems than carnivorous species.
