Researchers found microplastics in the digestive systems and gills of six Scombridae fish species collected from coastal waters near Karachi, Pakistan, providing preliminary evidence of microplastic contamination in commercially important marine fish from the region.

Body Systems

Microplastics are one of the major pollution problems nowadays, have been found in both marine environments and various fish species worldwide. In this study, the presence of microplastics in the digestive systems and the gills of 6 species from the Scombridae family on the coast of Karachi in Pakistan was investigated. A total of 336 fish were examined for the presence of microplastic in gills and the digestive systems. Microplastics were detected in digestive systems and gills in 11.11%-19.51% and 58.62%-85.71% of total individuals, respectively. The number of microplastics varied from 0.19 to 1.12 items.ind-1 in digestive system and 1.5 to 7.04 items.ind-1 in gill. Fibre was dominant in both gills (98.67-99.17%) and digestive systems (100%). More extensive and further investigations are needed on microplastic contamination of the biota on the Pakistan coast.

Researchers found microplastics, mainly polyethylene and polypropylene, in the guts of fish from the Swat and Kabul rivers in Pakistan. These rivers are primary freshwater sources for the region, and the contaminated fish are regularly consumed by local communities. The findings confirm that freshwater fish from polluted rivers are a pathway for microplastic exposure in people's diets.
