Occurrence of microplastics in gastrointestinal tract of fish from the Gulf of Guinea, Ghana
Summary
Researchers examined the gastrointestinal tracts of commercially important fish species from the Gulf of Guinea, Ghana, for microplastic contamination. The study found that 68% of the fish contained microplastics, with fibers being the most common type, raising concerns about potential human exposure through seafood consumption in the region.
Over the past decades, there has been a growing concern about microplastics pollution in global aquatic habitats and its potential impact on human health. This study was carried out to determine the presence of microplastics in fish of economic importance in Ghana. Microplastics were found to be abundant in all investigated samples, with 68 % of the fishes contaminated with microplastics and a total of 133 plastic items identified in the fish. The presence of fibers, black coloured particles, and microplastics in the size range of 0.5-1.0 mm was the most abundant in the samples examined. Three polymers specifically, polyethylene, polyvinyl acetate, and polyamide were identified in the study. The presence of microplastics in the fishes investigated may pose severe ecological and health concerns, and hence comprehensive policies targeted at preventing plastic pollution of Ghana's maritime environment is warranted.
