Characterisation of Ingested Microplastic Particles and Textile Microfibres in the Gastrointestinal Tract of Demersal Fish from a Peri-Urban Open Access Lagoon in Lagos Nigeria
Researchers characterized microplastic particles and textile microfibres in the gastrointestinal tracts of demersal fish from multiple genera caught in a peri-urban lagoon bordering Lagos, Nigeria. They found evidence of microplastic ingestion across multiple fish species, contributing to the limited but growing body of data on microplastic exposure in West African aquatic food webs.
Pervasive Microplastic Ingestion by Commercial Fish Species from a Natural Lagoon Environment
Researchers examined microplastic contamination in the gastrointestinal tracts and gills of commercial fish species from a natural lagoon environment. Microplastics were found across all species examined, with fiber morphotypes dominant and contamination levels reflecting the lagoon's proximity to human activity and plastic pollution sources.
Levels and Classification of Microplastics and Their Impact on the Wellbeing of Selected Commercially Important Fish Species in Kisumu Bay, Lake Victoria
A study in Kenya's Lake Victoria found microplastics in the digestive tracts of 65% of fish sampled across four commercially important species, including Nile perch and tilapia. Given that these species are important sources of dietary protein for millions of people in East Africa, the findings raise direct human health concerns about plastic ingestion through fish consumption and call for stronger environmental protections in African freshwater systems.
Abundance and characteristics of microplastics in major urban lakes of Dhaka, Bangladesh
Researchers measured microplastic contamination in three major urban lakes in Dhaka, Bangladesh, finding plastic particles in the water, sediment, and fish at all sites. The dominant plastics were common consumer types like polyethylene and PVC, with sizes mostly under 100 micrometers. Since these lakes are in a densely populated urban area, the findings raise concerns about microplastic exposure for the local population through both water and fish consumption.
Assessment of microplastics in water and sediment from Megech river, major tributary to Lake Tana
Researchers surveyed microplastic contamination in the Megech River in Ethiopia, finding an average of 0.55 microplastic particles per liter in surface water and 19.39 particles per kilogram in sediment, with higher concentrations near urban areas. This baseline study highlights how growing plastic use in developing nations is reaching even freshwater systems in East Africa.
