Ecological consequences of microplastic pollution in sub-Saharan Africa aquatic ecosystems: An implication to environmental health
AI summary Read the abstract
This review examines the ecological consequences of microplastic pollution in aquatic ecosystems across sub-Saharan Africa, where research on the topic remains limited. Researchers summarized evidence that microplastics have been found in water, sediment, and aquatic organisms throughout the region, with potential effects on food chains and human health. The study highlights the urgent need for more comprehensive monitoring and policy responses in African countries.
Microplastic pollution (MPs) emerged as a significant environmental concern due to its persistent nature. These MPs particles endure in waters, soils, and even the atmosphere, posing potential threats to the entire ecosystem. Aquatic organisms are at risk of ingesting MPs, leading to accumulation in tissues, ultimately affecting entire food chain. This study aims to provide an overview of sources of MPs, distribution, and potential environmental impacts. MPs have been documented in various substances such as bottled water, salts, seafood, and even the air. However, the full extent of the health consequences on human exposure remains uncertain. Therefore, it is imperative that we draw public attention to the presence of these pollutants in the environment. To mitigate adverse effects of MPs, reducing plastic consumption, implementing improved waste management practices, and advocating sustainable behaviors are essential for well-being of natural ecosystems and the health human populations.

Microplastic pollution in aquatic environments in Africa: status and research opportunities
AI summary Read the abstract
This review examines the status of microplastic pollution research in African aquatic environments, noting that Africa's high rate of plastic waste mismanagement has resulted in widespread contamination of freshwater and marine ecosystems. Researchers found significant research gaps in the region despite its outsized contribution to global plastic pollution, and identified opportunities for expanded monitoring given microplastics' capacity to adsorb persistent organic pollutants.
Microplastics in African ecosystems: Current knowledge, abundance, associated contaminants, techniques, and research needs
AI summary Read the abstract
This review synthesized current knowledge on microplastic abundance, associated contaminants, and ecological effects in African ecosystems, a region that ranks among the highest in mismanaged plastic waste. Despite the scale of the problem, the review found insufficient environmental monitoring data from Africa, calling for continent-specific research to support accurate global risk assessments.

AI summary Read the abstract
This review summarizes the current state of microplastic pollution across the African continent, covering water, soil, and air environments. Researchers found that rapid industrialization and urbanization are increasing the rate of microplastic contamination, but significant knowledge gaps remain about the extent and impacts of this pollution in African countries. The study highlights the need for more research on the ecological and health risks of microplastics in the region.
Plastic and Micro/Nanoplastic Pollution in Sub-Saharan Africa: Challenges, Impacts, and Solutions
AI summary Read the abstract
This review documents the growing microplastic and nanoplastic pollution problem across sub-Saharan Africa, where rapid plastic use and poor waste management are creating significant contamination in waterways, sediments, and aquatic life. The harsh climate conditions in the region accelerate plastic breakdown into smaller, more dangerous particles. The pollution threatens food production, water quality, and public health in communities that often lack the resources to monitor or address the problem.
A review of the ecotoxicological status of microplastic pollution in African freshwater systems
AI summary Read the abstract
This review summarizes existing research on microplastic pollution in African rivers and lakes, finding contamination in water, sediments, and fish across the continent. Fibers and fragments were the most common shapes, and the study notes that microplastics can enter body cells and cause genetic mutations, oxidative stress, and nerve damage -- a concern given that Africa's freshwater microplastic monitoring and drinking water research remain limited.
