Panacea for the nanoplastic surge in Africa: A state-of-the-art review
AI summary Read the abstract
This review examines the nanoplastic pollution crisis across Africa, where improper plastic waste management has led to widespread contamination of water, soil, sediments, air, and food from fragmented and biodegraded plastics. The review evaluates existing and emerging mitigation strategies and calls for region-specific policy and technological solutions to address the rapidly growing nanoplastic burden across the continent.
Africa is a large continent ranked amongst the top consumer of plastic materials. However, the improper handling of plastic wastes has resulted in massive pollution of different aspects of the environment (water, soil, sediments, air, food, etc.) within and around the region. The fragmentation and biodegradation of the bulk plastic material into small-sized particles has given rise to microplastic and nanoplastics. Owing to their small sizes, ease of transport, and large surface area, they tend to wreak serious havoc in the environment. Nevertheless, the growing awareness of the pollution problems caused by micro/nanoplastic debris is instrumental towards circumventing its widespread across the ecosystem. This review provides a state-of-the-art information on the prevailing nanoplastic surge across the borders of Africa, the ineffective management policies of plastic wastes, potential environmental hazards, and possible remediation strategies. Additionally, prospective insights into new areas for advanced research were highlighted.

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.
Macro problems from microplastics: Toward a sustainable policy framework for managing microplastic waste in Africa
AI summary Read the abstract
Researchers critically reviewed regulatory and policy approaches to managing microplastic pollution across African countries. They found that while environmental monitoring studies demonstrate an urgent need for action, the effectiveness of existing plastic waste policies in Africa remains poorly understood. The study proposes a sustainable policy framework tailored to the unique challenges African nations face in reducing microplastic waste generation and environmental contamination.

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.
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.
