Marine and freshwater microplastic research in South Africa
AI summary Read the abstract
This review summarizes microplastic research in South Africa, noting that both marine and freshwater studies are still limited but growing. The review highlights key knowledge gaps, particularly in freshwater environments, that need to be addressed to understand the extent of South Africa's microplastic contamination.
South Africa has a vibrant plastics manufacturing industry, but recycling is limited and insufficient with a notable proportion of the unmanaged waste entering the environment. South Africa is a developing country with microplastics research in its inception. Very little is known about freshwater microplastics, and studies on South African marine microplastics are limited but actively being pursued. In a water-scarce country, protection of freshwater resources remains a priority, but in the face of other socioeconomic issues (poverty, unemployment, and HIV/AIDS), it receives insufficiently effective attention. The full impact and risks of microplastics pollution in water is yet to be discovered. The risks may be enhanced in a developing country where many communities remain largely dependent on the land and natural waters. With South Africa being a water-scarce country, the quality of its aquatic resources is at an even greater risk with an assumed increasing background of microplastics, emphasizing the need for further research. A South African Water Research Commission-funded project is being undertaken to derive research priorities, but there is an immediate need for improved recycling and waste management.

Microplastic occurrence and fate in the South African environment: a review
AI summary Read the abstract
This review summarizes microplastic contamination across South Africa's freshwater, marine, and air environments. Researchers found microplastics in drinking water samples from major cities, with marine sediment levels along the southeast coast reaching particularly high concentrations. The findings emphasize the need for better wastewater treatment, stronger laws on single-use plastics, and more research on how this contamination affects human health.
Plastics in municipal drinking water and wastewater treatment plant effluents: challenges and opportunities for South Africa-a review.
AI summary Read the abstract
This review examines the limited research on plastic pollution in South African freshwater and drinking water systems compared to the country's more studied coastal and marine environments. The authors identify a significant knowledge gap on the health and economic impacts of plastics in water supplies and call for more monitoring and policy development.
The Occurrence and Fate of Microplastics in Wastewater Treatment Plants in South Africa and the Degradation of Microplastics in Aquatic Environments—A Critical Review
AI summary Read the abstract
A review of microplastic research in South Africa reveals a critical data gap: despite the country generating around 120 million tons of waste annually, there is almost no published information on microplastic concentrations in its wastewater treatment plants or freshwater systems. The authors argue that urgent monitoring is needed to support effective policy, given that South Africa's infrastructure is under increasing pressure from urbanization and industrialization.
A review of the environments, biota, and methods used in microplastics research in South Africa
AI summary Read the abstract
This review assesses the current state of microplastic research in South Africa, finding that while the country leads the African continent in publications, many studies use inconsistent methods that limit comparability. The authors call for a standardized national approach to microplastic sampling and analysis, noting that terrestrial and atmospheric environments remain largely uninvestigated.
Microplastics in South African Aquatic Environments: A Systematic Review of Spatial Distribution, Analytical Methods, and Research Trends (2012–2025)
AI summary Read the abstract
This review pulls together 28 studies to show that microplastics, tiny plastic bits from broken-down waste, are widely present in South Africa's rivers, coastlines, and even wastewater, but research has mostly focused on a few coastal cities while inland areas remain a blind spot. Since these plastics have been found in water and food sources people rely on, and South Africa currently has no official rules for tracking or limiting them, this matters for making sure contamination doesn't go unnoticed or unmanaged. The takeaway: we know microplastics are out there, but inconsistent testing methods and gaps in monitoring mean the full picture
