Micro plastics are found almost everywhere on Earth, from deep ocean sediments, to remote mountain lakes and in atmospheric fallout.
Professor Henk Bouwman and his team at the Unit for Environmental Sciences and Management at North West University found microplastics, too, in rivers running through developed parts of Gauteng and in the North West.
They collected and filtered 46 fresh water samples from various localities in and around Gauteng.
“High levels of plastic pollution were found in almost all samples. Up to 40 plastic particles per litre were found in the surface water of the Vaal River, a major river in the country’s largest drainage basin flowing through industrialised areas,” Bouwman and colleagues Carina Venter and Karin Minnaar write for a poster, “Cause and Effects of Plastics in SA as a Developing Country”.
These levels, they say, are comparable to high levels of microplastic pollution found in European rivers.
