Bird’s-eye view of per- and polyfluoroalkyl substances pollution research in the African hydrosphere
Summary
This study used data analytics to map PFAS pollution across African aquatic ecosystems, finding that urbanization, GDP growth, and population increases are the primary drivers of contamination — a pattern consistent with broader global trends as Africa's economy expands and use of fluorinated industrial chemicals rises.
The surge in Africa’s economy has led to increased use of per- and polyfluoroalkyl substances (PFASs), resulting in environmental pollution. This has spurred regulatory and research efforts to mitigate these impacts. We used data analytics to study PFAS pollution in aquatic ecosystems in Africa and model PFAS concentrations using socio-economic variables. In agreement with literature, urbanization, gross domestic product, and population growth drive PFAS pollution.
