Résumé
Per- and polyfluoroalkyl substances (PFAS) are organic pollutants that may have adverse effects on the ecosystem. Despite the global presence of PFAS, knowledge of PFAS on the African continent is limited because monitoring of PFAS is challenging and often not feasible owing to the lack of analytical capacity and high cost. However, it is necessary to understand the environmental risks posed by these chemicals in developing countries, because increasing urbanization will likely increase PFAS contamination in the environment. Although, as far as is known, PFAS concentrations in the African aquatic environment are generally lower than in more developed countries, exceedances of ecological quality standards (EQS) were reported in a few cases, providing evidence of potential ecological risks to these ecosystems. However, the number of ecosystems at risk will likely increase as urbanization and modernization increase in African countries. Therefore, environmental regulations should be updated and implemented to reduce further contamination of the aquatic environment with these chemicals. In addition, analytical laboratories in Africa should develop their capacity to detect PFAS and related compounds regularly and routinely. Local hot spots need to be identified, the influence of these hot spots on the PFAS burden in the environment should be investigated, and environmental regulations should be implemented for these hot spots to reduce their environmental impact. Therefore, we recommend a more routine monitoring of PFAS, including new PFAS that are currently used as perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) alternatives, which are not regulated and environmentally concerning.
