Poly- and per-fluoroalkyl substances (PFAS) in the African environments: progress, challenges, and future perspectives.

Per- or poly-fluoroalkyl substances (PFAS) are a group of anthropogenic compounds that are used in a variety of industrial processes and consumer products with their ubiquitous presence in the environment recently gaining relevant attention. Progress and milestones on PFAS contamination within multiple environments from African continent are highlighted in this review. Identification and quantitation of PFAS within African environments is important to the public at large because of their toxicity and possible ecotoxicological risk.
