| Abstract: |
| Perfluorooctanoic acid(PFOA) and perfluorooctanosulfonic acid(PFOS) are widely used in the production and application of a variety of industrial and household products. Owing to special properties such as thermal stability, chemical stability, and environmental persistence, they have been widely detected worldwide. At present, some progress has been made in research on the behavior of PFOA and PFOS in environmental media. This study summarized the progress of research on transport behavior of PFOA and PFOS in environmental media and related mathematical models. The mechanisms(electrostatic interactions, hydrophobic interactions, ligand exchange, and hydrogen bonding) and factors(organic matter content, mineral type, mineral content, medium moisture content, ion type, ionic strength, and pH) that affect the transport of PFOA and PFOS in environmental media, and mathematical models(convective-dispersive model, twosite model, two-region model, continuous-distribution multi-rate model, multiprocess rate-limited mass-transfer model, and TOSD transport model) are discussed and summarized. This will provide a comprehensive reference basis for further scientific research. |
