研究了气溶胶介导的全氟辛酸（PFO）从水体向大气的迁移以及随后的气相全氟辛酸（PFOA）排放。评估了这一过程促进全氟辛酸/全氟辛烷磺酸远距离迁移的潜力。在实验室实验中，从掺有PFO的去离子淡水和海洋沃茨中产生并收集气溶胶，并通过LC-MS/MS气体进行分析。还从系统中收集相样品并分析PFOA。气溶胶中的PFO浓度明显高于母体水体（
Aerosol-mediated transport of perfluorooctanoate (PFO) from a water body to the atmosphere and the subsequent emission of gas-phase perfluorooctanoic acid (PFOA) was investigated. The potential for this process to facilitate long-range transport of PFOA/PFO was assessed. In a laboratory experiment aerosols, were generated and collected from deionized fresh and ocean waters spiked with PFO and analyzed by LC-MS/MS Gas. phase samples were also collected from the system and analyzed for PFOA. Aerosols were found to have significantly higher concentrations of PFO than the parent water body (
