- Abstract
Soil and groundwater are important sites for the storage and transport of perfluorooctane sulfonic acid (PFOS), as well as areas for the presence and movement of bacteria. Bacteria are usually present as biofilms on the surface of media. It is reported that bacteria can also adsorb PFOS, so the direct contact between bacteria/biofilms and PFOS may affect the transport of PFOS. To investigate the effect of biofilm on PFOS transport, Gram-negative Pseudomonas aeruginosa was selected as the representative strain to construct indoor column experiments to investigate the effect of biofilm on PFOS transport in saturated quartz sand under different background solutions. The results showed that the presence of biofilm can enhance the retardation of PFOS transport in quartz sand. When the background solution was CaCl2, the retardation of PFOS was more significant than that of NaCl with the same ionic strength. This study is helpful to better understand the effect of biofilm on the transport of PFOS, and provides a new idea for evaluating the transport characteristics of PFOS in underground environment.
