Abstract :
The experiments were carried out indoors to observe and analyze the variations of urease, catalase, and phosphatase activities in soil samples with presence of PFOA. The results showed that during the incubation period, the urease activity could be significantly inhibited over a selected range of PFOA concentrations. As for the catalase and the phosphatase activities, they were first stimulated and then decreased with increasing PFOA concentration.
