| Abstract: | To evaluate the influence of various Cr(VI) concentrations (0.05, 0.25, 0.50, 1.00 and 2.00 g/kg) on the activity of soil
enzymes, the activities of catalase, polyphenol oxidase, dehydrogenase, alkaline phosphatase in soils were investigated in
the incubation experiment with a period of 35 d. The results indicate that all the tested Cr(VI) concentrations significantly
inhibit dehydrogenase activity by over 70% after 35 d. The activity of alkaline phosphatase is slightly inhibited during the
whole experiment except for on the day 7. Cr(VI) has no obvious effect on the activity of catalase in soil. On the contrary,
Cr(VI) stimulates the activity of polyphenol oxidase. The results suggest that dehydrogenase activity can be used as an indicator
for assessing the severity of chromium pollution.
