This study was conducted to evaluate the effect of soil amendments on changes in enzyme activity in soils polluted with As. The effects of S and calcium superphosphate (CSP) on the activities of dehydrogenase, urease, arylsulfatase (ASF), β-glucosidase, and phosphatase (PHA) were measured in paddy soils. In CSP-amended soil, As concentration in soil solution was lowest and rice growth increased. However, the activity of PHA was significantly lower for CSP-amended soil (0.9 - 1.4 μmol h<SUP>-1</SUP> g<SUP>-1</SUP>) than control and S-amended soils (2.3 - 2.7 μmol h<SUP>-1</SUP> g<SUP>-1</SUP>). As availability was reduced in CSP- and S-amended soils, and in those soils, the activities of ASF were approximately two times higher (2.4 - 3.9 μmol h<SUP>-1</SUP> g<SUP>-1</SUP>) than that in control (1.3 - 2.0 μmol h<SUP>-1</SUP> g<SUP>-1</SUP>). Overall, ASF activity could be used as an index for evaluating changes in quality of As-polluted paddy soils after amendment treatment.
