In a pot experiment, Pteris cretica 'Albo-lineata' ferns were cultivated and exposed to 20 and 100 mg As/kg soil for 6 months. Physiological and morphological changes of roots, as well as changes in soil quality of root zone and bulk soil were determined. The results showed that the accumulation of inorganic As did not significantly affect the yield of roots, but caused changes in root morphology and metabolism. Although the soil quality results varied according to the As dose, there was a clear difference between the root zone and the bulk soil. The activities of enzymes in the root zone were greater that those in the bulk soil. The results showed a significant effect of the high As dose, which decreased the activity of arylsulfatase, nitrate reductase, and urease in the root zone, while a decrease in acid phosphatase and nitrate reductase was observed in the bulk soil. The water-soluble As fractions, organic N, nitrate nitrogen and organic C were significantly affected by the high As dose.
