Phytoremediation is the use of plants for the in situ cleanup of contaminated soils, sediments, and ground water. Pot-scale experiment evaluated phytoremediation by Pteris vittata L. (Chinese brake fern) for mudstone containing arsenic (12.3 mg/kg-DW) of the Hakobuchi Group in the Yubari City, central Hokkaido, Japan. In this experiment, fronds of Pteris vittata L. were taken after 18 weeks growth in soil. The following properties became clear after examining the experimental results. (1) The brake fern can growth in the soil made from mudstone containing arsenic. (2) The highest arsenic concentrations in the frond of Pteris vittata L. growing in the soil are about 3000 mg/kg-DW. (3) The fern removed arsenic about 10 % from mudstone. The results suggested that the brake fern has a great poten tial to be used for phytoremediating soils with low concentration of arsenic.
