This study was performed to select the effective plant for phytoremediation of heavy metal contaminated areas. After cultivation of twelve Pteridophyta species on soil contaminated with heavy metals for 8 weeks, the growth response and accumulation ability of each parts for heavy metal, such as arsenic(As), cadmium(Cd), copper(Cu), lead(Pb), and zinc(Zn) were analyzed. Except Adiantum capillus-veneris, growth of eleven Pteridophyta species were relatively fine. Arsenic accumulation ability was the highest by Pteris multifida(66.9 mgㆍkg⁻¹ DW) and P. vitata(62.2 mgㆍkg⁻¹ DW) in aerial part, and P. vitata(13.6 mgㆍkg⁻¹ DW) in underground part. On the other hand, cadmium accumulation ability was low in all the twelve species of Pteridophyta. The underground part of P. ensiformis showed the highest copper accumulation(44.4 mgㆍkg⁻¹ DW) and in case of aerial part, Adiantum capillus-veneris(26.8 mgㆍkg⁻¹ DW) was highest in copper content. In lead, 1.2(Athyrium yokoscens) ~ 8.8 mgㆍkg⁻¹ DW(Pteris multifida) were accumulated in aerial part among twelve Pteridophyta species and 1.2(Pteris ensiformis) ~ 10.3 mgㆍkg⁻¹ DW(P. dispar) in the underground part. The aerial part of Thelypteris viridifrons showed the highest zinc accumulation(96.8 mgㆍkg⁻¹ DW) and in case of underground part, Pteris multifida(63.6 mgㆍkg⁻¹ DW) showed the highest ability.
