The efficiency of volatile formaldehyde removal was assessed in 86 species plants representing five general classes (ferns, woody foliage plants, herbaceous Korean native and herbs). Phytoremediation potential by exposing the to gaseous (2.0 μL·L −1 ) airtight chambers (1.0 m 3 constructed inert materials measuring rate removal. Osmunda japonica , Selaginella tamariscina Davallia mariesii Polypodium formosanum Psidium guajava Lavandula spp., Pteris dispar multifida Pelargonium spp. were most effective tested, removing more than 1.87 μg·m −3 ·cm −2 over 5 h. Ferns had highest tested with O. (i.e., 6.64 leaf area h). individual were: ferns— ; plants— Rhapis excels Zamia pumila Chlorophytum bichetii Dieffenbachia ‘Marianne’, Tillandsia cyanea Anthurium andraeanum Nandina domestica herbs— Rosmarinus officinalis . separated into three groups based on their efficiency: excellent (greater 1.2 per cm 2 h), intermediate (1.2 or less 0.6), poor (less 0.6). Species classified as are considered viable phytoremediation candidates for homes offices where is a concern.
