The project aimed to determine particulate matter (PM) accumulation per leaf area of 10 Taiwan-native indoor plant species, and their ability to reduce dust evolution in simulation chamber. Results showed PM accumulation per leaf area ranged 7.1-263.3 μg•cm-2 for the 10 tested plant species, and with Phalaenopsis aphrodite being the highest, followed by Aspidistra elaitor, Asplenium nidus, Davallia mariesii, Adiantum capillus-veneris, Ficus pumila, Nageia nagi, Schefflera arboricola, and Pteris multifida. PM concentration decreased more rapidly when one 9-cm potted Phalaenopsis aphrodite, Asplenium nidus, Adiantum capillus-veneris, or Podocarpus costalis was placed within the chamber. Nine, 18, or 27 9-cm potted Taiwan-native indoor plant species were placed in several offices with similar volume (12.5 m2 × 2.3 m) for one week. Results showed formaldehyde and CO2 concentrations decreased after placing Asplenium nidus, Schefflera arboricola, Pteris multifida, Podocarpus costalis, or Ficus pumila. Ten potted Asplenium nidus, Davallia mariesii, Nageia nagi, Phalaenopsis, Kalanchoe, and Sinningia speciosa each were placed in social classroom (68.5 m2 × 2.6 m) and informative counter (21.6 m2 × 2.7 m) of an Agriculture Promotion and Education Station. Results showed CO2 and PM concentrations decreased after placing these plant species.
Sixteen conferences were held on May 30, June 18, 24, 28, July 7, 16, 30, Aug. 4, 20, 23, 27, Sept. 3, 29, Oct. 6, 13, and Nov 3 for promoting indoor and community greening. A total of 1316 people joined. Information related indoor and community greening were updated online.
New information for Handbook on Plants that Purify Community Air was collected and an alteration table was given. Plants of small gardens within EPA offices were constantly changed.
