디벤바키아, 벤자민고무나무, 그리고 아레카야자를 이용하여 화분의 지피물질에 따른 포름알데히드 제거 효율을 측정하였다. 화분 지피물질로는 가는 자갈, 모래, 수태, 셀라지넬라를 이용하였다. 셀라지넬라 지피가 포름알데히드 제거 효율이 가장 높았고, 모래지피가 가장 낮았다. 가스 처리 2시간 후 셀라지넬라 지피의 포름알데히드 제거율은 모래에 비해 25% 높게 나타났다. 지피 방법과는 상관없이 식물 종류별로 포름알데히드 제거율을 비교하면 디벤바키아가 가장 우수하였고 그 다음이 벤자민고무나무, 아레카야자 순이었다. 지피 방법별 초기 가스 농도의 절반에 도달하는 T<SUB>5</SUB>0%은 자갈, 모래, 수태 그리고 셀라지넬라가 각각 88, 118, 81, 53(분)이었다. 이러한 결과는 지피물질에 따라 오염된 공기가 근권부에 도달하는 양이 다르기 때문으로 보인다. 결과적으로 지피물질별 포름알데히드 제거 효율은 셀라지넬라가 가장 우수하였다.

The efficiency of formaldehyde removal by the ground cover materials of potted plants was assessed in Dieffenbachia amoena, Ficus benjamina, and Chrysalidocarpus lutescens. These potted plants were covered with fine gravel, sand, unplanted sphagnum moss, and planted Selaginella tamariscina. The removal capacity of potted plants covered with materials was determined by formaldehyde (2 μL·L-1) in airtight chambers (1.0 ㎥) constructed of inert materials. The rate of formaldehyde removal by potted plants covered with S. tamariscina was the greatest and whereas, it’s removal by sand was the smallest. The rate of formaldehyde removal by potted plants with S. tamariscina increased about 26% as compared that with sand 2 h after gas exposure. In tested species, the amount of formaldehyde removal by potted D. amoena was the greatest plants irrespective of the ground cover materials of potted plants and followed by F. benjamina, and C. lutescens. To compare the removal efficiency between ground cover materials of potted plants, the time interval required to reach 50% of the initial concentration (T50%) was determined; fine gravel, sand, sphagnum moss, and planted S. tamariscina accounted for 88, 118, 81, and 53 min respectively. These results might be due to being different in contact with indoor air pollutants on ground of potted plants. Formaldehyde removal by potted plants was relevant to rhizosphere microorganisms. As a result, the efficiency of formaldehyde removal by potted plants covered with S. tamariscina was the greatest.
