The efficiency of using 7 indoor plants, which were Chrysalidocarpus lutescens, Ficus robusta, Sansevienria trifasciata, Rhapis excelsa, Scindapusus aureus, Anthurium andraeanum and Pachira aquatica, for B·T·E (Benzene, Toluene, Ethylbenzene) removal were assessed at 1200 Lux light intensity in airtight chambers (1.27 m3). Rhapis excelsa, Chrysalidocarpus lutescens and Ficus robusta were among the most effective plants, completely removing for B·T·E within 38 hours, wherease Scindapusus aureus and Sansevienria trifasciata were the lowest in terms of removal efficiency. But when the removal efficiency was measured per unit leaf area (μg·m−3·−2), it was found that Scindapusus aureus, Anthurium andraeanum and Sansevienria trifasciata removed higher amount than Rhapis excelsa, Chrysalidocarpus lutescens and Ficus robusta. Plants with wide leaves and a big leaf area including Rhapis excelsa and Chrysalidocarpus lutescens showed higher removal efficiencies of B·T·E than those with smaller leaves such as Scindapusus aureus. Among the plants tested over 120 hours, the species that emitted the highest levels of CO2, involved with photosynthesis and respiration in plants, Pachira aquatica (11,560 ppm) was emitting 10 times more CO2 than Scindapusus aureus (1,260 ppm).
