绿色植物对室内空气污染的净化作用

The pathway and conversion mechanism, influencing factors, and physiological and molecular mechanism were also discussed. The different indoor ornamental plants showed different removal efficiencies of volatile organic compounds (VOCs), formaldehyde and BTEX (benzene, toluene, xylene and ethylbenzene). And the same plant had selective characteristic for removal of different indoor pollutants. Plants could uptake the VOCs, and decompose and transform pollutants or assimilate pollutants as carbon source through self- metabolism. However, metabolism related enzymes had different responses to different treatments. Signal transductions and metabolic pathway should be further investigated. The removal efficiencies were significantly affected by plant species, air compounds properties, stomata and cuticle compositions, leaf area, light conditions and photosynthetic types. There was no obviously positive correlation between plant removal capability and resistance to pollutants. Further studies are needed in the fi
