Prelimilary Studies On The Effect Of Interior Plants Removing Formaldehyde

Indoor air quality is related to human's life. Everyday people spend most of their time in building. In face of the polluted chemistry gases produced by living environment, which bring worse influence on people's healthy of body and heart, people are in great need of improving indoor air quality to get better living environment.Now there are many ways of decreasing indoor air pollution. The studies not only provide a ecological measure related to life to remove indoor air pollution, but also bring beauty for people——using interior plants to decrease the concentration of formaldehyde indoor. Formaldehyde is a universal dangerous gas of indoor polluted air, which has a great influence on people's healthy.The primary conclusions are:1. We get the value of 13 kinds of potted plants absorbing Formaldehyde. We find that the value of experiment plants(mg) : Syngonium podophillum(1.450), Aglaonema crispum cv. Silver Queen(1.366), Dracaena cambodiana(1.342), Dracaena deremensis'Virens Compacta'( 1.299) , Schefflera octophylla (1.203), Pandanus veitchii (1.185), Dieffenbachia picta(1.153), Chlorophytum comosum (0.908), Scindapsus aureus (0.891), Spathiphyllum kochii (0.859), Aloe vera var.chinensis (0.856), Chamaedorea elegans (0.853), Sansevieria trifasciata'Laurentii'(0.797).2. Based on their high value, we find that the value order of experiment plants leaves(mg) : Pandanus veitchii ( 1.290 ) >Scindapsus aureus (1.257)> Syngonium podophillum (1.243 )>Dieffenbachia picta(1.225)>Spathiphyllum kochii(1.217)> Aglaonema crispum cv. Silver Queen(0.631)>Dracaena cambodiana(0.612)> Sansevieria trifasciata'Laurentii('0.579)>Chamaedorea elegans(0.531)>Aloe vera var.chinensis(0.504)>Chlorophytum comosum(0.494)> Schefflera...
