Assessment of Phytoremediating Potential of Aglaonema commutatum Schott for Indoor Pollutants

Abstract

Indoor pollution is a major threat in today's world. Potential of Aglaonema commutatum Schott (Chinese evergreen) as a Phytoremediator, was tested against the gaseous pollutants released from household products like mosquito coil, joss (incense) sticks and naphthalene balls. The indoor pollutants released from these products are very dangerous to our health. These gases may affect our respiratory system, nervous system etc. Potted indoor plants were exposed to the pollutants. After exposing these plants to selected indoor pollutants, they were monitored with respect to visible symptoms, Pollution Indication Index (PII) and Gas Liquid Chromatography (GLC). The experiments were repeated thrice. Amongst all products tested, Aglaonema was found more tolerant to pollutants released from mosquito coil than other two products studied. It showed no visible injury after exposure, Pollution Indication Index was 0. After exposure, when plant extracts were analysed on Gas Liquid Chromatography (GLC) it showed many peaks of new compounds absorbed by the plant as compared to control. However, phytoremediation of Indoor pollutants using Aglaonema commutatum is still under research phase where understanding of which exact compounds are absorbed by the plant, how it translocates, and metabolizes is required.
