Plant responses to elevated CO2

Formaldehyde removal capacity of Spathiphyllum wallisii Regel was assessed to know the indoor air quality. The gaseous formaldehyde of about 5 ppm was released into the static chamber of volume 1 m 3. Test plant used was Spathiphyllum wallisii, a house plant surviving in low light. The indoor plant was chosen based on its growth in the medium. Medium was inoculated with Sphingomonas consortium, which helps the process of phytoremediation. Activated charcoal was also added in the medium, to increase the absorptive surface. The exposure given was for 24 hours. Experiment was replicated for five times. Air quality in the chamber was monitored on advanced formaldehyde detector, at the start of the experiment and after 24 hours. Leaves of the plants were analysed by DNPH using LCMS method for quantification of formaldehyde. Quantification of formaldehyde from leaves ranged between 0.09-1.006 ppm. Formaldehyde detector showed reduction in formaldehyde quantity from 4.998 to 0 ppm in 24 hours. This clearly indicates that Spathiphyllum wallisii can be used as a phytoremediator for indoor air quality, especially for formaldehyde absorption.
