Removal of Volatile Organic Compounds by Means of a Felt-Based Living Wall Using Different Plant Species

Poor indoor quality affects people’s health and well-being. Phytoremediation is one way in which this problem can be tackled, with living walls being a viable option for places limited space. The aim of study was to evaluate the efficiency five plant species wall remove Volatile Organic Compounds (VOCs) identify whether type pollutant has any influence. An enclosed chamber used add contaminants n-hexane formaldehyde independently. Total VOCs were measured three days two scenarios: (1) empty chamber, (2) wall. Five prepared, each plants same species: Spathiphyllum wallisii, Philodendron hederaceum, Ficus pumila, Tradescantia pallida, Chlorophytum comosum. There no correlation between leaf area/fresh weight/dry weight contaminant reduction. In general, all more efficient reducing TVOCs when exposed than n-hexane. comosum most concentration both contaminants, wallisii least by far.
