REDUCED productivity, bad moods and allergies
have all been linked to chemicals that float in the air at room temperature, or volatile organic compounds. In a new study, scientists have discovered that simply adding one medium-sized plant (of up to 50cm) to a medium-sized room (of about 4 x 5m) can increase interior air quality by up to 25 per cent. Commissioned by Hort Innovation and delivered by scientists at RMIT University and the University of Melbourne, the study involved a meta-analysis of more than 100 research papers from around the world.
University of Melbourne researcher Dominique Hes said the work was timely. “Human beings are less and less among nature with current estimates indicating that urban dwellers spend 90 per cent of their time in indoor environments – resulting in a high level of exposure to indoor contaminant compounds,” she said.
