A ground-breaking study has revealed that plants can efficiently remove toxic gasoline fumes, including cancer causing compounds such as benzene, from indoor air.
The study was led by University of Technology Sydney (UTS) bioremediation researcher Associate Professor Fraser Torpy, in partnership with leading Australian plantscaping solutions company Ambius.
The researchers found that the Ambius small green wall, containing a mix of indoor plants, was highly effective at removing harmful, cancer-causing pollutants, with 97 per cent of the most toxic compounds removed from the surrounding air in just eight hours.
Poor indoor air quality is responsible for 6.7 million premature deaths globally, according to the World Health Organisation. Most people spend 90% of their time indoors at home, school or the workplace, so adopting new strategies to improve air quality is critical.
Ambius General Manager Johan Hodgson said the research presented new evidence into the critical role played by indoor plants and green walls in cleaning the air we breathe quickly and sustainably.
“We know that indoor air quality is often significantly more polluted than outdoor air, which in turn impacts mental and physical health. But the great news is this study has shown that something as simple as having plants indoors can make a huge difference,” Mr Hodgson said.
Previous studies on indoor plants have shown they can remove a broad range of indoor air contaminants, however this is the first study into the ability of plants to clean up gasoline vapors, which are one of the largest sources of toxic compounds in buildings worldwide.
