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 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.
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. 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.
Offices and residential apartment buildings often connect directly to parking garages, either by doors or elevator shafts, making it difficult to avoid harmful gasoline-related compounds seeping into work and residential areas. Many buildings are also exposed to gasoline fumes from nearby roads and highways.
Breathing gasoline fumes can lead to lung irritation, headaches and nausea, and has been linked to an increased risk of cancer, asthma and other chronic diseases from longer term exposure, contributing to decreased life expectancy.
