The findings by Wolverton’s research is that plants have the ability to breakdown these poisonous compounds.  For example, in a study done by the U.S. Environmental Protection Agency an 800 cubic foot room (10'x 10'x 8') contained pollution levels of approx. 1808 micrograms of Formaldehyde, 112 micrograms of Xylene and 67 micrograms of Benzene.  A single Boston fern can remove 1800 micrograms of Formaldehyde in about an hour.

Over the last few years, the U.S. E.PA., has rated indoor air pollution among the top four environmental health risks.

Plants placed within our personal breathing zone can add humidity (helpful for asthma sufferers), remove bieffluents and chemical toxins whilst suppressing airborne microbes.  The recommendation is two plants per each 100 sq feet of interior space, with groupings of several encouraged.

Whilst it is not envisaged that our offices and homes are transformed into a jungle, it is reassuring to know that the humble plant is perhaps our most silent health partner.
