Houseplants and indoor pollution

Researchers at the University of Georgia tested a number of common
houseplants for their ability to remove organic volatiles from indoor
environments. The indoor pollutants included benzene, toluene, octane,
tricholoroethylene (TCE), and alphapinene. Houseplants were rated as
superior, intermediate, or poor to reflect their ability to remove all
volatiles. None of the plants appeared to have been damaged by the
volatiles.
