NASA Study Shows Common Hants Help Reduce Indoor Air Pollution
Common indoor plants may provide a valuable weapon in the fight against rising levels of indoor air pollution. Those plants in your office or home are not only decorative, but NASA scientists are finding them to be surprisingly useful in absorbing potentially harmful gases and cleaning the air inside modern buildings.
NASA and the Associated Landscape Contractors of America (ALCA) have announced the findings of a 2-year study that suggest a sophisticated pollution-absorbing device Links Of London Necklaces the common indoor plant may provide a natural way of helping combat “SICK BUILDING SYN¬DROME”.
Research into the use of biological processes as a means of solving environmental problems, both on Earth and in space habitats, has been carried out for many years by Dr. Bill Wolver-ton, formerly a senior research scientist at NASA’s John C. Stenos Space Center, Bay St. Louis, Miss.
Based on preliminary evaluations of the use of common indoor plants for indoor air purification and revitalization, ALCA joined NASA to fund a study using about a dozen popular varieties of ornamental plants to determine their effectiveness in removing several key pollutants associated with indoor air pollution. NASA research on indoor plants has found that living plants are so efficient at absorbing contaminants in the air that some will be launched onto space as part of the biological life support system aboard future orbiting space stations.
While more research is needed, Walkerton says the study has shown that common indoor landscaping plants can remove certain pollutants from the indoor environment. “We feel that future results will provide an even stronger argument that common indoor landscaping plants can be a very effective part of a system used to provide pollution free homes and work places,” he concludes.
Each plant type was placed in sealed, Plexiglas chambers in which chemicals were injected. Philodendron, spider plant and the golden photos were labeled the most effective in removing formaldehyde molecules. ^Flowering plants such as gerbera daisy Links Of London Rings and chrysanthemums were rated superior in removing benzene from the chamber atmosphere. “Plants take substances out of the air through the tiny openings in their leaves,” Wolver ton said. “But research in our laboratories has determined that plant leaves, roots and soil bacteria are all important in removing trace levels of toxic vapors. “
“Combining nature with technology can increase the effectiveness of plants in removing air pollutants,” he said. “A living air cleaner is created by combining activated carbon and a fan with a potted plant. The roots of the plant grow right in the carbon and slowly degrade the chemicals absorbed there,” Wolver ton explains.
NASA research has consistently shown that living, green and flowering plants can remove several toxic chemicals from the air in building interiors. You can use plants in your home or office to improve the quality of the air to make it a more pleasant place to live and work — where people feel better, perform better, and enjoy life more. NASA research on indoor plants has found that living plants are so efficient at absorbing contaminants in the air that some will be launched onto space as part of the biological life support system aboard future orbiting space stations.
