The Power of Plants

 

Damaging pollutants assault us every day. Where we live and where we work. Toxic chemicals used in manufacturing seep out of everything from carpeting, upholstery, foam insulation and pressed-wood products. It doesn't stop there, also included are cigarettes, permanent press clothes, paint, plastic, synthetic fibers, printing inks and dry-cleaning. But now plants are a proven way to reduce those levels of indoor pollutants in homes and offices, particularly in the sick buildings with permanently sealed windows.

A new study has found that about half of the carbon dioxide emitted by burning fossil fuels is absorbed by (exterior) plants in the Northern Hemisphere,

showing that plants play a role about equal to that of oceans, to which most of the absorption had previously been attributed.

An easy way to improve air quality is to add plants .Houseplants are especially effective at cleaning polluted air.

Study finds plants reduce indoor air pollution

 

According to a study by (NASA) the National Aeronautics and Space Administration common house and office plants can effectively remove the harmful pollutants from indoor air.

 

The results of this two-year study indicate that plants do provide a natural, cost-effective way to clean indoor air and fight the latest sick building syndrome.

Dr. Bill Wolverton, senior research scientist at NASA's John C. Stennis Space Center in Mississippi, conducted the study, Interior Landscape Plants for Indoor Air Pollution Abatement, Dr. Wolverton has studied plants and pollution treatment for 20 years.

The study concentrated on three of the most common indoor air pollutants: formaldehyde, benzene, and trichloroethylene. These and other common indoor air pollutants, such as asbestos, radon, lead and carbon monoxide, are often emitted from furnishings, office equipment and different types of building materials.

In the study, philodendron, spider plant and golden Pothos most effectively removed formaldehyde from the air. Gerber daisies and chrysanthemums best-removed benzene. Other plants that removed toxic chemicals from the air, included bamboo palm, peace lily, corn plant, mother-in-law tongue and English ivy. Virtually all tropical plants are potentially powerful air cleaners. All green plants produce oxygen and absorb carbon dioxide during photosynthesis.

People worry so much about outdoor air, but indoor air may be a far more serious problem, said Dr. Wolverton. This study demonstrates that plants are a natural solution to indoor air pollution not just in the future NASA spaces but in the offices and homes of today.

 

Dr. Wolverton has conducted follow-up research to the NASA study, which includes additional plants and indoor air pollutants. Sick-building syndrome is a result of indoor air pollution. As many as one in five workers may suffer from the condition. It can cause discomfort and serious illness, including, respiratory irritation, dizziness, headaches, skin rashes, nausea and vomiting. The Environmental Protection Agency (EPA) reports that indoor air pollution represents, a major portion of the public's exposure to air pollution, and estimates the cost at $1 billion dollars per year in sick leave, lost earnings and low productivity.

Plants are Natures

Most Efficient Environmental Air Cleaner!

 

The NASA study also proves that plants are not only beautifying our indoor environment, they make them healthier to live in .NASA studied the benefits of plants for use in future space stations and closed environments and concluded that properly designed interiorscaping can provide an inexpensive means of removing pollutants from the air in our offices and our homes.

Indoor air pollution comes from the various fibers (carpet, fabrics, wall coverings) and solvents (wallboard, paints varnishes, furniture) we use to build and decorate our homes and offices. It takes only two potted plants per 100 square feet of floor space to help clean and refresh the air in the average home or office.

Virtually every tropical plant and many flowering plants are powerful removers of indoor air pollutants. Below is a chart of the plants in the NASA study that most effectively removed pollutants from the air.
