Sick Building Syndrome
People living or working in newer, well insulated buildings, have experienced a significant rise in these illnesses: allergies, asthma, eye, nose or throat irritations, fatigue, headaches, nervous-symptom disorders, respiratory problems, sinus congestion (Dr. B.C. Wolverton. How to Grow Fresh Air. Penguin Books, 1996.) In addition to the airtightness of the buildings, synthetic furnishings, human breathing, and poor ventilation systems contribute to the poor air quality.
Typical air pollutants in a "sick" building include formaldehyde gas, xylene/toulene gas, benzene, trichloroethylene, chloroform, ammonia, alcohols, and acetone. These are emitted into the air by products ranging from facial tissues to gas stoves. With our limited ventilation systems, is it any wonder that our eyes may burn in some buildings even if we can't specifically identify a cause?
Through studies by NASA, scientists have identified 50 houseplants that remove various gases/pollutants mentioned above. Wolverton rated these plants for removing chemical vapors, ease of growth, resistance to insect problems, and transpiration (the amount of water they expire into the air). Plants are necessary for helping to ad moisture to our too fdry buildings. These plants in order of effectiveness:
