Indoor Air Pollutants
Home Sick Home
How's the air at home? If you're like most people, your eyebrows raised and you find this to be an obscure question. But you might just want to take a little time to learn more about the air quality in your home. Besides, wouldn't you want to reduce the risk of allergic reactions, chronic bronchitis, nausea, headaches, fatigue and breathing problems, not to mention minimize the chance of slow or sudden toxic gas poisoning?
Visibly, your home may seem immaculate, but there are a number of sly culprits that contribute to indoor air pollution. And in newer, more energy efficient and airtight homes, pollutants are susceptible to becoming trapped inside the home.
According to the Chicago Tribune (May 14, 2000), 37 percent of homeowners have a carbon monoxide detector; one in eleven has a radon detector; and four in ten do not replace air filters every two to three months, as recommended.
What are some of the leading culprits that cause indoor air pollution?
- Heating systems that use gas or wood can emit carbon monoxide and nitrogen dioxide, which are both odorless and colorless. Carbon monoxide can be lethal if enough of it is ingested.
- Radon, the second leading cause of lung cancer next to cigarette smoking, is also an odorless and colorless gas that can seep into the home through cracks in basement floors, foundations and walls.
- Air conditioners, humidifiers and dehumidifiers, if not well maintained, can become a breeding ground for mold and mildew, which could cause allergic reactions.
Some of the recommendations from the U.S. Environmental Protection Agency and the American Lung Association include the following:
- Check for radon levels inside your home.
- Be sure that the flue is open when using your fireplace, and have the fireplace and chimney inspected annually for blockage or cracks.
- Install a carbon monoxide detector and ensure it works properly.
- >Check your home regularly for trapped moisture, find the cause and repair as soon as possible.
- Replace furnace filters regularly, every two to three months.
