Carbon Monoxide

Carbon monoxide is a colorless and odorless gas that results from the burning of fossil fuels. It can be emitted from cigarettes, automobiles and defective heating devices including furnaces. This is an acutely toxic gas and exposure can cause nausea, unconsciousness and even death.

Because you can neither see nor smell carbon monoxide, it is critical that you have detectors in your home. It is also highly recommended that you have your furnace cleaned and inspected on a regular basis.

Biological Sources

This is a broad category and the health effects are wide-ranging. Pollution caused by biological sources can irritate eyes, nose and throat, cause breathing problems, cause fevers and you can get a number of diseases from them.

Unfortunately, there is no way to totally eliminate the biological sources that cause pollution in your home, you can only hope to contain them.

Biological sources that can lead to pollution include mold and mildew, pets and insects. One way to reduce mold is by ensuring you have exhaust fans and ventilators. By making sure you vacuum and dust regularly, you keep dust mites to a minimum.

Volatile Organic Compounds (VOCs)

VOCs are toxic gases that are emitted from certain liquids and solids. These can be found in a very long list of household products including cleaning products, paints, varnishes, glues, building materials and paint removers. VOCs have both short-term and long-term effects. Some problems you might encounter when exposed to VOCs include headaches, nausea, dizziness and even cancer.


Radon is a highly radioactive gas that can get into your home through the ground. What makes radon so dangerous is that it is odorless, colorless and tasteless. Basically, you have to have your home tested to discover if you have it. In addition, it produces no immediate symptoms, which means you won’t even know if you are inhaling it.

Radon has been linked to lung cancer and causes as many as 30,000 deaths a year. Fortunately, radon testing is inexpensive and easy to do.

Nitrogen Dioxide

Nitrogen dioxide comes from many of the same sources as carbon monoxide and it also carries many of the same health risks. Fortunately, nitrogen dioxide has a sharp and easily detectable odor and it is reddish-brown in color.

Respirable Particles

Respirable particles are, simply put, small bits of matter floating around the air that can be easily inhaled. In addition to tobacco smoke, kerosene heaters, fireplaces and wood stoves are causes of respirable particles. Like other indoor pollutants, these particles can cause irritations in the eyes, nose and throat and other ailments.
