It is estimated that about 2.4 billion people around the world, or about 40% of the world's population, depend on biomass fuels (wood, charcoal, dung, crop residue) to meet their energy needs for cooking and heating. The burden is especially high in Asia. Studies suggest that levels of pollutants including PM10 and PAHs indoors in homes where biomass fuels are used far exceed levels recommended as safe. While in vitro and in vivo studies in animal models suggest that wood smoke emission extracts are mutagenic and carcinogenic, epidemiologic studies have been inconsistent. In this review, we discuss possible carcinogenic mechanisms of action of biomass fuel emissions, summarize the biological evidence for carcinogenesis, and review the epidemiologic evidence in humans of biomass fuel emissions as a risk factor for lung cancer. Finally, we highlight some issues relevant for interpreting the epidemiologic evidence for the relationship between biomass fuel exposure and lung cancer: these include methodologic considerations and recognition of possible effect modification by genetic susceptibility, smoking status, age of exposure and histologic type.

• The Surgeon General has determined that there is no safe level of exposure to ambient smoke!

• If you smell even a subtle odor of smoke, you are being exposed to poisonous and carcinogenic chemical compounds!

• Even a brief exposure to smoke raises blood pressure, (no matter what your state of health) and can cause blood clotting, stroke, or heart attack in vulnerable people. Even children experience elevated blood pressure when exposed to smoke!

• Since smoke drastically weakens the lungs' immune system, avoiding smoke is one of the best ways to prevent colds, flu, bronchitis, or risk of an even more serious respiratory illness, such as pneumonia or tuberculosis!
Does your child have the flu? Chances are they have been exposed to ambient smoke!
