b.2) Domestic biomass pollution

The high costs and limited availability of electricity and fossil fuels in many developing countries lead to frequent domestic use of biomass fuels, including wood, manure, and agricultural waste. It is estimated that in developing countries, 30% of urban households and 90% of rural ones use biomass fuels as the major source of energy for cooking and heating (16).

These are usually burned under inefficient conditions and often without any type of chimney. Particulate levels in these homes are about 20 times greater than in developed countries (17).

Studies from Nepal (18), Gambia (19), Zimbabwe (20), South Africa (21), Argentina (22), and the United States (23, 24) have reported higher respiratory morbidity among young children exposed to indoor pollution. In the Nepalese study, the incidence of ARI, particularly the severe cases, was directly associated with the number of hours each infant spent near a stove. Native American children under 2 years of age who were exposed to wood-burning stoves were about 5 times more likely to have radiologically confirmed pneumonia than children of the same age and sex from homes without these stoves. Smoking was uncommon in both populations, but the possibility of confounding by other variables cannot be ruled out.
• 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!
