Particulate Air Pollution,Lung & Heart Disease,and Infection

PARTICULATE AIR POLLUTION, LUNG AND HEART DISEASE, AND INFECTION

Active and passive tobacco smoke, biomass-fuel smoke, and traffic-related air pollution have broad adverse health effects on the respiratory and cardiovascular system, as well as on cardiopulmonary mortality.2,4–7 Because the relation of these exposures with cardiovascular disease mortality is nonlinear, control efforts are particularly beneficial at lower levels of exposure. There is a strong argument for improving air quality early on in the combat against noncommunicable diseases.8

Furthermore, there is an interrelation among exposure to inhaled particles, noncommunicable diseases, and infections. Populations in economic transition often have had high exposure in utero and during childhood to smoke from biomass combustion (for cooking and heating). Early exposure to inhaled particles and fumes is associated with higher rates of acute, repeated, or chronic respiratory infections (for example, acute lower respiratory tract infections9 and tuberculosis [TB]10). Early childhood respiratory infections are in turn risk factors for chronic pulmonary diseases in adulthood.11 The lungs of people exposed in early life to indoor air pollution may become more susceptible to the adverse effects of smoking and traffic-related air pollution—for example, developing chronic obstructive lung disease (COPD) at an earlier age.

With rapid urbanization, many populations in low- and middle-income countries are going from high exposures to the products of biomass combustion in childhood to high adult exposures to traffic-related air pollution. Those moving into urban slums may experience a triple stress—facing the socioeconomic stress of poverty, the hazards of indoor air pollution from traditional cooking practices, and the hazards of outdoor air pollution from heavy traffic. Furthermore, social stress may amplify the adverse effects of air pollution.12 None of these hazards will be reduced with strategies (emphasized by the UN Summit) that focus on lifestyle.

• 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!
