[Sound Effects: Healthy heart beating :02 and under]

A recent study by Harvard researchers revealed that air pollution may be responsible for up to three percent of hospital admissions for heart problems, including chest pains, heart attacks, and even death. The major villains, airborne particles called "PM₁₀," settle deeply into the lungs, and may interfere with the supply of oxygen to the heart. Produced by cars, power plants, and factories, these particles are so small they can't be seen under a microscope. Some critics suggest the EPA's standards for PM₁₀ may not be strict enough, but the agency will need to carefully weigh competing issues before adopting tighter standards. [:36]
