    4   <TEXT>  Fine particulate matter (PM^2.5^) is defined as particles with a diameter smaller than 2.5 micrometers (um, or microns). PM^2.5^ can get deep inside the lungs and cause a variety of symptoms, such as painful breathing, chest tightness, headache, and coughing. PM^2.5^ can exacerbate respiratory infections, trigger asthma attacks and symptoms, and cause temporary reductions in lung capacity. Respiratory symptoms are more likely to occur when PM^2.5^ levels exceed the EPA's standard, but are possible when PM^2.5^ levels are below the standard, especially in sensitive populations. PM^2.5^ has been found in some studies to be associated with an increased risk of chronic lung disease^1^. The EPA recommends an annual PM2.5 standard of less than 12 micrograms per cubic meter. </TEXT>

Because of its small size, PM2.5 is able to get deep inside the lungs and cause a variety of symptoms, such as painful breathing, chest tightness, headache, and coughing.

    66  <TEXT> In addition to these adverse outcomes, PM^2.5^ can influence the environment in ways that will eventually affect human health. Fine particles cause haze which reduces visibility. The long-term effects of PM^2.5^, which settles in the soil, natural water sources, forests, and agricultural areas, are still to be determined. </TEXT>
