EPA posts the of our analyses to this web site. Average particulate air pollution levels in many developing cities can be 4-times higher than WHO air quality guideline levels ,. Today, pollution levels in many areas of the United States exceed national air quality standards for at least one of the six common pollutants: Although levels of particle pollution and ground-level ozone pollution are substantially lower. For unhealthy peak levels of sulfur dioxide and nitrogen.

An air quality index (AQI) is used by government agencies to communicate to the public how polluted the air currently is or how polluted it is forecast to become. Public health risks increase as the AQI rises. Different countries have their own air quality indices, corresponding to different national air quality standards.

If a more accurate or continuous ozone evaluation is require a chemiluminescent monitor that is specific for ozone and can measure in the range of 0. It is a health protection tool used to make decisions to reduce short-term exposure to air pollution by adjusting activity levels during increased levels of air pollution.
