300 | Current Ozone (O<sub>3</sub>) and Particulate Matter (PM<sub>2.5</sub>) data are published as soon as practical after the end of each hour and as such are not fully validated. Maps are also archived in the same way. Therefore, data are only approved for the expressed purpose of reporting and forecasting the Air Quality. Maps are generally available after 9 a.m. EST. The animated Particle map is for a 24-hour loop. Each color-coded circle on the maps above indicates the Air Quality Index (AQI) category for a ground-based air quality monitoring station. See the AIRNow Web site for information on how AQI maps are calculated and about monitoring stations.</p> |

---|
310 | </p> |
---|
311 | <p>The AQI is an index for reporting daily air quality. It tells you how clean or polluted your air is, and what associated health effects might be a concern for you. The AQI focuses on health effects you may experience within a few hours or days after breathing polluted air. EPA calculates the AQI for five major air pollutants regulated by the Clean Air Act: ground-level ozone, particle pollution (also known as particulate matter), carbon monoxide, sulfur dioxide, and nitrogen dioxide. For each of these pollutants, EPA has established national air quality standards to protect public health. Ground-level ozone and airborne particles are the two pollutants that pose the greatest threat to human health in this country.</p> |
---|
312 | |
---|
313 | <p class="Bold">How Does the AQI Work?</p> |
---|
314 | <p>Think of the AQI as a yardstick that runs from 0 to 500. The higher the AQI value, the greater the level of air pollution and the greater the health concern. For example, an AQI value of 50 represents good air quality with little potential to affect public health, while an AQI value over 300 represents hazardous air quality.</p> |
---|
315 | |
---|
316 | <p>An AQI value of 100 generally corresponds to the national air quality standard for the pollutant, which is the level EPA has set to protect public health. AQI values below 100 are generally thought of as satisfactory. When AQI values are above 100, air quality is considered to be unhealthy at first for certain sensitive groups of people, then for everyone as AQI values get higher.</p> |
---|
317 | |
---|
318 | <p class="Bold">Understanding the AQI</p> |
---|
319 | <p>The purpose of the AQI is to help you understand what local air quality means to your health. To make it easier to understand, the AQI is divided into six categories:</p> |
