air quality index. A report of daily outdoor air quality conditions. In Minnesota and Utah, four pollutants are used to calculate the AQI: ground-level ozone, sulfur dioxide, carbon monoxide and fine particles PM2.5 .
Air Quality Index. The measurement of air quality that is calculated from ozone and fine particle pollution measurements over the past few hours. A higher AQI indicates a higher level of air pollution, and consequently, a greater potential for health problems.
Air Quality Index. The AQI is a scale of 0 to 500, developed by the U.S. Environmental Protection Agency and divided into several color-coded categories. The AQI scale serves as a simple tool for reporting the air quality of a particular region. A value of 101 or greater means that concentrations that violate national health-based standards for the pollutant in question (ground-level ozone or particle pollution) are either present or forecasted to be present.
The Air Quality Index is a tool that provides the public with clear and timely information on local air quality and whether air pollution levels pose a health concern.
Air Quality Index. an index for reporting how clean or dirty the local air is and what health effects people should be concerned with. The AQI focuses on health effects that occur within a few hours or days after exposure to polluted air. The AQI is used for five major air pollutants regulated by the Clean Air Act. These are ground-level ozone, particulate matter, carbon monoxide, sulfur dioxide, and nitrogen oxides. For each of these pollutants, EPA has established national air quality standards to protect against harmful health effects.
Air Quality Index – Tells you how clean the air is and whether it will affect your health.
Air Quality Index. A scale developed by the government to measure how much air pollution is in the air. The AQI measures five criteria pollutants -- ozone, particulate matter, carbon monoxide, sulfur dioxide, and nitrogen dioxide. AQI levels range from 0 (Good air quality) to 500 (Hazardous air quality). The higher the index, the higher the level of pollutants and the greater the likelihood of health effects. The AQI also has another category -- unhealthy for sensitive groups -- that ranges from 101 to 150. The AQI is usually used in weather reports. When it is high, there are warnings for people not to do things like sports or hard work outside. People with asthma or other lung problems are urged to stay inside on days that the AQI is high.
Air Quality Index. A guide that provides information about air quality and the health effects that might be a concern for the public.
Air Quality Index. Provides information on the adverse effects of the more common air pollutants. It is designed to identify the worst effects that may result from the mixture of pollutants currently being measured and to describe the prevailing air quality.
