Aqi range

What is AQI level mean? When the AQI is in this range. The AQI is between and 100. People who are unusually sensitive to ozone or particle pollution may experience respiratory symptoms. Unhealthy for Sensitive Groups.

The daily of the index are used to convey to the public an estimate of air pollution level. AQI refers to the Air Quality Index. An AQI of 1is equivalent to the National Ambient Air Quality Standard (NAAQS).

An AQI greater than 1is considered to be above the national standard or NAAQS. AQI values at and below 1are generally considered to be satisfactory. Daily Air Quality Standard. The World Air Quality Index project has exercised all reasonable skill and care in compiling the contents of this information and under no circumstances will the World Air Quality Index project team or its agents be liable in contract, tort or otherwise for any loss, injury or damage arising directly or indirectly from the supply of this data. People are no longer exposed to any health risk because the quality of air is pure.

Be highly active outside and spend more time. The ozone AQI between 1and 3is computed by selecting the larger of the AQI calculated with a 1-hour ozone value and the AQI computed with the 8-hour ozone value. Emergency conditions: everyone avoid outdoor physical activity. Levels above 3rarely occur in the United States.

AQI Look-up Table for Ozone concentrations Hazardous is 3to 500. The entire population is more likely to experience serious health effects and should avoid all outdoor exertion. Temperatures will also be a bit on the warm side coming in about 3-degrees above the average of again this afternoon (yesterday we topped out at 96).

As the disturbance shifts eastward today, a strong ridge of high pressure will quickly build into the region resulting in clear skies, warm temperatures, and light winds. Respiratory symptoms possible in unusually sensitive individuals, possible aggravation of heart or lung disease in people with cardiopulmonary disease and older adults. 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 example, if the PM2. AQI is 12 the PMAQI is 5 SOis 3 NOx is 5 and all other pollutants are less than 12 then the AQI is 125–determined ONLY by the concentration of PM2. Each category corresponds to a different level of health concern.

The air quality index ( AQI ) is an index for reporting daily and hourly air quality. Air quality and pollen information for over 1countries in the world. It is an indication of how clean or polluted the air is in areas across NSW. The highest AQI value and associated average (1-hour, 8-hour, or 24-hour) that is responsible for the AQI rating are highlighted bold in the table. PM-is measured at standard pressure and temperature conditions.

Aggravation of pre-existing heart and lung disease symptoms are likely. Although general public is not likely to be affected at this AQI range , people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air. AQI will only submit data to CMS for individual quality reporting for providers who have signed consent forms. Others are not likely to be affected when the AQI is in this range.

Poor Sensitive groups should reduce or reschedule strenuous outdoor activities. Other adults are not likely to be affected when the AQI is in this range. Simply search for OregonAir in your app store. Several reports are available and range from a quick snapshot of air quality, to more detailed customized reports for selected dates.

Real-time monitoring sites appear color coded according to current measurements and AQI calculations.
