Aqi 25

Think of the AQI as a yardstick that runs from 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 represents good air quality with little potential to affect public health, while an AQI value over 3represents hazardous 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. AQI will only submit data to CMS for individual quality reporting for providers who have signed consent forms. For practices that submitted paper consent forms and received receipt confirmation from AQI , no further action is required. The air quality index is a piecewise linear function of the pollutant concentration.

At the boundary between AQI categories, there is a discontinuous jump of one AQI unit.

Based on several studies at both low and high pollution levels, the human health effects are believed to be. Forecast will be issued daily by noon (PST) A ! Localized wildfire smoke, blowing dust, or other air quality situations may differ with the forecast as it pertains to your local area. The DSM501A is a detector capable of measuring the presence of fine particles in suspension in the atmosphere according to PM2. The AQI is not routinely updated on weekends and during holiday periods.

PM1 temperature, humidity and noise data of your location, city and state. Besides PSI readings and PM2. For example, Singapore’s AQI was 1at 6pm on Friday, which is classified as “unhealthy” by the website, a non-profit enterprise with support from a range of government agencies worldwide.

Air Quality Index Report. It reflects the air pollutant with the highest reading in the monitoring network. The map below provides information for each monitoring site in the network. Clicking on a specific site will take you to a new window where you can access current day and five-day hourly AQI.

AirNow for recent days that are not available from AQS. AQS data, as it becomes available, replaces any AirNow data. The critical pollutant is the pollutant with the highest AQI rating measured in the area.

The big particles are between 2. These particles cause less severe health effects. Respiratory symptoms possible in unusually sensitive individuals, possible aggravation of heart or lung disease in people with cardiopulmonary disease and older adults. Health Effects Statement PM2. Unusually sensitive people should consider limiting prolonged outdoor exertion.
