Air quality index pollutants

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. EPA sets national air quality standards for six common air pollutants. Each year EPA tracks the levels of these air pollutants in the air. EPA posts the of our analyses to this web site.

The GAIA air quality monitoring stations are using high-tech laser particle sensors to measure in real-time PM2. Very easy to set up, they only require a WIFI access point and a USB power supply. Once connecte air pollution levels are reported instantaneously and in real-time on our. Get real-time, historical and forecast PM2. Read the air pollution in Pattaya, Thailand with AirVisual.

EPA and local officials use the AQI to provide simple information about your local air quality , how unhealthy air may affect you, and how you can protect your health. 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. Keep track of the most polluted cities in the world with our air quality index (AQI) ranking. For each of these pollutants , EPA has established national air quality standards to protect public health. Air quality and pollution.

It transforms complex air quality data of various pollutants into a single number and colour. AQI has six categories of air. This site provides air quality data collected at outdoor monitors across the United States, Puerto Rico, and the U. Users can downloa output, view or visualize the data. Air Quality Index (AQI) is a tool to showcase air quality status. When the AQI level ( air quality index ) is below 5 people are breathing fresh, clean air.

People are no longer exposed to any health risk because the quality of air is pure. Be highly active outside and spend more time. Breathe as much fresh air as you can. Concentrations values for up to five key pollutants determine the index level that reflects air quality at each monitoring station.

The index corresponds to the poorest level for any of five pollutants , according to the table shown below. Circles on the map represent the locations of air quality monitoring stations. These six pollutants are carbon monoxide, lea nitrogen oxides, ground-level ozone, particle pollution (often referred to as particulate matter), and sulfur oxides. Although AQI includes all available pollutant measurements, you should be aware that many areas have monitoring stations for some, but not all, of the pollutants. A value in the unhealthy range, above the national air quality standard for any pollutant, is of concern first for sensitive groups, then for everyone as the AQI value increases.

The Technical Services Program of the Air Pollution Control Division is responsible for the collection and analysis of air quality data throughout the state. The program is also responsible for providing modeling analyses to determine the impacts various sources will have on air quality. The following spreadsheets provide air quality status and trends for counties and cities, defined as CBSAs (Core-Based Statistical Areas Exit), with monitoring data.

Current air pollution levels for fine particles and ozone, along with a five-day forecast.
