Air quality is measured with the Air Quality Index, or AQI. The AQI works like a thermometer that runs from 0 to 500 degrees. However, instead of showing changes in the temperature, the AQI is a way of showing changes in the amount of pollution in the air. Air quality is a measure of how clean or polluted the air is. About National Air Quality Index It is determined on the basis of concentration of 8 pollutants, including Particulate Matter (PM 2. 5, PM 10), sulphur dioxide (SO2), nitrogen dioxide (NO2), carbon monoxide (CO), ozone (O3), ammonia (NH3) and lead (Pb). The index is based on the concentrations of five pollutants. The index is calculated from the concentrations of the following pollutants: Ozone, Nitrogen Dioxide, Sulphur Dioxide, PM2. 5 (particles with an aerodynamic diameter less than 2. 5 μm) and PM10. The air quality meter PCE-RCM 05 is used to continuously measure the particulate matter content at the workplace. The air quality meter displays PM2. 5 particulate matter as well as temperature and humidity on the display.

An instrument that measures air pressure is called a barometer. One of the first barometers was developed in the 1600s. The original instrument had mercury in the small basin, with an upside down glass tube placed in the mercury. As air pressure increased, the pressure would force more mercury in the tube.

Health Effects from Specific Pollutants Aggravated respiratory disease such as emphysema, bronchitis and asthma. Lung damage, even after symptoms such as coughing or a sore throat disappear. Wheezing, chest pain, dry throat, headache or nausea. Reduced resistance to infections. Increased fatigue.

Top 10 Most Ozone-Polluted Cities Los Angeles-Long Beach, Calif. Visalia, Calif. Bakersfield, Calif. Fresno-Madera-Hanford, Calif. Sacramento-Roseville, Calif. San Diego-Chula Vista-Carlsbad, Calif. Phoenix-Mesa, Ariz. San Jose-San Francisco-Oakland, Calif.

10 Tips to Protect Yourself from Unhealthy Air Check daily air pollution forecasts in your area. Avoid exercising outdoors when pollution levels are high. Always avoid exercising near high-traffic areas. Use less energy in your home. Encourage your child's school to reduce exposure to school bus emissions. Walk, bike or carpool. Don't burn wood or trash.

To test the air quality in your home, purchase an air quality monitor to check the levels of dust, allergens, chemical pollutants, and humidity in your home. Additionally, install carbon monoxide detectors on every floor to alert you to high levels of carbon monoxide.

These six pollutants are carbon monoxide, lead, nitrogen oxides, ground-level ozone, particle pollution (often referred to as particulate matter), and sulfur oxides.

Unhealthy air can also aggravate asthma and other chronic lung diseases. But polluted air can hurt more than the lungs! High levels of PM can increase the risk of cardiovascular disease, and lead to chest pain, palpitations, and fatigue.

Air Quality Scale AQI Air Pollution Level Health Implications 201-300 Very Unhealthy Health warnings of emergency conditions. The entire population is more likely to be affected. 300+ Hazardous Health alert: everyone may experience more serious health effects

The six levels of health concern and what they mean are: "Good" AQI is 0 to 50. Air quality is considered satisfactory, and air pollution poses little or no risk. "Moderate" AQI is 51 to 100.

Air quality measurement are commonly reported in terms of: micrograms per cubic meter (µg/m3) parts per million (ppm) or parts per billion (ppb)

The common air pollutants are: Particulate matter (PM10 and PM2. Ozone (O3) Nitrogen dioxide (NO2) Carbon monoxide (CO) Sulphur dioxide (SO2)

Here are 7 things you can do right away to improve the air quality in your home: Change Your AC Filter. Don't Forget About Other Air Filters. Check Your Air Ducts. Use Cooking Vents. Keep Your Rugs and Carpets Clean. Control Humidity in Your Home. Buy Indoor Plants to Freshen the Air.

Photochemical smog. Photochemical smog is a type of smog produced when ultraviolet light from the sun reacts with nitrogen oxides in the atmosphere. It is visible as a brown haze, and is most prominent during the morning and afternoon, especially in densely populated, warm cities.

These sensors work on the principle of measuring the attenuation of infrared radiation (with a specific wave length) in the air. The sensors consist of an infrared radiation source, a light-water pipe and the infrared detector with the appropriate filter.
