Aqi 2 5

AQI Calculator - AQI Calculator. DIRECTIONS: Choose the tab for AQI to Concentration or the tab for Concentration to AQI. Select a pollutant, then enter the AQI value or the concentration (in units).

Most of the stations on the map are monitoring both PM 2. PM data, but there are few exceptions where only PM is. PM1 temperature, humidity and noise data of your location, city and state. Based on several studies at both low and high pollution levels, the human health effects are believed to be. 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. 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 or no potential to affect public health, while an AQI value over 3represents air quality so hazardous that everyone may experience serious effects. Extremely High Levels of PM2. Steps to Reduce Your Exposure.

AQI does not include recommendations for PM2. Pollution is hazardous at these levels. Everyone should take steps to reduce their exposure when particle pollution levels are in this range. Discover AirVisual Map, live world air pollution and air quality index ( AQI ) interactive 2D animated map combining PM2.

AQI, governments use a machine called a beta attenuation monitor that estimates the number of micrograms (the mass or weight) per cubic meter of air. So the raw number is the number of micrograms. Particulate matter, or PM2.

EPA criteria air pollutants, is a mixture that can include organic chemicals, dust, soot and metals. This is less than the thickness of a human hair. Can you convert AQI to volumes or concentrations of PM2. PM(particulate matter less than microns in diameter), NOx (nitrogen oxides), SO or other pollutants in the air? I also realized that this is basic knowledge for someone.

Environmental Protection Agency and allows us to compare against U. For more information on PM2. Health Effects Statement PM2. Unusually sensitive people should consider limiting prolonged outdoor exertion.

Unhealthy for Sensitive Groups. Air Quality Index ( AQI ) PM2. Fairbanks Area SPM PM 2. AQI Map (Click a Station for air quality details.) Station Name PM 2. The AQI is EPA’s color-coded tool for telling the public how clean or polluted the air is, and steps they can take to reduce their daily exposure to pollution. The AQI converts concentrations for fine particles to a number on a scale from to 500.

EPA is changing the upper end of the range for the “Good” AQI category (an index value of 50) by setting it at the level of the revised annual PM 2. AQI is one of the best measures of air quality. And particulate matter smaller than 2. Forecast Discussion: As expecte PM and PM 2. Moderate AQI category yesterday. PLEASE NOTE: This data has not been verified by the TCEQ and may change. At Victoria, it was 2on Wednesday.

Commonly written as PM 2. They are even smaller than their counterparts PM , which are particles that are micrometres or less, and are also called fine particles. PM is also often referred to as aerosols. While the chemical composition of particulate matter is important, its size is the dominant factor when it comes to human health considerations.
