AQI Air Pollution Level Health Implications Advice (for PM2.5)
0 - 50 Good Air quality is considered satisfactory, and air pollution poses little or no risk Enjoy the fresh air!
51 -100 Acceptable Air pollution is moderate; however, there is a health concern for very few people who are highly sensitive to air pollutants. People with respiratory disease like asthma, should not be outside for too long.
101-150 Bad for Sensitive People Sensitive people may experience some harmful health effects. Most people are not likely to be affected. Children, old people, and those with respiratory illness like asthma should limit prolonged outdoor activities.
151-200 Bad Everyone may experience health effects; sensitive people may experience more serious health effects. Everyone, especially old people and children, should limit prolonged outdoor activities. People with respiratory illness are advised to only go out when necessary.
201-300 Very Bad Extreme air pollution will cause everyone to be negatively affected with respiratory health issues. Everyone, especially old people and children, should avoid outdoor activities. Sensitive people with respiratory illness like asthma should not go out until air pollution is reduced.

Air Quality Index (AQI)

Air Quality Index or AQI is a value presenting air quality that ranges from 0 to 500. The higher value of AQI corresponds to the higher chance of getting air pollution and health concerns. AQI has six values listed below.

  • From 0 to 50: Satisfactory air quality

  • From 51 to 100: Acceptable air quality

  • From 101 to 150: Negative effect on sensitive groups

  • From 151 to 200: Negative impacts on the public generally; Serious health concerns for sensitive groups

  • From 201 to 300: Health alert!

  • From 301 and above: Emergency conditions!

Air pollutants: five major factors

According to EPA (the United States Environmental Protection Agency), there are five major pollutants when measuring AQI:

  • Particle pollution (also known as particulate matter, including PM2.5 and PM10)

  • Nitrogen dioxide (NO2)

  • Sulfur dioxide (SO2)

  • Ground-level ozone (O3)

  • Carbon monoxide (CO)

Air pollution - Facts, Causes, and Health concern

  • According to the World Health Organization (WHO), transportation is responsible for a large portion of urban air pollution. More than 80% of urban people, especially those from low- and middle-income countries, experience air quality levels beyond WHO limits. 91% of the world population settle down in areas having bad air quality.

  • Other factors responsible for air pollution are heating systems, fuel burning, agriculture waste, power generation, and industry.

  • Air pollution can kill about 7.0 million people around the world each year. 9 out of 10 humans inhale air with high pollutant levels.

  • Air pollution impacts health conditions and climate. People can experience lung cancer, acute respiratory illness, chronic obstructive pulmonary disease, stroke, heart disease, and so on. These health concerns eventually lead to around 4.2 million deaths worldwide.

Air pollution and Climate change:

  • Air pollution results in a lack of visibility, acid rain, ozone layer depletion, and global warming.
