Air Quality Index (AQI) is increasing day by day and the impact is affecting the climate a lot. The change in the weather condition has worsened air quality.

• Air is the Earth's atmosphere. Air around us is a mixture of many gases and dust particles. It is the clear gas in which living things live and breathe. It has an indefinite shape and volume. It has no colour or smell. It has mass and weight, because it is matter. The weight of air creates atmospheric pressure. There is no air in outer space.
• Air is a mixture of about 78% nitrogen, 21% oxygen, 0.9% argon, 0.04% carbon dioxide, and very small amounts of other gases.
• Air can be polluted by some gases (such as carbon monoxide), smoke, and ash. This air pollution causes various problems including smog, acid rain and global warming. It can damage people's health.
• The Air Quality data sources varies depending on the cities.

AQI LEVELS DEFINITION:

• Green: AQI (0 - 50) | Good
Air quality is considered satisfactory, and air pollution poses little or no risk

• Yellow: AQI (51 -100) | Moderate
Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.

• Orange: AQI (101-150) | Unhealthy for Sensitive Groups
Members of sensitive groups may experience health effects. The general public is not likely to be affected.

• Red: AQI (151-200) | Unhealthy
Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects

• Purple: AQI (201-300) | Very Unhealthy
Health warnings of emergency conditions. The entire population is more likely to be affected.

• Brown: AQI 300+ | Hazardous
Health alert: everyone may experience more serious health effects
