How do you calculate pm10?

The daily PM2. 5/PM10 AQI is calculated by taking the 24-hour concentration average from midnight to midnight (Local Standard Time) and converting to AQI. 75%, or 18/24 hours of data are needed for a valid daily AQI calculation.

What is pm2 5 Made?

Dust, spores and pollen are some examples. PM2. 5 refers to particles that have diameter less than 2.5 micrometres (more than 100 times thinner than a human hair) and remain suspended for longer. These particles are formed as a result of burning fuel and chemical reactions that take place in the atmosphere.

Why is PM 2.5 Dangerous?

Fine particles (PM2.5) pose the greatest health risk. These fine particles can get deep into lungs and some may even get into the bloodstream. Exposure to these particles can affect a person’s lungs and heart. Coarse particles (PM10-2.5) are of less concern, although they can irritate a person’s eyes, nose, and throat.
