March 21, 2012
Effective immediately a Smog Advisory has been lifted by the Ministry of the Environment for the following forecast region:
- City of Hamilton
A change in weather conditions is causing improving air quality in Hamilton.
- A Smog Advisory is related to the Air Quality Index (AQI), which rates how clean the air is. The AQI scale ranges from 0 to 100+. Higher numbers mean higher health risks.
- A Smog Advisory is issued in your region when the AQI is expected to reach 50 in the next 24 hours. It can be lifted once the AQI is expected to reach or drops below 50.
- Smog is made up of a complex mixture of air pollutants that are sometimes visible, such as a brownish-yellow haze over cities; sometimes not. The two main ingredients of smog are ground-level ozone (O3) and fine particulate matter (PM2.5).
- Smog is harmful to the lungs and heart. Even in healthy people, smog can reduce lung function.
