What is the Toronto Air Quality Index?
The Toronto Air Quality Index (AQI) is a crucial tool that helps residents understand the air quality in their city. It provides a clear numerical value that indicates how polluted the air is on any given day. By tracking the AQI, you can make informed decisions about outdoor activities and necessary precautions for your health.
Understanding the Numbers Behind the Index
The AQI is measured on a scale from 0 to 500, with lower numbers indicating better air quality. For example, an AQI of 0 to 50 signifies good air quality, while numbers between 51 and 100 are moderate. As the numbers rise, the health risks increase, particularly for sensitive groups like children, the elderly, and those with respiratory conditions.
Impacts on Toronto Residents
Healthy air is vital for everyone, but poor air quality can have serious consequences. High AQI levels correlate with increased incidences of respiratory issues, heart problems, and other health challenges. In Toronto, residents should pay close attention to these numbers, especially on days when pollution is expected to spike, like during heat waves or heavy traffic periods. Being aware of the AQI can help you proactively protect your health.
