In the mid-20th century, as industrialization accelerated, so did air pollution.
Air quality is a crucial aspect of our daily lives that often goes unnoticed until it's compromised.
The goal was to provide a standardized way to measure and report on the levels of common pollutants in the air, such as ground-level ozone, particulate matter, carbon monoxide, sulfur dioxide, and nitrogen dioxide. On the other hand, an AQI of 301 to 500 is deemed 'Hazardous,' indicating a health warning of emergency conditions due to the entire population likely being affected.
However, there are instances when the AQI may not fully represent the air quality, especially during periods of heavy smoke. To address this, scientists in British Columbia have adjusted the AQI, introducing a system called AQHI-Plus in March 2021. This adjustment provides a more accurate representation of air quality during smoky conditions.
