As smoke from the Canadian wildfires continues to affect our area, meteorologist Lee Goldberg breaks down the Air Quality Index and what it means for us.The Air Quality Index is a scale used for daily reporting of how clean or polluted the air is, and what health effects might be of concern.
The AQI focuses on what you might experience if exposed within a few hours or days after breathing polluted air. The Environmental Protection Agency calculates the AQI using 5 major air pollutants regulated by the Clean Air Act:The AQI runs from 0 to 500. The higher the AQI value, the greater the level of air pollution and the greater the health concern.An AQI of over 100 triggers an alert for vulnerable groups.The air quality in New York City and across the northeast is the worst since record-keeping began in 1999 because of the wildfire smoke from Canada, officials said.
