Air quality advisory issued for Lower Mainland

VANCOUVER —  The latest heat wave across southern B-C has prompted an air quality advisory for Metro Vancouver and the Fraser Valley.

    The regional district of Metro Vancouver is warning of high ground-level ozone created when pollution from vehicles or other burned fuels reacts with the hot air.

    Those with chronic lung, heart or other medical conditions are most at risk and the regional district says temperatures will have to cool significantly before the advisory is lifted.

    Environment Canada’s Air Quality Health Index shows southwestern sections of Metro Vancouver currently have a rating of “7,” or “high risk,” but other regions of Metro Vancouver and the Fraser Valley are showing low to moderate risk levels this morning.
