A feasibility study of the ozone formed from the oxidation of nitrogen dioxide in ambient air reported by the WHO suggested that daily deaths of 1 to 2% is attributed to exposure to ozone concentration above 47.3 ppb and exposure above 75.7 ppb is attributed to 3 to 5% increase in daily mortality. A level of 114 ppb was attributed to 5 to 9% ...
