The air quality standard for O3 in the United States newly revised as of 1997 is a maximum 8-hour average O3 concentration of 84 ppbv not to be exceeded more than three times per year.
Most of us have heard of the ozone O3 layer which occurs naturally in the upper atmosphere and protects the earth from the suns rays. The Air Quality Standards Regulations 2010 set the target that that a three-year average of 8-hour mean concentrations of O3 should not exceed 120 µgm 3 more than 25 times. Are subsequently weighted by population-density for calculation of nation-level average. 0 No data 0 ppb 10 ppb 20 ppb 30 ppb 40 ppb 50 ppb 55 ppb 60.
