Ventilation with outdoor air containing elevated ozone concentrations may complicate remediation attempts. [69] The WHO standard for ozone concentration is 60 μg/m 3 for long-term exposure and 100 μg/m 3 as the maximum average over an 8-hour period. [29] The EPA standard for ozone concentration is 0.07 ppm average over an 8-hour period. [70]
