An exceedance refers to the levels of a substance that surpass a defined standard or limit. In the context of ozone levels, a reading of 0.10 ppm indicates the concentration of ozone in the air. Whether this is considered an exceedance depends on the regulatory standards set for ozone concentrations in the environment.

Given that the answer states "No," this implies that a level of 0.10 ppm does not exceed the acceptable limit according to established air quality standards. In many jurisdictions, the regulatory limit for ground-level ozone is often set higher than 0.10 ppm, meaning that this level would be considered safe and compliant with air quality standards.

Understanding the context of local, national, or international regulations is crucial, as these may differ. However, in the absence of any specification that 0.10 ppm is an exceedance within those limits, the conclusion drawn here is that it does not constitute an exceedance.
