What percentage does the reported ozone level exceed the permissible limit?

To determine the percentage by which the reported ozone level exceeds the permissible limit, one typically uses the formula:

[

\text{Percentage exceedance} = \left( \frac{\text{Reported level} - \text{Permissible limit}}{\text{Permissible limit}} \right) \times 100

]

In this situation, a reported ozone level that exceeds the limit by 33% indicates that the amount surpasses the safe threshold by this specific proportion. This is significant since exceeding permissible limits for ozone can have detrimental effects on human health and the environment.

For example, if the permissible limit of ozone is set at a certain level (let's say 100 parts per billion), an exceedance of 33% would mean the reported level is approximately 133 parts per billion. This clearly illustrates the heightened risk associated with elevated ozone levels.

When interpreting or calculating such data, it is critical to understand that these percentages help inform public policy and health advisories concerning air quality and environmental standards. Thus, identifying that the exceedance is 33% accurately reflects the degree to which ozone pollution may impact health and ecological systems.
