Question

when air pollutants are measured by the epa, the amount of the pollutant is measured. in addition, what else is measured? the color of the pollutant the amount of time the pollutant is present

Explanation:

When measuring air pollutants, the Environmental Protection Agency (EPA) not only measures the amount of the pollutant but also the amount of time the pollutant is present. This is because the duration of exposure to a pollutant can significantly impact its effects on human health and the environment. For example, a high - concentration pollutant present for a short time may have different consequences than a lower - concentration pollutant present for a long time. The color of the pollutant is generally not relevant to its impact or regulatory measurement.

Answer:

the amount of time the pollutant is present
