Question

measurement of several of the air pollutants by the epa includes an amount measurement as well as a __________ measurement.
length
width
time
scent

Explanation:

When measuring air pollutants, the Environmental Protection Agency (EPA) considers both the amount of pollutants and the time - related aspects. Measuring pollutants over time helps in understanding exposure levels, trends, and compliance with standards. Length and width are spatial measurements not relevant to air - pollutant measurement in this context. Scent is a qualitative and not a standard quantitative or time - related measurement for air pollutants as per EPA protocols.

Answer:

time
