In exposure assessment, what does the intensity factor refer to?

Explanation:
In exposure assessment, the intensity factor means how much contaminant is present in the air that a person breathes. It reflects the concentration of the chemical in the breathing zone (for example, mg/m3 or ppm). The higher this concentration, the greater the potential dose when inhaled, since dose is driven by concentration multiplied by how much air is inhaled over time. Temperature and air movement can influence how a chemical gets into the air or how it disperses, but they describe other aspects, not the amount available for inhalation. Color has no bearing on exposure magnitude.
