APFIVE Lead Exposure Calculation
A building is tested for lead exposure, and the ambient concentration of lead dust is measured at 0.015 mg/m³. If an individual inhales 10 m³ of air during an 8-hour workday, all of the following statements are true except:
A
Accurate measurements are crucial in assessing lead exposure and its associated health risks.
B
Multiplying the concentration (0.015 mg/m³) by the inhaled volume (10 m³) gives a total exposure of 0.15 mg.
C
A misplacement of the decimal point could result in an exposure estimate that is ten times too high.
D
The person is exposed to 1.5 mg of lead over the workday.
