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