Using the formula: Dose = Exposure x Contact rate
Calculate the dose of nitrogen oxide a person would receive if she was breathing at a rate of 1.2 m³/hr and was surrounded by air containing 10 mg/m³ of nitrogen oxide for half an hour.

Question

Quizplus · Accepted Answer

The dose is calculated by multiplying the exposure (10 mg/m^3) by the contact rate (1.2 m^3/hr) and the duration of exposure (0.5 hr), resulting in a dose of 6 mg (10 * 1.2 * 0.5 = 6). However, there seems to be a misunderstanding in the options provided, as none directly match the calculated result. The closest correct interpretation based on the calculation would be option C, assuming a typographical error in the question or answer choices.
