Chapter 2.9, Problem 2.12YT
Sulfur dioxide (SO2) is released in the air when copper ore is smelted to make copper metal. Let’s assume that a woman living downwind of a smelter inhaled 44 μg of SO2 in an hour.
- a. If she inhaled 625 liters (0.625 m3) of air per hour, would she exceed the 1-hr average for the U.S. National Ambient Air Quality Standards for SO2? Support your answer with a calculation.
- b. If she were exposed at this rate for three hours, would she exceed the 3-hr average?
