The U. S. Environmental Protection Agency (EPA) sets limits on healthful levels of air pollutants. The maximum level that the EPA considers safe for lead air pollution is 1.5 μg/m3. If your lungs were filled with air containing this level of lead, how many lead atoms would be in your lungs? (Assume a total lung volume of 5.60 L .)

Expert Answer

Step 1

The U. S. Environmental Protection Agency (EPA) sets limits on healthful levels of air pollutants such as lead. Lead is extremely toxic to human health.

Step 2

Total volume of lung = 5.60 L

convert L to cubic meter

1 L = 0.001 cubic meter

So, 5.60 L = 5.60 L x (0.001 cubic meter/1L)

                       = 0.0056 cubic meter

Maxium level set for lead by EPA = 1.5 ug per cubic meter

So, 

mass of lead in 5.60 L = (1.5 ug/cubic meter) x 0.0056 cubic meter
