question

The average concentration of particulate lead in a city with highly polluted air is 5\mug/m^3. If an adult respires 8500 liters of air daily and if 50 per cent of the particles below 1\mumin size are retained in the lungs, calculate how much lead is absorbed in the lungs each day. Of the particu-late lead in urban air, 75 per cent is less than 1\mumin size.
