Well the answer is yes-- the closer you are to the ground the more efficient is the inhalation of heavier airborne chemicals. Children are more vulnerable to the health hazards of these pollutants. Besides breathing a greater volume of air than adults relative to their body size, children being small and closer to the ground (as compared to adults) breathe in more of the heavier airborne chemicals than adults. They also have a higher heart rate, which allows substances that are absorbed into the blood to permeate tissues faster.
