According to Professor Gauderman, children are more likely to develop respiratory problems if they live______.
(29)Professor Gauderman of the University of Southern California Medical School co-authored a study of children who live within 500 meters of a busy thoroughfare. What he discovered was that lung capacity in these children was far weaker than in those kids who live at least 1,500 meters away. That sets up a greater risk for childhood respiratory problem, like asthma.(30)Because lung development stops when children stop growing, the researchers were also concerned about their health as adults. Respiratory problems in adulthood can lead to other illness, such as heart disease and emphysema. Professor Gauderman says health and planning experts should take measures now to solve this looming problem.
