Road pollution is a serious danger to children's health. Researchers from the University of California spent 13 years studying children who ived within 500 metres of busy roads. They found that most of the 3,600 children in the study had weak lungs. Researchers said this meant the children could have breathing problems for the rest of their lives. The main author of the study W. James Gauderman and his team conducted their research on youngsters who lived near busy roads and in high-pallution areas. Once a year, the team measured the children's lung power. It checked how much air the children could release in one breath and how quickly it could be released. The team found that by their 18th birthday, children who within 500 metres of a highway breezed out three per cent less air compared with children who lived one-and-a-half kilometres away. Further, the highway children's lung power was seven per cent weaker in the rate at which they could breeze out. Gauderman said that: «Even if you are in a relatively low regional pollution area, living near a road produces lung problems». About a third of the children moved away from busy roads during the study but stayed near the same area. Their lungs developed more healthily. F 1) Researchers monitored different chldren for 30 years. 2) The text doesn't say how many children in the study had lung problems. 3) Living near a busy road doubles the chances of lung damage. 4) Researchers tested the children's lungs on a monthly basis. 5) Children living 500 metres from busy roads had 30 % less lung power. 6) Living near a busy road is still bad even if it's in a low-pollution area. 7) Children who moved away from roads still suffered lung problems.
