ways to reduce exposure to air pollution

1 a report published recently brings bad news about air pollution．it suggests that it could be as damaging to our health as exposure to the radiation from the 1 986 ukraine nuclear power plant disaster．the report was published by the uk’s royal commission on environmental pollution．but what can city people do to reduce exposure to air pollution? quite a lot，it turns out（“結(jié)果是”/省略了to be）．

2 avoid walking in busy streets．choose side streets and parks instead．pollution levels can fall （降低）a considerable（相當(dāng)多的） amount（數(shù)量） just by moving a few meters away from （遠(yuǎn)離）the main pollution source—exhaust furies(廢氣)．a(chǎn)lso don’t walk behind smokers．walk on the windward(頂風(fēng)的)side of the street where exposure of pollutants(污染物)can be 50 percent less than on the downwind(順風(fēng)的)side．

3 sitting on the driver’s side of a bus can increase your exposure by 1 0 percent，compared with sitting on the side realest the pavement．sitting upstairs on a double—decked(雙層電車)can reduce exposure． it is difficult to say whether traveling on an underground train is better or worse than taking the bus．air pollution（空氣污染） on underground trains（地鐵） tends to（往往） be less toxic(有毒的)than(比) that at street level，because underground pollution is mostly made up of tiny iron particles(粒子)thrown up by wheels hitting the rails，while diesel(柴油機(jī))and petrol fumes have a mixture of pollutants．

4 when you are crossing a road，stand well back from the curb(路緣)while（當(dāng)...的時(shí)候） you wait for（等待） the light（交通等） to change（變化）. every meter really does（的確） count （重要）when you are close to（接近） traffic（車流）．a(chǎn)s（當(dāng)...的時(shí)候） the traffic begins（開始） to move（移動(dòng)），fumes can be reduced in just a few seconds. so holding your breath for just a moment can make a difference，even though it might sound silly（愚蠢的）．

5 there are large sudden pollution increases during rush hours．pollution levels（程度） fall（下降） during nighttime（夜間）．the time of year also makes a big difference．pollution levels tend to be at their lowest during spring（春天） and autumn（秋天） when winds （風(fēng)）are freshest（新鮮的）．extreme cold or hot weather has a trapping effect and tends to cause（造成） a build-up(堆積) of pollutants（污染物質(zhì)）．
