小赵参加工作后,每天上下班都是乘坐公交车,他尤其喜欢乘坐带有空调设备的公交车,为此,有时宁愿在站牌处多等一会儿。原因其实挺简单,冬天冰天雪地,天寒地冻,普通公交车内像冰窖,让人感觉寒冷难耐;夏天酷暑日晒,骄阳似火,没有空调的公交车内似蒸笼,乘客经常是汗流浃背,有时还染得一身汗臭,尴尬不已。空调公交车内冬暖夏凉,好安逸。不过,最近在报纸上看到一则车内空气质量安全的报道,倒是有些动摇了他对空调车的情有独钟。行驶时,空调车厢处于相对封闭的状态,车内空气质量是否符合国家卫生标准?人们经常处于此环境对健康是否有害? Xiao Zhao to work, commuting every day are by bus, he especially likes to take the bus with air-conditioning equipment, and for this reason, sometimes preferring more waiting at the station signboard for a while. The reason is actually very simple, the winter snow and ice, cold and frosty, ordinary bus like the icehouse, people feel cold and intolerable; summer heat, sun, like no air conditioning in the bus like steamer, passengers often sweat, sometimes Also stained a sweat, embarrassed endless. Air-conditioned bus in winter and cool in summer, so easy. However, recently I saw a report on the safety of air quality in the car in the newspapers, but somehow shaken his soft spot for air-conditioned cars. When driving, air-conditioned cars in a relatively closed state, the car’s air quality is in line with national health standards? People often in this environment is harmful to health?
