1颗粒危害 :直径在 5～ 1 0 μm(PM1 0 )的细颗粒可到达支气管区 ,直径小于 5μm的微粒可达到肺泡区 ,最终导致心血管和哮喘病的增加 ;2二氧化硫危害 :二氧化硫浓度增高 ,可使哮喘病和心脏病加重 ;3氮氧化物的危害 :氮氧化物中的二氧化氮可引起咳嗽和咽喉痛 ,如果再加上二氧化 1 Particle Hazards: Fine particles with a diameter of 5 to 10 μm (PM10) reach the bronchial region, and particles with a diameter of less than 5 μm reach the alveolar region, eventually leading to increased cardiovascular and asthma attacks; 2 Sulfur Dioxide Hazards: Elevated Sulfur Dioxide , Can make asthma and heart disease aggravate; 3 the harm of nitrogen oxides: nitrogen dioxide in nitrogen dioxide can cause cough and sore throat, if coupled with dioxins
