There are hundreds of different fog atmospheric chemical composition of particulate matter. Among them include: organic aerosol particles, fuel, and automobile exhaust. It can directly enter and adhesion in the human respiratory tract and alveolar, cause acute rhinitis and acute bronchitis. For obstructive emphysema, bronchial asthma patients, such as fog weather condition of acute attacks. If this kind of environment for a long time, will also cause cancer.
It have an impact on the cardiovascular system. Pollutants in haze weather, low air pressure, easy to cause acute episodes of cardiovascular system. Such as heavy fog, the water vapor content is high, if people in the outdoor sports, can cause chest tightness, high blood pressure and other symptoms.
Haze weather can also lead to nearly formation ultraviolet ray is abate, infectious germs. Due to the lack, children lack of ultraviolet irradiation, vitamin D production, for the absorption of calcium, cause rickets in infants, growth slows down. Will directly affect people's mental health, mental laziness, depressed, etc. No wonder these days the mood will be so happy.
Point of view, to eliminate the fog, we should reduce waste emissions; Reduce the dust; Especially to do less drive a car, use public transit. In order to better tomorrow, let's start environmental action today, the blue sky, green water, green and quiet we need to create your own!
最近几天，天空都是阴沉沉地，看不到太阳，给人一种冷飕飕的感觉。你看：近处，半山电厂的两个冷却塔，若隐若现;远处的半山，没了踪影。还整天让人精神懒散、心情低落。报纸、电视都在宣传：近期雾霾严重，要尽量减少外出、少开窗户。可见雾霾严重污染空气，使空气质量下降，影响人体健康。我很想了解雾霾对人的危害，于是上网去查了一下，真是“不看不知道，一看吓一跳啊!”
雾霾有数百种大气化学颗粒物质组成。其中就包含：有机溶胶粒子、燃料和汽车废气等。它可以直接进入并粘附在人体呼吸道和肺泡中，引起急性鼻炎和急性支气管炎。对于阻塞性肺气肿、支气管哮喘等患者，雾霾天气会使病情急性发作。如果长期处于这种环境，还会诱发癌。
它对心血管系统有影响。雾霾天气中污染物多，气压低，容易引起心血管系统的急性发作。比如雾大的时候，水汽含量高，如果人们在户外运动的话，会造成胸闷，血压升高等症状。
雾霾天气还会导致近地层紫外线减弱，传染性病菌滋生。由于日照减少，儿童紫外线照射不足，体内维生素D生成不足，对钙的吸收减少，引起婴儿佝偻病，生长减慢。还会直接影响到人们的心理健康，让人精神懒散、情绪低落等。难怪这几天心情会这么不舒畅。
看来，要消除雾霾，我们要减少废弃物的排放;减少扬尘的行动;尤其要做到少开汽车，多用公交出行的方式。为了更好的明天，让我们今天就开始环保行动吧，蓝天、碧水、绿色、清静需要我们自己创造的!
