冬雾伤人静悄悄说到冬季之害,早在1700多年前,享有医圣之誉的张仲景就已将其视为五种危害人体的邪气之一,称为雾邪。现代医学证实了张仲景的观点,查明雾中含有多种有害物甚至致癌物,如硫化物、氮化物、氟离子、有机酸、有机醛、苯、胺等。这些物质具有相当强的细胞毒性作用,随人的呼吸而侵人呼吸系统,对气管、支气管、肺组织等直接造成损害。健康人吸入雾气后,这些有害物可使大小气道的功能受损。而病人吸入后,有害成分则黏附于各级支气管及肺泡等处,引起反射性痉挛,加重慢性支气管炎、肺气肿与哮喘的病情。尤其糟糕的是甲基多环芳羟雾粒等强致癌物,尚有诱发肺癌之虞。以有“雾都”之称的重庆市渝中区为例,一份调查资料显示,在1984—1986年三年间雾日最多的月份,慢支炎、肺气肿、肺炎以及肺癌等疾病的死亡率占总死亡率的42.9%,其中肺癌死亡率居国内12大 Winter fog wound quietly talking about the harm of winter, as early as 1700 years ago, Zhang Zhongjing enjoys the reputation of medical Sheng has regarded it as one of the five kinds of evil that harm the human body, called fog evil. Modern medicine confirmed Zhang Zhongjing’s point of view, to identify the fog contains a variety of harmful or even carcinogens, such as sulfide, nitride, fluoride, organic acids, organic aldehydes, benzene, amines and so on. These substances have quite a strong cytotoxic effect, with the human respiratory and invade the respiratory system, the trachea, bronchus, lung tissue directly caused damage. When inhaled by healthy people, these harmful substances can damage the function of the small and large airways. The patient inhaled harmful components are adhered to the bronchial and alveolar levels at all levels, causing reflex spasm, increased chronic bronchitis, emphysema and asthma. Particularly bad is methyl polycyclic aromatic hydroxy fog particles and other strong carcinogens, there is the risk of inducing lung cancer. Take Yuzhong District, a city with the name of “foggy city” as an example. A survey shows that in the three months between 1984 and 1986 with the most foggy days, chronic myositis, emphysema, pneumonia, lung cancer and other diseases Of deaths accounted for 42.9% of the total mortality, of which lung cancer death rate ranks 12 in the country
