Extended data
Smoking in the airport not only affects the health of others, but also lays a safety hazard for your own health. The main hazards of smoking are:
1, carcinogenicity
Smoking is one of the important pathogenic factors of lung cancer, especially squamous cell carcinoma and small cell undifferentiated carcinoma. PAHs in tobacco smoke are cytotoxic and mutagenic only after being metabolized by PAH hydroxylase, and the concentration of this hydroxylase in smokers is higher than that in non-smokers.
2. Influence on cardiovascular and cerebrovascular diseases.
Smoking is the main risk factor of many cardiovascular and cerebrovascular diseases, and the incidence of coronary heart disease, hypertension, cerebrovascular disease and peripheral vascular disease of smokers has increased significantly.
Smokers are prone to arteriosclerosis obliterans and thromboangiitis obliterans. Smoking will lead to chronic obstructive pulmonary disease, and eventually lead to pulmonary heart disease.
3. Effects on respiratory tract
Smoking is one of the main causes of chronic bronchitis, emphysema and chronic airway obstruction. Long-term smoking can damage and shorten the cilia of bronchial mucosa and affect the cilia clearance function.
4. Effect on digestive tract
Smoking can increase gastric acid secretion, inhibit pancreatic secretion of sodium bicarbonate, increase duodenal acid load and induce ulcer.
