health hazard

Environment can generally be divided into big environment, such as the whole atmosphere. Smoking will pollute the environment and endanger human health.

In order to protect the environment and prevent related diseases, the body structure, river basin water quality and indoor microenvironment are studied in depth.

Local space within or near the range of human activities. Contribute.

Smoking is not enough to pollute the whole atmospheric environment, so what harm does smoke do to human body after polluting the environment?

Taoism. But the harm of smoking directly affects the old harm of smoking? According to reports at home and abroad and our investigation and study

Body, and polluted the small environment, and this small environment is just the analysis of the human body, as summarized below:

In places where activities are concentrated, the pollution of smoking to the small environment is 1, and the mortality rate of smokers is higher than that of non-smokers.

Some aspects greatly exceed the whole environment.

.

70% pollution; 2, smoking will significantly shorten life expectancy, starting from the age of 30.

The harm to people. Therefore, smoking is beneficial to human health. Smoking 40 cigarettes a day is 8-9 fewer than non-smokers.

Extremely harmful: especially for teenagers. But people are interested in this year. 3. The younger you start smoking, the lower the mortality rate.

There are many reasons for not paying enough attention to this issue, and the greater the impact; 4. The mortality rate increases with the prolongation of smoking history.

Most importantly, the harm caused by smoking to human hearing is slowly rising; 5. The more smoke inhaled, the higher the mortality rate; 6、

Sex, not obvious for a short time. Therefore, the mortality rate of smokers after quitting smoking increases with the extension of quitting time.

The environmental protection and medical departments have the responsibility to publicize and refuse.

First, the volume of cigarettes, the content of ingredients.

A variety of harmful components can be separated from flue gas, mainly including

Tar, nicotine, carbon monoxide, nitric oxide, hydrogen.

Cyanic acid and acrolein, etc. Gas accounts for 90% of smoke,

The rest is particulate matter including tar and nicotine.

Carbon monoxide is a toxic component, and the content of smoke is in

1-5%, carbon is generated in the blood after being inhaled by the human body.

Oxyhemoglobin can cause edema of arterial wall and form water.

Bubbles hinder blood circulation and are bad for platelets and cholesterol.

Deposition creates conditions that lead to arteriosclerosis.

Hydrocyanic acid can damage bronchial epithelium and its cilia,

Weaken its scavenging function and make harmful substances attach to epithelial cells.

Cause the proliferation and variation of cells to develop towards canceration.

Exhibition. Carcinogens in tar are polycyclic aromatic hydrocarbons and nitroso.

Amines and phenols. Nicotine is a substance that makes smokers addicted.

It acts on the nerve and adrenal gland in the transverse section, which makes the heart rate increase.

Cardiovascular and cerebrovascular diseases caused by high blood pressure.

Second, the relationship between smoking pollution and some diseases

1. Lung cancer: In the past 30 years, some countries

Statistics show that the increase in the number of elderly patients with lung cancer is relative.

When amazing, American male lung cancer patients from 17.6.

/65438+ ten thousand increased to 5 1/65438+ ten thousand. Britain, England

From 37.5/65438+ million to 7 1. 8/ 10

Wan. From the investigation materials of Fulaerji in Qiqihar City

Ming, more than 95% of lung cancer patients have a long history of smoking.

Historically, it is impossible to prevent lung cancer without smoking control.

2. Coronary heart disease: According to the epidemiology at home and abroad.

Retrospective investigation, animal experiment and prison observation proved that inhalation

Smoke pollution is an important factor leading to coronary heart disease.

There are independent factors as well as other factors such as hypertension and hypertension.

Cholesterol coordination, according to autopsy materials,

The coronary artery injury of smokers is more serious than that of non-smokers.

The severity of the lesion is related to the amount of smoking.

Smoke pollutes the environment, so do non-smokers

This is called passive smoking. Therefore, protecting the environment and controlling smoking, especially

It is of great significance to control smoking in public places.

2. Chronic bronchitis and emphysema: adjust according to the situation.

The survey shows that smokers spit more sputum than non-smokers. from

According to the investigation materials in Fulaerji District of Qiqihar City

More than 95% of patients with two diseases have long-term smoking history.

History. Teenagers are in the period of growth and development, and the respiratory tract is thin.

Cell resistance is weak and it is easy to suffer from respiratory diseases. In the atmosphere

In the case of serious environmental pollution, middle-aged smokers develop into

The chance of suffering from severe tracheitis increases, so environmental pollution and

Smoking has a coordinating effect.

Three. To study the relationship between sister smoking pollution and health.

Domestic and international trends

Since the 1950s, "smoking and health problems" have gradually

It has gradually attracted the attention of environmental and medical workers in various countries.

Table part of the article, 1962 Royal College of Internal Medicine.

The association submitted a report on smoking and health, and later submitted another report.

The second and third reports were submitted. World health

The Technical Committee of Organizational Health has affirmed smoking and lung.

Cancer, coronary heart disease, chronic bronchitis and emphysema are all related.

Very close relationship. Smoking cessation ratio in Sweden, Norway and other countries.

More successfully, the incidence of lung cancer has dropped. Some people are right about Hiro.

The smoking situation in a certain place in East China was investigated and analyzed, and the smoking was expounded.

Attention should be paid to the harm of smog and environmental pollution to human health

Meaning.

In order to improve human health, we should vigorously protect the environment.

Carry out smoking cessation and smoking cessation propaganda to improve human health.

Level.
