What s in the smoke, what s in the smoke

Hazardous substances, tar, nitrosamines, cadmium, etc. First and foremost is nicotine.

Nicotine and tar are both harmful substances!

Carbon dioxide, nicotine, tar.

Cigarette tar and nicotine are harmful substances to the human body.

Summary. Hello, the components of cigarettes are 1, tar is the product of aerobic combustion of organic substances in cigarettes. It includes some hydrocarbons and mixtures of oxides, sulfides and nitrides of hydrocarbons, as well as some heavy metals such as chromium, cadmium, arsenic, etc.

2. The smoke mainly includes carbon monoxide, hydrocyanic acid, nitric oxide, nitrogen dioxide, acetone, acetaldehyde and other gases. 3. Nicotine There is information that the nicotine content in a cigarette can poison a mouse, and the nicotine in a pack of cigarettes can poison a cow.

What is the meaning of life?

Hello, people live for love, whether it is family, friendship, love is love. Everyone must have its meaning in the world, and only when there is a cause can there be an effect, and we must take responsibility for our own cause.

Refers to the smoke of smoke, which is the product of incomplete combustion of some fuels, especially some solid fuels are difficult to fully combustion; Refers to cigarettes, which are made from dried tobacco and contain toxic ingredients, and the cigarettes that are lit contain more than 4,000 chemicals, most of which are carcinogens.

1.Refers to the product of incomplete combustion of certain fuels.

Most fuels are made up of carbon, hydrogen, oxygen, nitrogen, and a small amount of sulphur and possibly some mineral ash. If these fuels are burned completely, the final products should be carbon dioxide, water vapor and free nitrogen, which are harmless. If the fuel contains sulfur, it also produces a small amount of sulfur dioxide when burned, which turns into a corrosive acid when it comes into contact with air and water.

To be fully combusted, the fuel must be given enough air to adequately oxidize at high temperatures. Such conditions are difficult to achieve, especially for solid fuels, and as a result, smoke is produced. Anthracite and coke do not emit smoke when burned because they do not contain volatile substances.

Anthracite, however, decomposes at a very low temperature, releasing various gases and coke substances, which combine with dust and dust to produce smoke.

The air in any city is filled with suspended solid particles. But it's not all smoke, it may also contain dust, substances emitted by plants, and other things. All of these things are gradually deposited by gravity.

In small towns or on the outskirts of large cities, this sediment can reach thirty or forty tons per square mile in a year. In large industrial cities, it can be 10 times larger!

Smoke can be extremely harmful. It harms health, destroys property, harms plants. In large industrial towns, it reduces the intensity of sunlight, especially ultraviolet rays, which are essential for human health.

If there were no winds to blow away the middle-aged smog, large industrial cities would probably be shrouded in smoke every day. In fact, in smog-filled areas, mortality from lung and heart disease tends to rise year on year. Smoke is more harmful to plants, because it blocks the sunlight needed by plants and prevents plants from "breathing".

What's more, the acid in the smoke directly destroys the plant! Today, many cities are taking aggressive action to reduce soot or find ways to reduce its harm.

2.Cigarettes are made from dried tobacco.

After chemical dust bridge treatment, a lot of added ingredients are added. Cigarette smoke contains about 4,000 chemicals, many of which are toxic, mutagenic and thousands of carcinogens.

Radioactive isotopes are one of the causes of lung cancer in cigarette smokers. Polonium-210 from cigarettes cannot be excreted from the body. It can enter the blood vessels and cause lesions of the heart, liver and stomach. Cigarettes also have radium-226 and lead-210.

Radioisotopes are derived from mineral fertilizers. Radioisotopes have been found in smokers in the 60s and 80s. The smoke from lit cigarettes also contains carcinogens such as nitrosamines and benzopyrene.
