What smoke from combustion is good for the human body? And it smells good?

Rosewood, the ancients used this to make incense.

Tobacco smoke poses a huge threat to the health of residents, with thousands of chemicals, hundreds of harmful substances and 69 carcinogens in tobacco smoke. According to foreign statistics, the top three diseases of death caused by smoking are chronic respiratory diseases, coronary heart disease and lung cancer, while lung cancer ranks second in our country.

Smoke gases in fires can also cause loss of human inhalation. Inhalation injury refers to the inhalation of some chemical components in hot air, vapors, smoke, harmful gases, and volatile chemicals, which can cause damage to the respiratory tract and lung parenchyma, as well as systemic chemical poisoning caused by the inhalation of toxic gases and substances.

Mild inhalation injuries are mostly confined to the mouth, nose and pharynx, and clinically visible sputum containing charcoal particles, redness, swelling of the mouth, sometimes blisters, and slight pain and dryness in the larynx. Moderate inhalation injuries predominantly affect the pharynx, larynx, and trachea, and are often accompanied by hoarseness and redness and edema of the upper respiratory tract.

It is better to stay away from other chemical fumes and not risk your health.

1. Smoke can absorb light, hinder the propagation of light, affect visibility and line of sight, 2. Smoke contains a variety of harmful components, such as: carbon dioxide, nitrogen oxides, etc., which can produce suffocation, poisoning and other effects.

Hello, dear <>

Based on the questions you provided, the amount of smoke produced by the combustion of different substances depends on a variety of factors, such as combustion temperature, oxygen**, fuel type and chemical composition. Therefore can not simply what substances burn the maximum smoke.

In general, fuels with high smoke may include wood, rubber, plastics, and oils, among others. These fuels, when burned, release harmful gases and solid particulate matter, which can be a hazard to human health without proper ventilation and safety measures. Therefore, when using these fuels, it is necessary to pay attention to safety and try to choose low-smoke alternatives.

Summary. Hello <>

Tar burns with the biggest smoke. Tar is produced by tobacco when burned and is one of the most abundant harmful substances in smoke. Tar contains a variety of carcinogens, such as polycyclic aromatic hydrocarbons, aromatic amines and nitrosamines, which are extremely harmful to human health.

There are other harmful substances in the smoke, such as carbon monoxide, nitrogen oxides, etc. These substances will cause varying degrees of harm to human health.

What substances burn the most smoke.

Hello <>

Tar burns with the biggest smoke. Tar is produced by tobacco when burned and is one of the most abundant harmful substances in smoke. Tar contains a variety of carcinogens, such as polycyclic aromatic hydrocarbons, aromatic amines and nitrosamines, which are extremely harmful to human health.

There are also other harmful substances in the smoke, such as a trace of landslide oxygen, Xiaozhou slippery carbon, nitrogen oxides, etc. These substances will cause varying degrees of harm to human health.

Therefore, quitting smoking is one of the best ways to protect your health and reduce air pollution. In addition, we should also increase our understanding of the harmful substances of tobacco, and strengthen the supervision of Gabri to protect public health. <>

Hello dear, the size of the smoke produced during combustion depends on a variety of factors, including the type of fuel, the combustion temperature, the chemical composition of the combustion gas, etc. Under the influence of these factors, the combustion of different substances will produce different degrees of smoke and fog. Of all the substances, the smoke produced by the combustion of coal is one of the largest.

The main component of coal is carbon, which releases large amounts of carbon dioxide (CO2), carbon monoxide (CO) and other harmful gases (such as sulfur oxides, nitrogen oxides, etc.) when burned. Smoke from coal combustion has high levels of these harmful gases and other compounds, which can have a significant impact on the environment and health. Secondly, oil and gas also produce smoke when burned.

The main components of these substances are hydrocarbons, which produce a range of volatile organic compounds (VOCs) and other harmful gases when burned. These substances can also have a negative impact on the environment and health. In general, one of the substances that produces the most smoke when burned is coal.

Other carbon-containing substances, such as oil and natural gas, also produce a lot of smoke when burned, but this is smaller than that of coal. In daily life, reducing the burning of coal and other highly polluting fuels and using more environmentally friendly energy sources and fuels, such as natural gas, biofuels, and electricity, can effectively reduce smog and pollutant emissions.

Class A fire: refers to:Solid matter fires。This substance tends to be organic in nature and generally produces hot embers when burned. Such as wood, coal, cotton, wool, hemp, paper and other fires.

Class B fire: Refers to:Liquid fires and meltable solid matter fires。Such as gasoline, kerosene, diesel, **, methanol, ethanol, asphalt, paraffin and other fires.

Category C fire: refers to:Gas fires。Such as gas, natural gas, methane, ethane, propane, hydrogen and other fires.

Fire Classification

According to the Notice on Adjusting the Grading Standards for Fire Selling issued by the Ministry of Public Security on June 26, 2007, the new fire grading standards have been adjusted from the original three levels of extraordinarily large fires, major fires and general fires to four grades of particularly major fires, major fires, larger fires and general fires.

Particularly major fire: refers to a fire that causes more than 30 deaths, or more than 100 serious injuries, or direct property losses of more than 100 million yuan.

Major fire: refers to a fire that causes the death of more than 10 people and less than 30 people, or the serious injury of more than 50 people and less than 100 people, or the direct property loss of between 50 million and 100 million yuan.

Relatively large fire: refers to a fire that causes the death of 3 to 10 people, or the serious injury of 10 to 50 people, or the direct property loss of between 10 million and 50 million yuan.

General fire: refers to a fire that causes less than 3 deaths, or less than 10 serious injuries, or direct property losses of less than 10 million yuan. (Note: "above" includes this number, and "below" does not include this number.) ）

The biggest harm of moyamoya disease is that there will be some cerebral infarction, cerebral hemorrhage, and some chronic ischemia, which leads to some symptoms such as decline in intelligence and memory. Some patients may have bleeding or infarction to the hospital, but some patients only often have headache symptoms, sometimes memory loss, and many patients may not have symptoms of bleeding or cerebral infarction in their lives.

The probability of acute stroke such as cerebral infarction or cerebral hemorrhage is still relatively high, more than 70% 80%, that is, 70% of 80% of patients in moyamoya disease may cause stroke in different periods, that is, cerebral hemorrhage and cerebral infarction. Even if there are no symptoms such as stroke, stroke, cerebral hemorrhage, and cerebral infarction, some patients may suffer from chronic cerebral ischemia, intellectual disability, memory loss, early dementia and other symptoms due to long-term cerebral ischemia. It may be that these patients do not have bleeding or infarction, and they think that there is no disease, but in fact, the harm of functional diseases is relatively large.

Due to the different manifestations of moyamoya disease, the harm to the human body is also different, mild patients will have transient cerebral ischemia manifestations, dizziness, headache, limb numbness or limb weakness, limb function will appear transient disorders, severe and cerebral infarction or cerebral hemorrhage onset, causing coma, aphasia, and even death of patients. Therefore, moyamoya disease is one of the more serious cerebrovascular diseases, once the onset will seriously affect the health of the human body, and even endanger life, for the first phase of moyamoya disease, it begins with a chronic disease, and begins with an incurable disease, generally the first cycle is relatively long, to completely alleviate the moyamoya disease, it generally takes two to three courses of treatment to be alleviated. Moyamoya disease is manifested as transient cerebral ischemia, headache, epilepsy, limb weakness, paresthesia and visual field changes, while severe cases are caused by cerebral infarction or cerebral hemorrhage, resulting in hemiplegia, aphasia, coma and even life-threatening.

The harm is still relatively large, and the patient should be timely**. Patients with moyamoya disease should be timely**, preferably surgery**, combined vascular bypass surgery is currently the most effective method for moyamoya disease, and 90% of patients can return to a healthy life through surgery**.

Fog is a phenomenon of turbidity formed by the suspension of large amounts of smoke, dust and other particles. Generally speaking, fog formed for non-specific reasons (such as acid mist produced by the sulfuric acid industry, etc.) is harmless, while haze is harmful to the human body. To put it bluntly, fog in general is water, while haze is an aerosol formed by small solid particles.

There are thousands of chemical and radioactive substances and hundreds of harmful substances in the smoke, which can induce many respiratory diseases such as lung cancer, throat cancer, and esophageal cancer.

This condition is commonly known as "secondhand smoke". Secondhand smoke is no less harmful to passive smokers than active smokers, especially to children and adolescents. Hazards include:

Increases the chance of lung cancer; harden cerebral arteries and affect intellectual development; Causes asthma and pneumonia in children; Increases the risk of coronary heart disease, diabetes and more.

Being in a smoky environment often can lead to premature aging. When the harmful gases in the fire, soot, cigarettes, and dust are inhaled into the lungs through the respiratory tract and penetrate into the blood, it will bring great harm to people. Especially for smokers, when they inhale cigarettes into their lungs, nicotine, tar and carbon monoxide provide conditions for the deposition of cholesterol, which can cause arteriosclerosis and promote aging.

Smoke is very harmful to people's bodies, especially for the lungs and eyes. It can also be said that the respiratory tract is the most serious.

Smoke is a killer, and all smoke is dangerous. Half of all fires are caused by smoke inhalation and often occur at night. And those who managed to escape the fire suffered permanent damage to their lungs.

Remember, it's not just fire that kills.

Smoke is a mixture of various deadly gases, water vapors, and particles of partially burning materials.

It comes from the conversion of burning substances into gases. All fires release smoke, but the amount and nature of the smoke depends on the location of the fire and the substance on fire.

If a fire breaks out in a small, enclosed space, such as a cupboard or a small room, the oxygen needed for the fire is restricted, resulting in a very thick puff of smoke. However, if the fire occurs in a well-ventilated area, such as in a windowed room, more gases, water vapor and particles will be burned, resulting in lighter smoke.

Smoke damage to the lungs is the leading cause of death for fire victims. For example, people with simple burns of up to 80 degrees will survive, but those with combined burns of 20 degrees and inhaling large amounts of smoke will invariably die. Smoke can damage the lungs, making them impossible to recover.

The after-effects, although not immediately apparent, are terrible. Damage to the lungs can only be detected after a few days. Unfortunately, even if lung damage can be diagnosed immediately, doctors are powerless to do anything about the damage that has already been done.
