Can scent cause cancer? I heard that there are benzene homologues in it

Perfume is also something that some people love and some hate. One woman said she quit her job because of perfume. I used to work in a foreign trade company, and most of my female colleagues used perfume every day, and they would sneeze when they smelled perfume.

In desperation, I had to change to a new job.

Sneezing and dizziness when smelling certain scents is a typical allergic reaction. At present, fragrance pollution has also become a standard term, specifically referring to the continuous and difficult to eliminate fragrance in public places and office areas, which in turn leads to respiratory reactions, dizziness and other uncomfortable symptoms in people who smell these fragrances.

Fragrance** is the volatile substances present in the article, mainly polycyclic aromatic hydrocarbons and other compounds, long-term exposure to such substances can even cause cancer. In bread and other foods, the strong aroma mostly comes from additives such as flavors, and long-term smell will cause a decrease in people's sense of smell. If you are allergic to a certain fragrance, you must avoid contact with it, as long as you get rid of the allergen, it will not affect your health.

This is the case you are talking about.

It should be the right situation.

If there are many incense items, it is very likely that they are all toxic substances, so be careful.

Benzene has an odor that can be smelled.

Benzene is a colorless to light yellow transparent liquid with a strong aromatic odor, and is a volatile, flammable, insoluble in water, soluble in ethanol, hydrocarbons and many other organic solvents of toxic organic substances.

The aromatic smell of benzene resembles the taste of bitter almonds. The main ** of benzene is paint, mainly oil-based paint. There are also other uses for benzene, such as artificial perfume flavors, which can contain benzene.

The ring system of benzene is called benzene ring, and the structure of benzene ring after removing a hydrogen atom is called phenyl group, which is expressed by pH, so the chemical formula of benzene can also be written as phh.

Substitution reactions

The hydrogen atoms on the benzene ring can be replaced by halogens, nitro groups, sulfonic acid groups, hydrocarbon groups, etc. under certain conditions to form corresponding derivatives. Due to the different substituents and the different positions and quantities of hydrogen atoms, isomers with different numbers and structures can be generated.

The electron cloud density of the benzene ring is large, so most of the substitution reactions that occur on the benzene ring are electrophilic substitution reactions. The electrophilic substitution reaction is the representative reaction of the aromatic ring. When the benzene substitute is electrophilically replaced, the position of the second substituent is related to the type of the original substituent.

Benzene can also be smelled with an odor. Benzene is a sweet, flammable, carcinogenic and transparent liquid with a strong aromatic odor at room temperature. Benzene is insoluble in water, soluble in organic solvents, and can also be used as an organic solvent itself.

Does benzene smell and can you smell it.

Benzene is a basic raw material for petrochemical industry, and its output and technical level of production are one of the indicators of the development level of a country's petrochemical industry.

The chemical formula of benzene is C6H6It is a hydrocarbon, i.e. the simplest aromatic hydrocarbon.

The ring system of benzene is called benzene ring, and the structure of benzene ring after removing a hydrogen atom is called phenyl group, which is expressed by pH.

It is sweet at room temperature.

Benzene is a hydrocarbon, the simplest form of aromatics. A colorless, transparent liquid that is flammable, carcinotoxic, and has a strong aromatic odor. Insoluble in water, soluble in organic solvents, itself can also be used as an organic solvent.

Industrial use

As early as the 1920s, benzene was a commonly used solvent in industry, mainly for metal degreasing. Due to the toxicity of benzene, benzene is no longer used as a solvent in the production process where the human body can directly contact the solvent.

Benzene has the effect of reducing knocking and can be used as a gasoline additive. Before tetraethyl lead was introduced in the 1950s, all antiknock agents were benzene. However, with the fading of leaded gasoline, benzene has been re-used.

Due to the adverse effects of benzene on the human body and the pollution of underground water quality, European and American countries limit the content of benzene in gasoline to no more than 1%.

The most important industrial use of benzene is as a chemical raw material. Benzene can be synthesized into a series of benzene derivatives:

A series of compounds produced by benzene substitution reaction, addition reaction, oxidation reaction, etc., can be used as raw materials for the preparation of plastics, rubber, fibers, dyes, detergents, pesticides, etc. About 10% of benzene is used as a basic raw material for the manufacture of benzene intermediates.

Yes. Benzene is a hydrocarbon, the simplest aromatic hydrocarbon, which is a sweet, flammable, carcinogenic and toxic colorless transparent liquid at room temperature, with a strong aromatic odor. Benzene is a good organic solvent with a strong ability to dissolve organic molecules and some non-polar inorganic molecules, and can be miscible with most organic solvents except for glycerol, ethylene glycol and other polyols.

Except for iodine and sulfur that are slightly soluble, inorganic substances are insoluble in benzene.

Due to the high volatility of benzene, it can easily diffuse when exposed to air. Acute and chronic benzene poisoning can be caused by inhalation or exposure of large amounts of benzene into the body by humans and animals. Long-term inhalation will infringe on the human nervous system, and acute poisoning will produce nerve spasm and even coma and death.

Benzene is an aromatic hydrocarbon, but not all aromatic flavors are chemically defined, and there may be other flavors, such as formaldehyde. So it's hard to say what exactly the smell is.

Yes, benzene is a hydrocarbon, simply put, an aromatic hydrocarbon, and has a strong fragrance at room temperature.

Benzene is a slightly aromatic organic solvent that has a wide range of industrial uses, but it has been found that benzene can cause acute poisoning, chronic poisoning, and even leukemia and malignant lymphoma. So how does benzene cause acute poisoning, chronic poisoning, and even leukemia and malignant lymphoma?

The first factor is the concentration of exposure to benzene.

Some workers brush benzene-containing paint or paint in unventilated cabins and basements, or use benzene-containing neoprene to glue leather shoes in unventilated workshops, which can inhale high-concentration benzene vapor in a short period of time, causing acute poisoning, headache, dizziness, nausea, vomiting, unsteady walking, like drunkenness, and serious cases are delirious and falling, which can cause death if not rescued in time.

The second factor is the time of exposure to benzene.

After a century of research, scientists have proven that long-term exposure to low concentrations of benzene can lead to aplastic anemia and leukemia. The main symptoms of chronic benzene poisoning are weakness, a decrease in white blood cells in the blood, a decrease in the body's immune function, and a decrease in whole blood cells (including white blood cells, red blood cells, and platelets) in severe poisoning patients, also known as aplastic anemia.

When it comes to leukemia, it is more serious, it is a malignant blood disease, mainly the malignant proliferation of naïve white blood cells in the bone marrow and blood, which is more than 10 times more than normal people. We have collaborated with the American Agency for Cancer Research for more than 10 years to prove that the incidence of leukemia and malignant lymphoma in workers exposed to low concentrations of benzene is significantly higher than that of the general population, and many leukemias are developed from patients with severe chronic benzene poisoning.

The third factor is genetic traits.

As we all know, not all workers who work in the same occupational environment develop poisoning or leukemia. In other words, some people have some genetic deletions, or mutations that are difficult to repair, thus weakening these.

Benzene is a widespread environmental pollutant in industrial cities, which has attracted widespread attention from scholars at home and abroad. Workers exposed to benzene are very common, and people who are exposed to benzene for a long time can cause chronic benzene poisoning, which is manifested as leukopenia, thrombocytopenia, and severe pancytopenia, which can develop into aplastic anemia.

There is no specific carcinogenicity rate. 】

Benzene is a carcinogen that is toxic and can be susceptible to leukemia if people are exposed to it regularly. Benzene is a slightly aromatic organic solvent with a wide range of industrial uses, but it has been found that benzene can cause acute poisoning, chronic poisoning, and even leukemia and malignant lymphoma.
