What gas has a foul smell must not be toxic??? It s better to stink as much as you want!!

Ammonia, ozone, hydrogen sulfide, formaldehyde, some hydrocarbons and esters are all toxic odorous gases. Among them, a small amount of ozone is beneficial to the human body, and more is toxic.

Although stinky tofu is very nutritious, it can not be eaten more, in addition to the smell of toxic substances, there is also nitrite, which is very bad for the body to eat often.

Scents are actually mostly toxic. A perfumer once said that fragrance is tens of thousands of times diluted by the smell of the toilet. It is best not to use perfumes and fragrances for a long time.

The essential oil of pure plants is very fragrant, but it is actually poisonous and cannot be used in large quantities, otherwise it will cause poisoning of the nervous system, respiratory system, **, some organs of the body, and even death.

Smells are poisonous, and it's the body's defense mechanism.

However, there are some low levels of toxicity such as NH3 or ammonia, H2S (low concentration), carinth, and ethyl mercaptan.

The high purity of the stinky will never be forgotten.

Thiol. The smell of the weasel's farts is due to the presence of mercaptans (methyl mercaptan, ethyl mercaptan). People's sense of smell is very sensitive to the foul smell of mercaptans.

Therefore, factories producing coal gas and liquefied petroleum gas deliberately mix a little bit of this surprisingly smelly alcohol and sulfur into the fuel gas to act as an odor alarm, so that when they smell this odor, they can detect the presence of gas as soon as possible and take measures quickly.

Ozone, but if you inhale too much, it will be harmful, and a small amount is fine.

One of the ones added to the gas! Bromine.

The gas emitted by hairy eggs.

3-methylindole, commonly known as skatosin, has no obvious health toxicity to the human body, and has not been suffocated for a few days.

Yes, like ammonia. Pungent foul odor. But it doesn't do anyone harm.

But most of the smelly things are harmful to the human body. Just like the sense of taste, what tastes good is generally a good thing that is nutritious. And what feels bad taste is generally harmful.

It is a natural selection in human evolution. It may turn out that the number of people who like various flavors is about the same. But people who like smelly things (i.e., harmful things) die younger.

Their genes are more difficult to pass on. So it's less and less.

As long as you smell a pungent smell, it is poisonous! Such as: from life, small, from the iron, from the roadside ditch, we often iron, it is rubber, is it very pungent smell?

That's the toxic smell of burnt eraser! The roadside ditch will not stink if there is nothing rotting! When things rot, they go bad.

We all know that everything that spoils is inedible. So the smell is the same. This toxic gas is abundant in the city in the work area.

Therefore, the reason why modern people are always so susceptible to diseases is mainly due to the air (toxic gas) that we are indispensable for every day.

Eggs 2Yogurt (especially with yellow peach pieces.) I have personal experience) 3Tofu (I also have personal experience with this).

I guess the above stuff is because of protein spoilage, so it stinks.

4.Meat --- dividing line ---1Persimmon pepper (some people call it "steamed pepper") really, I don't believe you try it, it is estimated that it is the most smelly among the spoiled vegetables.

2.Cayenne pepper Same as bell pepper.

I don't know how it works, but it really stinks.

1. H2SE is currently the most odorous substance in the world H2SE is currently the most odorous substance in the world Hydrogen selenide is a colorless, flammable, and highly toxic gas with a very unpleasant odor. At about 160 or so, it decomposes into a red selenium precipitate in the air. It is liquefied and transported as a liquefied gas at a specific air pressure.

Rafflesia grows in tropical forests such as Java and Sumatra in Malaysia, Indonesia. It smells like a rotting corpse 3, the most foul-smelling 1st place in Sweden salted herring!

What exactly is the smelliest thing in the world?There is a ** abroad, the canned herring in Sweden is listed as the most smelly food, this kind of salted herring is very smelly, and you have to go outside to open the can, otherwise you have to use a plastic bag or water to open, notorious.

Colorless, odorless, toxic gas: carbon monoxide.

Colorless, odorous, toxic gas: hydrogen sulfide (rotten egg smell).

Colorless, odorless and non-toxic gases: carbon dioxide, nitrogen.

You can't tell the smell, and when you do, you're not going to faint.

Meat is rich in nutrients, but it should not be stored for a long time, and if it is left at room temperature for too long, the quality will change, and finally cause spoilage. The cause of meat spoilage is mainly the result of changes caused by the action of microorganisms. According to research, when the number of microorganisms in each square centimeter reaches 50 million, the surface of the meat becomes visibly sticky and can smell the smell of decay.

When the microorganisms in the meat are slaughtered, they invade the muscles from the blood and intestines, and when the temperature and moisture conditions are suitable, they will multiply at a high speed and cause the meat to spoil. The spoilage process of meat decomposes protein into peptone, polypeptides, amino acids, and further decomposes into ammonia, hydrogen sulfide, phenol, indole, skatosin, amine and carbon dioxide, etc., these spoilage products have a strong odor and are very harmful to human health.

Good morning, the odor belongs to the smell of some inorganic and organic compounds volatilized at room temperature by the human sense of smell, such as hydrogen sulfide from rotten eggs, butanediamine from decaying corpses, sulfide from liquefied natural gas, indole from feces and pyridine in coal tar, etc. The principle of their odor is different, for example, indole and pyridine are innate odors, hydrogen sulfide and butanediamine are proteins that are decomposed in complex biochemical reactions of bacteria, and most of the odors are derived from the molecular formula containing sulfur and nitrogen, especially the liquid low boiling point solvents of mercaptan, thioether and ammonia nitrogen, please refer to it as appropriate.
