What gases are common with foul odors? What are the 8 major odorous gases?

Ammonia. Trimethylamine, hydrogen sulfide, methyl mercaptan, methyl sulfide, dimethyl disulfide, carbon disulfide, styrene, etc. are all common gases with foul odors.

The common foul smell is liquefied gas, and there is natural gas, they will have such a smell, and this smell is relatively pungent, at this time we should know that this gas has been dispersed in the air.

Ammonia, hydrogen sulfide, methyl mercaptan, methyl sulfide, dimethyl disulfide, trimethylamine, carbon disulfide, styrene, etc., VOC values will also be added during monitoring.

Indoles: manure treatment, domestic sewage treatment, coking, meat decay, slaughtering livestock;

Nitro: fuel, explosives;

Hydrocarbons: oil refining, coking, petrochemical, calcium carbide, chemical fertilizer, internal combustion engine exhaust, paint, solvent, ink printing;

Aldehydes: oil refining, petrochemical, pharmaceutical, internal combustion engine exhaust, garbage disposal, casting;

Hydrogen sulfide: production or processing of kraft pulp, oil refining, coking, petrochemical, gas, manure treatment, carbon disulfide;

Mercaptans: kraft pulp, oil refining, gas, pharmaceutical, pesticide, synthetic resin, synthetic fiber, rubber;

Sulfides: kraft pulp, oil refining, pesticides, garbage disposal, domestic sewage sewers;

Ammonia: nitrogen fertilizer, nitric acid, coking, manure treatment, meat processing;

Amines: aquatic processing, animal processing, leather, bone glue.

Eight odorous gases, including hydrogen sulfide, hydrogen selenide, hydrogen telluride, sulfur dioxide, selenium dioxide, tellurium dioxide, ammonia, phosphine and so on.

In addition, odorous gases are not necessarily toxic gases, and toxic gases are not necessarily foul-smelling, such as carbon monoxide and nitric oxide are colorless and odorless gases, but it is also a toxic gas.

According to the "Odor Pollutant Emission Standard", the standard clearly stipulates that the eight odorous gases are hydrogen sulfide, ammonia, trimethylamine, methyl mercaptan, methyl sulfide, carbon disulfide, styrene, and dimethyl disulfide.

The eight harmful gases refer to all eight harmful pollutants in the GB14554-1993 "Discharge Standard for Harmful Pollutants", including hydrogen sulfide, dimethyl disulfide, trimethylamine, methyl sulfide, styrene, methyl mercaptan, carbon disulfide and ammonia.

The eight odorous gases refer to all eight odorous pollutants in the GB14554-1993 "Odor Pollutant Emission Standard", including hydrogen sulfide, dimethyl disulfide, trimethylamine, methyl sulfide, styrene, methyl mercaptan, carbon disulfide and ammonia.

Causes of bad breath and ** methods:

There are many causes of bad breath, which can be roughly divided into two main categories, one is the damage to the internal organs, gastrointestinal metabolism, and immune dysfunction caused by bad breath, and the other is the respiratory system and oral diseases that cause bad breath. In addition to these two major physical factors, smoking and psychological factors can also lead to the causes of bad breath.

** Ways to have bad breath:

The causes of bad breath, among which the body's visceral function, gastrointestinal metabolism, and immune disorders are the main causes, and the best method of bad breath should be based on your own situation to make a reasonable plan, if it is an internal cause of the body, you can take some drugs to regulate the metabolic function and immunity in the body. If it is not the internal cause of the body, nor is it the cause of diseases such as rhinitis or diabetes, but the oral problem is much simpler, first ** oral disease, and then pay attention to diet and oral hygiene, basically it can be solved quickly.

Advice: You go to the dentist first to rule out oral problems, then check your blood sugar and stomach, and the regular problems are here. You can communicate the results of the examination with me again! Wishing you good health!

There are many causes of bad breath, such as oral cavity, rhinitis, gastrointestinal problems, etc., but most of the bad breath is usually caused by gastrointestinal problems.

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.
