People sometimes smell bad smells, but do these smells affect our health? I think it is possible to have an impact, but it should be judged according to the specific situation, for example, the smell of stinky tofu has little impact, but the smell of some viruses and bacteria has a great impact, so let's explain it to you in detail. <>
1.Most of the smells affect our health.
Our body has its own protective mechanism, the reason why some smells we smell is because the brain tells us that these things are not good for our human body, if we don't stay away quickly, it may cause damage to us, that is to say, all the smells we smell in life are basically not good for our health. For example, rotten meat and rotten vegetables, if we continue to eat these things when we smell the stench, it will definitely have an effect on our body. <>
2.A small number of odors have little effect on our body.
For example, the smell of stinky tofu smells very bad, but it tastes very fragrant and has little impact on people's health. In addition, there are many other smells, such as the smell of smelly socks, which are some smells that have little effect on our body, so we don't need to worry too much. <>
3.The odor we smell is also very small particles, so it is normal to have an effect.
As we should have learned in physics class, matter is dispersed, and when a foul smell appears in the air, it will scatter and float around our nose, and when it floats around our nose, we absorb it into our body, so we smell the smell. If substances are harmful to the human body, then the tiny particles formed by these substances will also have an impact on the human body.
All in all, the smell of some environment may be harmful to our body. Because our body has a protective mechanism, most of the odor we smell will damage human health, and there are also a small number of parking spaces, which have little impact on people, such as stinky tofu, such a smell, we don't need to worry too much.
-
Smell can affect our health to a certain extent, and when we smell it, it can cause us discomfort, and even our head hurts, and it can also affect our mood.
-
I think the smell will affect health, such as the smell of the toilet, not to death of people, so don't stay in a smelly environment.
-
Odor will definitely affect our health, if we stay in this smelly environment for a long time, then the body's internal organs will be polluted, then it will affect the endocrine.
-
If we smell too much, our nose will not be smooth, and the nose sense of smell will fail, causing rhinitis. In some smelly places, it is better to wear a mask.

How dangerous are the smells you thought they were?
If you think about it, where do all the stenches we often smell come from? Is it either a kitchen or a toilet? Of course, it is not excluded that it is someone next to you.
But in fact, these smells are quite safe, unlike some dangerous smells, such as the smell of rotten eggs from the toilet. Isn't it normal for the toilet to smell like this?
No, it's normal for the toilet to smell, but it's not normal to smell rotten eggs, because it's most likely the smell of hydrogen sulfide. This situation is generally caused by your toilet not being cleaned for a long time and the moisture level is low, but don't underestimate this situation. It is said that a couple who died suddenly in the toilet of a post-95 couple died suddenly because the toilet was low in moisture and was caused by hydrogen sulfide poisoning caused by uncleanness.
Secondly, the smell in the kitchen is more frequent. For the kitchen, there are generally two smells, one is the sour smell caused by food spoilage, and the other is the special odor emitted by the rancid agent in the gas. If you smell a peculiar odor, you should be careful, as it could indicate a gas leak in your home.
Some people may think that natural gas is not poisonous, what should I be wary of? It is true that natural gas is not as toxic as carbon monoxide, but when natural gas reaches a certain concentration in the air, it can cause hypoxic suffocation in the human body. Secondly, natural gas, as a fuel, will enter the limit when mixed with air under certain conditions.
You heard it right, it's **. The first limit of natural gas is 5%-15%, if the concentration is in line with it, and there is a fire source in the indoor space, the gas in the entire space will detonate, and human beings have no time to react, so how can we prevent accidents?
First of all, for the sake of safety, we need to use gas appliances that meet national standards, and regularly inspect and replace gas hoses. If you notice a special smell in the kitchen, you should check whether the electricity and gas are leaking. So how do we check if the gas is leaking?
In the national safety science popularization action, professionals gave the answer. We can apply soapy water to the joints of the pipes, and if bubbles appear, there is a leak. At this time, we must close the main valve as soon as possible, cut off the air source, and then quickly open the doors and windows for ventilation.
Remember to eliminate the supply of goods during the period, do not operate the emergency switch indoors, and wait until you evacuate the room, and finally call ** for help.

Be careful if you smell rotten eggs in the toilet, it could be hydrogen sulfide. Be careful if you smell a foul smell in the kitchen, it may be a rancid agent in the gas, and check if the gas is leaking.
-
In fact, it is particularly dangerous, and there are some toxic gases that smell like this, which is likely to cause poisoning.
-
For example, if you inhale too much durian, it may cause our respiratory tract to be blocked and poisoned. In addition, stinky tofu actually has the smell of rottenness.

When decorating a house, using materials that meet the standards is only the most basic requirement. If the decoration design and decoration process are not scientific, it will also cause environmental pollution in interior decoration. For example, when decorating flooring, experts will advise you not to lay all-wood floors or all-floor tiles.
Instead, some rooms should have wooden floors, while others could use floor tiles. Because, even if the decoration materials you choose meet the standard, the use of a large amount of wood flooring per unit area may lead to excessive formaldehyde, and the use of large area of floor tiles may lead to excessive radioactive materials. Among several harmful substances that cause environmental pollution in interior decoration, formaldehyde and ammonia have a strong pungent odor, which is easy for the human body to feel.
Radioactive substances like radon are colorless and odorless, and are not easily felt, but they are very harmful to people.
Radon is found in construction cement, slag bricks, decorative stones, and soil. Its main harm to the human body is lung cancer, which is the second leading cause of lung cancer after smoking. Households with excessive indoor air pollutants should not only ventilate frequently, but also appropriately place green plants such as chlorophyll, tiger tail orchid, and aloe vera in their homes for adjustment and treatment.
The placement of activated charcoal or the use of air purifiers also play a role. It should be reminded that after the activated carbon is saturated by adsorption, it will no longer have adsorption capacity. With the change of temperature and humidity, the adsorbed pollutants may be freed out, causing secondary pollution to the indoor environment, so it should be replaced regularly.
Not all materials used are qualified and do not cause indoor pollution. Indoor pollution is actually a process of "superimposition". Even if any material is tested to be qualified, it may emit polluting gases that exceed the standard.
Newly renovated houses will more or less have indoor air pollution such as formaldehyde, and the degree of pollution is closely related to decoration materials, decoration construction, decoration complexity, housing layout, etc. As we all know, formaldehyde may exceed the standard if it is not smelled. Formaldehyde is harmful and has a deep impact, and there are many studies at home and abroad.
However, the probability of leukemia and even cancer from exposure to formaldehyde is very low, but it is very common for some people to destroy the body's immune system and respiratory system, but some people are not aware of it or do not pay attention to it. Formaldehyde has a strong pungent and pungent odor, damp and mildew odor, etc. The smell you can smell is closely related to your own sensitivity and level of pollution.
-
I think this is a wrong statement, you can't smell the smell can only say that the pollution is smaller, it doesn't mean that there is no pollution, all kinds of pollution still exist, slowly in the volatilization.
-
Well, it's too general, the key is to look at the smell.
-
A: I don't think that the smell doesn't mean that there is no pollution in the room, and I think some pollution sources are colorless and odorless.
-
I think this is not correct, many harmful substances are colorless and odorless, it is not that they can't smell the smell, the room is safe and pollution-free, and it should be determined by special testing.

Odor is one of the mandatory items to test the water quality of raw water and treated water. Water odor is mainly due to the decomposition of pollutants and natural substances in domestic sewage and industrial wastewater or related microbial activities. Because most odors are too complex and the detectable concentrations are too low, it is difficult to separate and identify odor-producing substances.
1 Proliferation, death and decay of animals, plants and microorganisms in water;
2. Dissolved gases: such as hydrogen sulfide, biogas, etc.;
3. Mineral salts: such as iron salts, manganese salts, etc.;
4. Industrial wastewater: such as industrial wastewater containing phenol, coal tar, etc.;
5 Chlorine: When drinking water is disinfected with chlorine, if too much chlorine is used, it will also produce unpleasant odors, especially when the water contains phenols, and the chlorophenol odor will be even worse.
Although odorless and tasteless water is not guaranteed to be safe, it is good for drinkers to trust in the quality of the water. Odor testing is also a means to evaluate the effectiveness of water treatment and track the source of pollution. Methods for determining odor include qualitative descriptive method and approximate quantitative odor intensity method (odor threshold test).
Qualitative descriptive approach.
The main points of this test method are: take 100ml of water sample in a 250ml Erlenmeyer flask, the inspector relies on his sense of smell, respectively 20 and after boiling and slightly cold, smell its odor characteristics, use appropriate words to describe its odor characteristics, and report the intensity of odor according to the grade divided in the following table.
Grade Strength Description.
0 None No smell of any kind.
1 Weak - Difficult for ordinary drinkers to detect: perceive, smell sensitive to the bite.
2 Weak Ordinary drinkers can just notice.
3 Obvious can be clearly perceived, untreated, not drinkable.
4 strong has a noticeable odor.
5 Very strong has a strong foul odor.
Odor threshold method. This method dilutes the water sample with odorless water until the lowest discernible odor concentration (called the "odor threshold") is smelled, which is used to indicate the odor threshold. The dilution factor when the water sample is diluted to just smell the odor is called the "odor threshold", that is, the key points of the inspection operation: prepare the water sample dilution series in an Erlenmeyer flask with a water sample and odorless water (the dilution factor should not be known to the inspector), and heat it to 60 1 on a water bath; The inspector takes out the Erlenmeyer flask, shakes it 2-3 times, destoppers, smells its odor, compares it with odorless water, determines the dilution sample that just smells the odor, and calculates the odor threshold.
If the water sample contains residual chlorine, it should be tested before and after dechlorination. Due to the difference in the olfactory sensitivity of the inspectors, the test results of the same water sample dilution series will be inconsistent, therefore, more than 5 olfactory sensitive personnel are generally selected to test at the same time, and the geometric mean of the test results of each odor detector is taken as the representative value.

Of course, it is harmful to the human body, because it is also a kind of environmental pollution, such as stinky ditches and garbage are inevitable, but corresponding measures can be taken to reduce them.

The foul smell in the mouth is mostly due to stomach heat. Periodontal inflammation, gingival discharge, oral erosion, decay and fermentation of food debris along the gingival edge, purulent tonsillitis, and pus in the tonsil crypts can all have a foul odor in the exhalation. When atrophic rhinitis, paranasal sinusitis, nasal tumors, or foreign bodies are present in the nasal cavity, due to local inflammation and increased secretions, there is a large amount of pus necrotic tissue and a large number of bacteria, and when you breathe through the nose, the nasal cavity will emit unpleasant nasal breath.

If you have a bad smell, you may be deficient in zinc.
The environmental factors that affect the financial management of enterprises include the macro environment of financial management such as economic environment, legal environment, social and cultural environment, and the micro environment of financial management such as enterprise type, market environment, procurement environment, and production environment, which are also one of the main factors affecting financial management objectives. >>>More
If you look like this for a long time, it will definitely cause depression, and sometimes it will also cause psychological anxiety, and emotional upset will have a great impact.
No, at least, it is impossible for a long time, although monkeys are very similar to humans, and they are constantly evolving, but human civilization has been developing for countless years, and in a short period of time, they cannot catch up, and evolution, is an extremely long thing, even if one day monkeys really evolve the same as humans, presumably at that time, human beings have also walked out of this solar system.
