What should I do if I smell chemical gases in the outside air?

In this case, you should immediately look for the smell of **.

If there are factories next to it, especially chemical plants, then the problem is obvious......It is the smell of the gas emitted from the factory.

If there is no factory nearby, it depends on whether there are vehicles and personnel working around. It could be that they use something to do their work, and the smell of gas comes out.

If there is nothing nearby, then go into the house and look for gas and liquefied gas valves to see if they are leaking......If you can't figure it out, you can ask a neighbor to check the ...... together

Strengthen personal protection and wear N95 masks when going out.

First find out what chemicals smell, many chemicals are non-toxic. And we have a lot of chemicals in our recipes.

Smell the smell of chemical gases outside, if the smell is very faint, it's not a big problem, get out of here quickly. If the smell of gas is strong, quickly soak something like a cloth or handkerchief with water, plug it in your nostrils, and leave it slowly.

If you stay in the house, you must avoid inhaling chemical gases. If you want to be outside, you need to wear a gas mask.

What kind of chemistry.

There is a difference. During World War II, the Nazis used chlorine gas to kill Jews.

That is also in high concentrations, causing permanent damage to the lungs.

If you smell sour and don't know what the gas is, you don't know what the harm will be.

There's no way to know how to save your health.

This at least then wear a mask to protect against the injury in the continuation.

There are many kinds of sour taste in chemistry, such as sulfuric acid, hydrochloric acid, nitric acid, acetic acid (acetic acid), etc., each with its own taste. The best way to find out what kind of chemical you smell very pungent sour in the air is to smell and compare it with the samples of the various acids above to know what the chemical is. If you imagine it, you can't imagine it.

If it's emitted from a chemical plant, it's mostly sulfur dioxide and hydrogen sulfide, and when I read it, there was also a chemical plant next to it, and we asked what the ingredients were, and our chemistry teacher told us about sulfur dioxide and hydrogen sulfide.

Most of them are acid-base substances and have certain toxicity.

As long as you know the polluting gas that you take medicine to remove internally, you can use an air chemical filter to select the filter material corresponding to the removal of gas, and the purification and removal effect can reach 99%, and the purified air can reach the concentration required by the national standard, which will not affect the environment. We are specialized in air chemical purification, and can do emergency treatment of toxic gases. After adsorption treatment, it can meet the direct discharge standard.

The fresh air system is used with an air purifier and humidifier.

Don't try to filter the air and go back indoors to breathe.

The contaminants must be extracted and then disposed of. Plenty of fresh air comes in from the outdoors.

In the same way, the effluent from the sewage plant can no longer be processed into the waterworks for human use.

After the decoration of the new house, the windows should be opened for ventilation, and it is best to move in after a month, otherwise it will be extremely harmful to the body!

Just finished the decoration smell, you can know that there is toxic gas in it, after a long time, the temperature is light, you can't smell it, but the toxic gas still exists, because all kinds of decoration materials in your house are releasing toxic gases, it is recommended that you find a professional to test it for you, it is best to treat it immediately. Rest assured, the current treatment equipment is very advanced and can achieve one-time removal.

It's very simple, you can eat some black fungus (raw), which has a detoxifying effect, and you can eat some foods that protect the lungs, such as: pear, white radish (raw), fritillary.

Ideally, it would be the same, but in fact, the amount of gas coming out of each breath is naturally different. For example, if you take a deep breath, when you breathe normally, and when you breathe quickly, the composition of the gas that comes out is different, even if you do normal breathing, the gas content should not be the same. I think it's normal to be different, and it's a ghost to be the same, and it's a small probability event, such as two planes colliding or winning a 5 million lottery.

Let me give you another example, if you do two push-ups, can you guarantee that you will do the same amount the first time as the second time? No matter how small the difference is, right? That's all about push-ups too, why is the amplitude different?

Don't you think that's a ridiculous question?

As for the second problem, it is to look at the significant digits to the first digit, the first table takes the significant digits to the second decimal place, and the second significant digit is taken before the decimal point, or it can be said that the first table takes 4 significant figures, and the second table takes 2 significant figures, just this difference, just this difference, as if you read some books say =, some say = this difference, I don't know if you understand it. Thank you.

It's really hard to understand, I don't know which book you read the watch from. But the reason for the first table must be because of water vapor, it is obvious that the amount of water vapor in the inhaled gas is less than the exhaled gas, but the content of nitrogen is the same, so the decrease in oxygen must be less than the increase in water vapor and carbon dioxide, so the proportion of nitrogen will decrease, so it should be. As for why the proportion of exhaled air is different, that's a matter of the tabulator's data**, but as far as I know, it should be 78%.

I hope the landlord can understand what I mean.

Ammonia, hydrogen sulfide, formaldehyde, and most organic compounds can do the same.

Maybe it's sulphur dioxide, because I've choked on sulphur dioxide, and that's probably how I feel. But in the toilet, I think it may be ammonia, but the ammonia is not very pungent.

It is estimated that it is a sewer, or ** issued, if it is not for a long time, you can leave it alone.

I don't know.

It could be some organic matter burning.
