There is a very sour smell in the air, what is the source of pollution?

This means that there are strong acidic gases in the air, mostly sulfur dioxide and nitrogen oxides, which react with water vapor in the air to produce very low concentrations of sulfuric acid and nitric acid.

Wait. Carbon dioxide.

It does not smell odor, and although carbon dioxide is also an acidic gas, it does not have a sour smell.

Acid rain. It is possible that the pollution is exceeded, and the source of pollution is the chemical plant.

This means that there are strong acidic gases in the air, mostly sulfur dioxide and nitrogen oxides, which react with water vapor in the air to produce very low concentrations of sulfuric acid, nitric acid, etc.

Carbon dioxide does not smell and although carbon dioxide is also an acidic gas, it does not have a sour smell.

Sulfur. Generally, it is sulfur dioxide and hydrogen sulfide emitted from the factory.

Sources of sulphur dioxide pollution.

Of course not, but some of the smell is not so obvious, the main source of pollution is formaldehyde in the paint, because just after the decoration, formaldehyde is relatively strong mixed with the smell of paint, you can smell, but even if you can't smell it, in fact, there are still in the air, it is best to leave the house vacant for about two weeks after the decoration is often ventilated, and put some pothos or something in it to absorb faster.

Not necessarily, the main source of pollution is formaldehyde in the paint, because just after the decoration, the formaldehyde is relatively strong mixed with the smell of paint, you can smell it, but even if you can't smell it, there is still something in the air, it is best to leave the house vacant for about two weeks after the decoration is often ventilated, and some plants and flowers will be absorbed faster, I hope it will help you.

1. If you can't smell the smell, it doesn't mean that there is no pollution, and some pollution can't be smelled. 2. In decoration, the main source of pollution is decoration materials, heavy metals, benzene, methanol and other pollution, and industrial glue is very easy to smell pollution. Therefore, the decoration materials must be carefully chosen.

I don't dare to say this, and some odorless gases make people unguardable, and they can cure people to death.

What is Formaldehyde? What does it taste like?

There are slight differences in the smell of formaldehyde on different objects: 1. The formaldehyde smell on furniture is the smell of sawdust, wood, and wood slag, which is emitted by the smell of wood mixed with formaldehyde. 2. The formaldehyde smell of the cloth and curtains is generally emitted by the formaldehyde smell mixed with the fabric, which is a little sour and pungent, like the smell of gasoline, but it is worse than the smell of gasoline and a bit like the smell of burnt plastic.

3. The paint smell on the furniture is a mixture of benzene, formaldehyde, and banana water.

If it is a floor tile, it is normal to have a fishy smell, it may be Shandong bricks, and my house is also like this, probably because my floor tiles are not too good. If it's a wooden floor, it's a quality problem. The wooden floor of our office is also paved, and the smell is particularly strong when it is just laid, and when I open the door when I go to work in the morning, it smells bad, and I have to open the window for ventilation.

But now it's okay. If you really can't stand it, buy some activated carbon, or spider plants, tiger pills and other things and plants that can purify the air, but it is best to keep the ventilation safe point and do an indoor air test! Another:

After the renovation of the new home, there will always be some peculiar smells, especially the strongest smell of paint, and some gases emitted by materials that we can't feel.

Dust, volcanic eruptions, forest fires, biodecay, mineral burning, etc.

1. Dust. Dust is an open source of pollution that enters the atmosphere due to the dust on the ground being blown by wind, man-made and other drives, and is an important part of the total suspended particulate matter in the ambient air.

2. Volcanic eruptions.

Volcanic eruptions emit large amounts of ash and volcanic gases, which have a great impact on the climate. Because in this case, dim daylight and storms and even mud rain can plague the local population for months. When volcanic ash and volcanic gases are ejected into the air, they are dispersed by the wind over long distances.

These gases can infect people's respiratory tract and are one of the main sources of air pollution.

3. Forest fires.

Forest fire refers to the forest fire behavior that is out of human control, spreads and expands freely in the forest land, and brings certain harm and loss to the forest, forest ecosystem and human beings.

Forest burning produces large quantities of smoke, mainly composed of carbon dioxide and water vapour, as well as carbon monoxide, hydrocarbons, carbides, nitrogen oxides and particulate matter. Except for water vapour, all substances above a certain limit can cause air pollution, which is harmful to human health and the survival of wild animals.

4. Biological decay.

rot, which means rotten; The organism is destroyed due to the growth of microorganisms. Decay, also known as spoilage, refers to the process by which animal proteins and their related organic matter are broken down into inorganic matter and returned to the natural material cycle, especially by oxygen-deficient microorganisms and decaying bacteria. Spoilage usually leads to the decomposition of amines with alkaloids such as carnitine and cadaverine, and has a putrefactive odor, which is one of the main sources of air pollution.

5. Mineral combustion.

Most of the pollutants produced by the combustion of fossil fuels are extremely harmful to human health. For example, suspended particulate matter can be inhaled, which can cause respiratory infections.

There are many types of industrial air pollutants, including soot, sulfur oxides, nitrogen oxides, organic compounds, halides, carbon compounds, etc. Some of them are soot, and some are gases.

2) Stoves and heating boilers: A large number of civil stoves and heating boilers in the city need to consume a large amount of coal, and the coal will release a large amount of dust, sulfur dioxide, carbon monoxide, and other harmful substances to pollute the atmosphere during the combustion process. Especially in winter, when heating, it often fills the polluted area with smoke and chokes people's cough, which is also a source of pollution that cannot be ignored.

3) Transportation: Automobiles, trains, airplanes, and ships are the main means of transportation in contemporary times, and the exhaust gases produced by burning coal or oil are also important pollutants. In particular, the number of cars in the city is large and concentrated, and the pollutants emitted can directly invade people's respiratory organs, which is very serious to the air pollution of the city, and has become one of the main sources of air pollution in the big city.

The exhaust gases emitted by automobiles mainly include carbon monoxide, sulfur dioxide, nitrogen oxides and hydrocarbons, and the first three substances are very harmful.

Hey, slow down, forget it, in my own experience, the main sources of pollution are the pollutants removed from the chimneys of industrial sources and the pollutants emitted by the means of transportation, especially the cars.

The main sources of air pollution are: sulfide gas, nitrogen gas, carbide gas, and dust particles.

The main pollutants in the air are sulfur dioxide, nitrogen oxides, particulate pollutants, and acid rain.

Carbon monoxide** in combustion, industrial production and transportation.

Carbon dioxide is the main cause of global warming. Carbon dioxide is mainly used in the production methods and lifestyles of industrial civilization: the combustion of oil, natural gas and coal; The destruction of forests and the absorption of soil organic matter by crops as a by-product of the nitrogen source process increase the earth's greenhouse gases (70% of carbon dioxide and 20% of methane).

Sulfide gas, nitriding gas, carbide gas, dust particles.

It is caused by volcanic eruptions and dust.

No matter what the reason or what you do, as long as you cause harm to the living environment and personal health of others, it is not allowed. It must be corrected immediately.

It's okay to keep a cat indoors. It is not illegal to keep a cat indoors. But he has a cat in his house.

You can talk to the head of the cat household and talk to him. The head of the household who has a cat often bathes the cat, cleans it, and does not disturb the neighbors. You have to talk peacefully with the owner of the cat household, and don't restrict him from having a cat.

Caring for animals should be protected. If you object to him having a cat, you have to communicate with the cat owner. Don't affect the neighborhood either.

First clarify the pollution source and wind direction, open the doors and windows in the opposite direction of the pollution source and all ventilation channels, close the doors and windows in the direction of the pollution source and all ventilation channels, and manually help discharge the indoor polluted air, such as indoor oxygen concentrators and air atomizers, which will be opened with confidence, and the indoor air will fully meet your requirements in less than a while.

There's a product in Hong Kong called AQ Air Purifying Spray that breaks down all the odor sources, and you can try it out in 10 seconds. I sprayed it in an ashtray with cigarette butts for more than 10 seconds, and I couldn't smell anything.
