Can you drink rainwater? Can rainwater be drunk directly?

No, some people think that the rain is transparent and crystalline, the snow is white and flawless, and the rain and snow are very clean and can be drunk directly. But in fact, they are not clean and cannot be drunk directly. Water vapor is present in the air at all times.

These are oceans, lakes, rivers, pools, wetlands, clothes that haven't been dried, and so on. When they are exposed to sunlight, the water in them evaporates and becomes water vapor, which is scattered in the air. When the water vapor condenses to a certain extent, the buoyancy of the air can no longer bear it, and it will fall to the ground, forming rain.

In the process of "traveling" to the ground, the rain will bring many "little friends", such as the smoke particles emitted from the factory, the dust above the ground, and even the bacteria in the air will also take the opportunity to mix in. Therefore, when the rain fell to the ground exhausted, it was already dry. Therefore, of course, rainwater cannot be taken and drunk.

However, when rainwater seeps into the ground, it passes through a thick layer of sediment, which filters out dust and bacteria, and becomes clean, and the rainwater is stored underground and becomes groundwater. Well water and spring water are groundwater, and they are drinkable. In winter, after the heavy snowfall, the land is covered in silver, which is spectacular.

As the saying goes, "Ruixue is a good year". People look forward to snow days, believing that snow is the purest purifying thing in the world, and that cold snow can kill many bacteria that are not hardy, but in fact, snow is also unclean.

Put the snow in a clean container, and when it melts, you will see a lot of fine dust particles at the bottom of the container. Therefore, snow, like rain, cannot be drunk directly.

No, you cannot. When the rain fell, all the dust in the air gathered.

The rain fell from the sky and did not touch anything dirty, so it was clean. Such perceptions and practices are inappropriate. This is because:

Rain is not spotless. We know that rain is caused by the condensation of water vapor in the air (in the clouds) and the fall of water droplets. On the one hand, clouds and fog not only contain water vapor, but also contain a lot of dust, and when water vapor condenses, it inevitably condenses some dust into it. On the other hand, when raindrops fall from the sky, they will inevitably be contaminated with dust floating in the air, and the dust in the air is mixed with various pathogenic bacteria, viruses, parasite eggs, industrial exhaust gases, and harmful substances produced by spoilage organic matter.

Therefore, rainwater that looks clean is not clean, and drinking rainwater directly is easy to cause diseases and harmful to health.

Rain is formed by the condensation of water vapor in the air on dust particles.

Heavy rain can lead to traffic jams, landslides, mudslides and other natural disasters. Acid rain can erode many buildings. (see "acid rain" for details) causing a road surface to slip, resulting in a car accident.

Rain can contaminate the groundwater by carrying toxic substances from the soil into the groundwater. Excessive rainfall can cause water levels in reservoirs, rivers and lakes to skyrocket, causing flooding.

It is not recommended to drink. Rainwater is formed by the evaporation of water vapor on the ground, and when it accumulates to a certain dose, it will start to rain, and its principle is similar to that of distilled water. In ancient times, rainwater was drinkable, but in modern society, air pollution is serious, and in some areas there is even acid rain, even if it is boiled and drunk, it is more harmful to the body than good.

There are impurities in rainwater, in areas with greater air pollution, rainwater also contains harmful substances, for the sake of the body, it is best not to eat rainwater to cook rice, and it is best to use tap water or mineral water for cooking, so that you will be more assured after eating.

The local air is good and you can wash clothes with rainwater, you can wash clothes with rainwater just now, rainwater contains natural minerals, there is no damage to clothing, but it should not be put for a long time, it is easy to breed small insects for a long time, and the place with serious air pollution should not do this, rainwater contains harmful substances after contacting ** is easy to cause discomfort.

Rainwater is not drinkable.

Scientifically speaking, when water is boiled, it can kill the disease-causing microorganisms in the water, so the boiled rainwater is drinkable.

But from the current environmental conditions, it is better not to drink rainwater.

There is often a lot of dust in the air, even in mountainous areas, and in crowded areas, developed transportation and industrial areas, there is more dust in the air, and there are often various pathogenic bacteria, viruses, parasite eggs and other pathogenic microorganisms. When rain falls from the sky, dust in the air can dissolve in the rain; In atmospheric dust, special harmful substances from industrial waste gas and waste residue can also be dissolved in rainwater. And these harmful substances cannot be eliminated by boiling.

Therefore, although the rainwater falling from the sky is convenient to use, it is not suitable for drinking, especially in industrial and mining areas, let alone drinking the stored rainwater.

Rainwater is not drinkable. The main component of rainwater is water (chemical formula H2O), there is a small amount of sulfur dioxide (chemical formula SO2), nitrogen dioxide (chemical formula NO2), usually the pH value of rainwater is about, and the rain with a pH value less than is acid rain, in case of thunderstorms, rainwater will contain a small amount of ozone molecules (caused by lightning), as well as various impurities and floating dust in the air.

Because rainwater contains various pollutants and toxic and harmful chemical elements, it is definitely harmful to the human body.
