Some people believe that the rain is transparent and crystalline, the snow is white and immaculate, 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.

Rainwater is not clean and cannot be drunk directly.

I don't think the rain is very clean.

The rain is very dirty and can't be drunk at all.

Scientifically speaking, boiling water kills pathogenic microorganisms in the water, so boiled rainwater is drinkable. But according to the current environmental conditions, do not drink rainwater. When rain falls from the sky, harmful substances such as dust in the air dissolve in the rainwater.
Rainwater is transparent and clean, but it actually contains a lot of bacteria and dust that we can't see with the naked eye, and when the rain falls on the ground, these bacterial dust also fall with the raindrops. Moreover, the water vapor in the air must adhere to the nodules in order to form water droplets, and the nodules are generally acted by some dust substances, so the rain itself is not clean.

Rainwater is not drinkable.
Scientifically speaking, boiling water kills pathogenic microorganisms in the water, so 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.

Analysis: The rainwater is not clean and cannot be drunk directly. Because oceans, lakes, rivers, wetlands, etc., are exposed to sunlight, the water in them evaporates, and it becomes water vapor, which is scattered in the air. >>>More
Rain is the earth's water cycle, and it may contain some minerals, which are good for the human body, but it also contains bacteria, which is more harmful than good. >>>More
The subject is asking if you can use pesticides when it rains? If this is the question, then the answer is that it is better not to fight, whether it is raining or it raining after playing. Or after the rain, it will greatly dilute the medicinal properties, reduce the effect, or even have no effect.
