It's best to find a way to get it back. After all, a well is a relatively closed environment.
In cell phones, circuit boards, especially batteries, contain heavy metals such as copper, mercury, manganese, cadmium, lead and zinc. Your cell phone's casing will slowly corrode, and the heavy metals it contains will gradually leach into the water, causing pollution.
The main characteristic of heavy metal pollution is that they cannot be broken down in nature and can only migrate. That is to say, once the water body is polluted, the water body cannot remove the pollution before its own purification. At the same time, heavy metals are easily accumulated in the living body, which will cause teratogenic or mutagenic effects over time. when they reach a certain quantity, it will eventually have aserious impact on the human body. Besides Minamata disease caused by mercury pollution, others include:
Excessive buildup of manganese in the body can cause neurological dysfunction. , with early manifestations of global dysfunction. In more severe cases, speech is monotonous, expression is dull, emotions are cold, and there are mental symptoms.
Long-term consumption of water contaminated with cadmium can lead to bone pain. Once cadmium enters the human body, it causes osteomalacia, bone deformation, and in severe cases, natural fractures.
Zinc salts, lead, copper and nickel are all very harmful to the human body.
Hello, your idea is good, but it is neither realistic nor feasible. Reason: Well water belongs to groundwater, which is moving, but it is difficult to observe itto the naked eye. Groundwater has a certain flow direction and speed. Groundwater contains water, diving water and water under pressure. Your 20 meter deep water well should be classified as diving. Diving is strongly affected by atmospheric precipitation and ambient air temperature, and it has a waterproof bottom plate and open water surface. It is generally fed by groundwater and atmospheric precipitation coming from upstream. If you fill the well with snow in winter and the temperature rises after spring, the snow and resulting snow-water mixture will have melted and flowed to groundwater and can no longer be retained.
