There is information on acid rain, but also on the hazards of batteries

Acid rain is acidic precipitation caused by air pollution, and it is generally considered that the acidity of atmospheric precipitation and carbon dioxide gas is the natural acidity of precipitation, and it is used as a standard for judging whether it is acidic, and when the pH of precipitation is lower, precipitation is called acid rain.

Why does precipitation turn sour? This is mainly the result of the absorption of atmospheric pollutants by the clouds in the air and the constant reaction within the raindrops to form acidic substances; Acid rain is extremely harmful to the environment, known as the "killer" from the air, it not only causes the death of forests, affects the yield and death of crops and freshwater aquatic organisms, but also corrodes buildings and all facilities exposed to the air and historical relics and monuments, and even endangers human health and endangers the ecological balance of the city.

At present, the area polluted by acid rain in China accounts for about 30% of the country's land area, and is developing at an alarming rate in some areas, with the direct loss of agriculture and forests in Sichuan, Guizhou, and Guangzhou, and Guangzhou, and four provinces and regions alone amounting to 1.8 billion yuan per year; The main cause of acid rain in China is a large number of sulfur dioxide pollutants emitted in the process of coal-based energy consumption. Therefore, in order to control acid rain pollution, the total amount of sulfur dioxide emissions must be controlled first.

Relevant information shows that a No. 1 battery rotting in the ground can make 1 square meter of soil permanently lose its use value; One coin cell battery can contaminate 600 tons of water, which is equivalent to the amount of water a person drinks in a lifetime. In the most threatening to the natural environment of several substances, batteries contain mercury, lead, cadmium and other kinds, if the waste battery is mixed with domestic garbage landfill, or discarded, the leached mercury and heavy metal substances will penetrate into the soil, pollute groundwater, and then enter the fish, crops, damage the living environment of human beings, and indirectly threaten human health.

Once the human body absorbs these heavy metals, what diseases will occur? According to relevant experts, mercury is a very toxic heavy metal, which has a great destructive power on the central nervous system of the human body, and the Minamata disease that occurred in Japan in the 50s of the last century was caused by mercury pollution. At present, the mercury content of mercury-containing alkaline dry batteries produced in China is 1 5, and the mercury content of neutral dry batteries is 0 025, and the mercury consumption of battery production in China is as much as dozens of tons every year.

Cadmium is very easy to cause chronic poisoning in the human body, and the main diseases are emphysema, osteomalacia, anemia, and it is likely to paralyze the human body. Lead is the most difficult to excrete after entering the human body, and it interferes with kidney function and reproductive function.

Experts believe that due to the characteristics of battery pollution with long cycle and large concealment, its potential harm is quite serious, and improper treatment will also cause secondary pollution. According to Dr. Yang Yifu, some farmers in a coastal province in China poured out the waste liquid containing lead and sulfuric acid because of improper treatment of the lead in the lead-acid battery, which not only caused lead poisoning, but also made local crops unable to grow.

Waste batteries contain a variety of chemicals, some also contain mercury, silver, cadmium and other heavy metals, waste batteries in nature mercury, cadmium, lead and other heavy metals will spill or leak into nature, can cause soil and water pollution, and ultimately cause harm to people
