Why do batteries harm the land? What is the harm of the battery buried in the soil

A No. 1 or No. 5 battery rotting in the soil can make 1 square meter of land lose its use value forever. One button battery can contaminate 600 tons, 600,000 liters, and 600 cubic meters of water.

Because the battery contains heavy metals, such as mercury, these heavy metals can pollute large areas of land even if they are only a little bit, and the battery is even more terrifying when thrown into the water.

Batteries contain a lot of heavy metals, such as zinc, lead, cadmium, mercury, manganese... It will cause great harm to the earth. And batteries will rot when they are discarded as garbage.

The metal inside will penetrate the earth and groundwater, thus poisoning a large number of animals and plants without knowing it, resulting in death. And the land cannot be cultivated, and even the plants cannot survive...

This is because the electrolyte inside the battery, such as mercury, deteriorates the soil after it decays.

It contains harmful substances such as mercury.

If batteries are discarded in the soil, heavy metals such as lead, mercury, and cadmium can contaminate the soil, and rotten batteries can also contaminate nearby water sources. Severe heavy metal poisoning can occur if people eat food grown on contaminated soil or drink contaminated water. A rotten No. 1 battery, the heavy metals in which can make a square meter of soil incapable of planting, a rotten button battery.

It will pollute 600,000 litres of water.

Polluting the land. Waste batteries contain a large amount of heavy metals such as mercury, cadmium, manganese, lead, etc. When the surface cortex of the waste battery is corroded in the sun and rain, the components in it will penetrate into the soil and groundwater, and once people eat the crops produced by the polluted land or drink the polluted water, these toxic heavy metals will enter the human body and slowly deposit down, causing a great threat to human health.

It has been measured that a No. 1 battery rotting in the soil can make one square meter of land lose its use value, and a button battery can pollute 600,000 liters of water, which is equivalent to a person's lifetime drinking water. Nearly 5 billion people in the world to lose a battery per person every month, a year to accumulate 60 billion batteries, the destructive power to the earth can be said to be great, the consequences of its harm to human health are even more unimaginable, according to statistics, only Beijing every year due to waste batteries and into the natural environment of mercury actually reached tons.

Therefore, used batteries cannot be discarded at will.

A battery is a device that converts chemical energy into electrical energy in a cup, tank, or other container or composite container that contains an electrolyte solution and metal electrodes to generate an electric current. It has a positive electrode and a negative electrode.

With the advancement of technology, batteries generally refer to small devices that can generate electrical energy. Such as solar cells. The performance parameters of the battery mainly include electromotive force, capacity, specific energy and resistance.

Using the battery as energy, you can get a stable voltage, stable current, long-term stable power supply, little influence from the outside world, and the battery structure is simple, easy to carry, simple and easy to charge and discharge, not affected by the outside climate and temperature, stable and reliable performance, and plays a great role in all aspects of modern social life.

1. Waste batteries contain a large amount of heavy metals such as mercury, cadmium, manganese, lead, etc. When the waste battery is exposed to the sun and rain, the skin layer on the surface will be corroded, and the harmful components in it will penetrate into the soil and groundwater.

2. Mercury has strong toxicity, and lead can cause nervous disorders, nephritis, etc.; Cadmium mainly causes kidney damage as well as bone diseases such as osteoporosis, osteomalacia and fractures.

3. A No. 1 battery rots in the ground, which 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. Among the substances that pose the greatest threat to the natural environment, batteries contain mercury, lead, cadmium and more.

4. If the waste battery is mixed with domestic garbage and landfilled, or discarded, the leached mercury and heavy metal substances will penetrate into the soil, pollute the groundwater, and then enter the fish and crops, destroy the living environment of human beings, and indirectly threaten human health. According to statistics, only in Beijing every year due to waste batteries into the natural environment of mercury reached tons, so waste batteries can not be discarded at will should be reasonable.

Mainly mercury hazards:

Mercury has a low volatilization temperature and is a highly toxic heavy metal. In many places, the soil also contains trace amounts of mercury, and the mercury (vapor) released into the air during mercury mining, refining, and processing of mercury-containing products can have a significant impact on the health of operators if the containment measures are not complete.

Although mercury is present in batteries, it is present in very small amounts due to its additive. Even high-mercury batteries generally contain less than 1/1000th of the weight of the battery. The annual mercury consumption of China's battery industry is roughly equivalent to the amount of mercury in the wastewater discharged by a mercury-based polyvinyl chloride, or mercury-based alchemy, or high-mercury lead-zinc mining and dressing enterprise.

Due to the large consumption area of the battery, the impact on the environment of the mercury-containing waste battery after entering the domestic waste treatment system is much smaller than that caused by the discharge of mercury-containing wastewater by the above-mentioned chemical enterprise, and the battery uses stainless steel or carbon steel as the outer skin, which effectively prevents the leakage of mercury.

Therefore, waste batteries are scattered and discarded in domestic garbage, and the harm is negligible, and it is objectively impossible to cause harm such as Minamata disease. Minamata disease in Japan is caused by the accumulation of mercury in downstream water systems by chemical companies that have been discharging large amounts of mercury-containing wastewater into a river for decades.
