Can used batteries pollute water source land?

Yes. A small button battery can pollute 600 cubic meters of water, which is equivalent to the amount of water a person drinks in a lifetime; A No. 1 battery rotting in the ground can make one square meter of land lose its use value and cause permanent pollution, and its permanence is equal to the power of a nuclear bomb.

At the same time, batteries contain a variety of heavy metals, such as lead, mercury, cadmium, etc. The Minamata disease that shocked China and the rest of the world in Japan in the fifties of the last century was caused by mercury pollution; Lead can cause nervous disorders, nephritis, etc.; Cadmium is very easy to cause chronic poisoning in the human body, and the main diseases are emphysema, osteomalacia, and anemia, which 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. If waste batteries are mixed into domestic garbage and landfilled, over time, the heavy metals may pollute groundwater and soil, and then enter fish and crops, destroy the living environment of human beings, and indirectly threaten human health.

Other manifestations of waste battery hazards: At present, the world's domestic waste treatment is mainly in three ways: sanitary landfill, composting and incineration, and the pollution effect of waste batteries mixed with domestic waste in these three processes is reflected in: landfill:

Heavy metals from used batteries pollute water bodies and soil through percolation. Incineration: Waste batteries corrode equipment at high temperatures, and some heavy metals volatilize in fly ash in incinerators, causing air pollution; Heavy metals accumulate at the bottom of the incinerator, causing pollution to the ash produced.

Composting: Waste batteries have a high content of heavy metals, resulting in a decrease in the quality of compost. Reuse:

Generally, the reverberatory furnace pyrometallurgy method is adopted, although the process is easy to master, but the first rate is only 82%, and the rest of the lead appears in the form of gas and dust, and the sulfur dioxide in the smelting process will enter the air, causing secondary pollution and directly endangering the health of the operator.

According to the survey, waste batteries contain a large amount of heavy metals and electrolyte solutions such as waste acid and waste alkali. If discarded at will, rotten batteries can destroy our water sources and erode the crops and land we depend on, and our living environment is under great threat. If a No. 1 battery rots in the ground, its toxic substances can make one square meter of land useless; Throwing a button battery into the water will cause 600,000 litres of water pollution due to the toxic substances contained in it; Waste batteries contain heavy metals such as cadmium, lead, mercury, nickel, zinc, manganese, etc., among which cadmium, lead, and mercury are substances that are more harmful to the human body.

Although metals such as nickel and zinc are beneficial substances within a certain concentration range, exceeding the limit in the environment will also cause harm to the human body. The heavy metals leached out of waste batteries will cause pollution of rivers, rivers, lakes, seas and other water bodies, endanger the survival of aquatic organisms and the utilization of water resources, and indirectly threaten human health. Electrolyte solutions such as waste acid and waste alkali can pollute the land, acidifying and salinizing the land, which is like a time bomb buried around us.

It will cause no pollution, and there are generally **.

The pollution of used batteries is huge, and after a button battery is discarded in nature, it can pollute 600,000 liters of water, which is equivalent to the water consumption of a person's lifetime. And China consumes 7 billion ...... of such batteries every year

Batteries contain mercury, mercury, a liquid metal. Specific gravity, melting point boiling point 357 .

Mercury evaporates at room temperature, and its vapor is colorless, odorless, and seven times heavier than air. Both mercury and its compounds are highly toxic, especially organic compounds of mercury. Fish are poisoned when they live in milliliters of water containing milligrams of mercury; Ingestion of grams of mercury can lead to death.

There is also cadmium in batteries: cadmium is a very toxic heavy metal, and most of its compounds are also toxic. Japan's "pain" that shocked the world was caused by cadmium pollution. ......

Waste batteries are a big killer that endangers our living environment! A small button battery can pollute 600 cubic meters of water, which is equivalent to the amount of water a person drinks in a lifetime; A No. 1 battery rotting in the ground can make one square meter of land lose its use value and cause permanent pollution.

The threat posed by waste batteries to the environment is still quite large. A single waste battery can pollute three square meters of land.

A No. 1 battery rotting in the ground can swallow up one square meter of land and can cause permanent pollution. A single button battery can pollute 600,000 litres of water, which is equivalent to the amount of water used in a person's lifetime.

Batteries mainly include primary batteries, secondary batteries and automotive batteries. Disposable batteries include button cells, ordinary zinc-manganese dry batteries and alkaline batteries, and primary batteries mostly contain mercury. Secondary batteries mainly refer to rechargeable batteries, which contain the heavy metal cadmium.

Waste automotive batteries contain acid and the heavy metal lead.

Mercury discarded in batteries in nature enters the soil or water source, and then enters the human body through crops, damaging human kidneys. Under the action of microorganisms, inorganic mercury can be converted into methylmercury, which gathers in the body of fish, and after people eat this fish, methylmercury will enter human brain cells, causing serious damage to the human nervous system, and the serious ones will go crazy and die. The famous Japanese Minamata disease is caused by methylmercury.

The cadmium in the battery exudes the fouling cavity and contaminates the land and water, and eventually enters the human body, causing damage to the liver and kidneys, and will also cause bone softness, and in severe cases, bone deformation. The acid and heavy metal lead contained in automobile waste batteries leak into nature, which can cause soil and water pollution, and ultimately cause harm to the human body.

Pollution and Hazards of Waste BatteriesButton Cell Batteries contain mercury, when it is discarded in nature, after the outer metal rusts, mercury will slowly overflow from the battery, enter the soil or enter the groundwater after rain, and then enter the human body through crops, damaging people's internal organs.

Under the action of microorganisms, inorganic mercury can be converted into methylmercury, which accumulates in the body of fish, and after people eat this fish, methylmercury will enter the human brain cells, causing serious damage to the human nervous system, and the serious ones will go crazy and die. Minamata disease in Japan is caused by methylmercury.

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.

Waste batteries contain a variety of toxic and harmful chemicals, which can pollute soil and groundwater if discarded in the natural environment. The main components in waste batteries are heavy metals such as cadmium, lead, and mercury, and chemicals such as sulfuric acid and sodium hydroxide. These substances are released when the battery is opened or damaged inside, and can easily penetrate into the soil and contaminate groundwater, which can have an impact on the environment and human health.

The chemical composition in batteries is dangerous and can have serious consequences to some extent if disposed of haphazardly. For example, lead is a toxic heavy metal that can affect the body's internal organs, such as nerves, liver, and kidneys. If lead is released into the environment, it can cause great harm to the human environment and ecosystems such as mammals.

Cadmium can cause osteoporosis, kidney disease, lung cancer, etc., and can also affect the food chain and even the entire ecological environment. Especially in rural areas and other places, due to people's weak awareness of the use of waste batteries, inadvertently discarding batteries in fields, rivers, etc., will allow various chemical components of waste batteries to penetrate into the soil, which will seriously pollute farmland soil and water sources, and ultimately food, drinking water, and domestic water will be greatly threatened.

In addition, the garbage disposal of batteries also increases the pollution of the environment. If discarded batteries are disposed of incorrectly, whether they are transported to a garbage disposal site or directly stacked in the trash, the chemical components in the waste batteries will be released in a disorderly manner, which will exacerbate environmental pollution. Therefore, the garbage disposal of waste batteries needs to be highly valued and scientifically managed.

To sum up, the random disposal of waste batteries will undoubtedly cause great distress to the environment and human health, so we need to take active measures to strengthen the treatment of waste batteries, effectively reduce the random disposal of waste batteries, and ultimately achieve environmental health and people's safety. <>

The number of years the battery contaminates the land depends on the degree of leakage of the battery and the condition of the material. If the battery is preserved intact in the land, it has little to no impact on the land, and if the battery leaks completely, it will need to be purified for hundreds of years to recover, and sometimes it may even cause permanent contamination of the land.

How to dispose of used batteries:

1. Classified delivery. You can hand over the used batteries at home to the neighborhood office where you are located for disposal.

2. Handle it separately. Different batteries should be handled separately, with dry and rechargeable batteries separated.

3. **Processing. Some waste batteries contain trace amounts of rare metals, which can be utilized.

4. Mercury-free treatment. Batteries at home can be sent to a dedicated disposal site for mercury-free treatment.

5. Landfill disposal. Batteries can be sent to state-designated landfills for landfills.
