Are batteries harmful to the soil

Waste batteries contain large amounts of heavy metals such as mercury, cadmium, manganese, and lead. When the waste battery is exposed to the sun and rain, the skin layer on the surface will rust, and the harmful components will penetrate into the soil and groundwater. Mercury has strong toxicity. Lead can cause neurological disorders and nephritis. Cadmium can cause kidney damage and bone diseases-osteoporosis, chondrosis and fractures. Once people eat crops processed on contaminated land or drink contaminated water, these toxic heavy metals will enter the human body and slowly deposit, causing great harm to human health. Relevant information shows that a AAA battery rotted in the ground can permanently lose the value of 1 square meter of soil; a button battery can pollute 600 tons of water, which is equivalent to the amount of water a person can drink in a lifetime. Among the several substances that pose the greatest threat to the natural environment, batteries contain mercury, lead, cadmium, etc. If used batteries are mixed with domestic waste and landfilled together, or thrown away, the leaked mercury and heavy metal substances will be destroyed. It penetrates into the soil, pollutes the groundwater, and then enters the fish and crops, destroys the living environment of human beings, and indirectly threatens human health. According to statistics, in Beijing alone, the amount of mercury that enters the natural environment due to waste batteries every year reaches 29.6 tons. Therefore, waste batteries cannot be discarded at will and should be reasonably recycled. Because battery pollution has the characteristics of long cycle and large concealment, its potential harm is quite serious, and improper handling can also cause secondary pollution. When some farmers in a coastal province of my country were recycling lead from lead-acid batteries, they dumped the waste liquid containing lead and sulfuric acid due to improper recycling and treatment, which not only caused lead poisoning, but also prevented local crops from growing.
