What are the hazards to the environment caused by improper disposal of waste batteries

Waste batteries contain toxic substances such as mercury, cadmium, lead, zinc and other heavy metals; if mercury is poisoned, it will damage the nervous system and the mortality rate is as high as 40%; the important hazard of cadmium is nephrotoxicity, which will continue to cause pain (causing osteoporosis, osteomalacia) It is also a carcinogen; human consumption of lead-containing food will affect the synthesis of enzymes and normal heme, and affect the nervous system; the metal shell of waste batteries will be corroded and perforated within one month after landfill treatment. Harmful substances in waste batteries will enter the soil and water bodies, causing pollution to the environment. According to the inspection of environmental protection experts, if 6 tons of domestic waste are mixed with mercury-containing batteries, the concentration of mercury in the soil after the landfill will exceed the safety standard; if the waste batteries and domestic waste are mixed into the incineration plant, the mercury, cadmium and other metals in the It will evaporate into the atmosphere at high temperature, pollute the atmosphere and affect human health. The mercury, cadmium, and lead in the battery will not leak out during normal use; lead-acid batteries are not polluted during use, but lead is a stable, non-degradable pollutant during the recycling process. It can not only enter the human body directly through air and water, but also accumulate in the human body through long-term consumption of contaminated animals and plants. If it is not used externally, it cannot be excreted through natural metabolism, resulting in human intelligence decline, low learning and work performance, mental disorders and other chronic poisoning symptoms, especially affecting the baby's nerve, hematopoietic system and intellectual development. Cadmium is a very toxic heavy metal substance. Nickel-cadmium batteries will not leak during use unless the battery encounters force majeure.
