Old cell phone batteries pollute environment – Yuda

The rechargeable cell phone batteries and other accessories of mobile phones contain some toxic metal elements such as arsenic, mercury, antimony, nickel, tin, gold, lithium, and cobalt. The harm to the environment and human health caused by the waste cell phone batteries mainly comes from the electrolytes and heavy metals contained in the acid and alkali. At present, the old mobile phone batteries are mainly disposed of together with household garbage by landfill, incineration, and composting. Improper disposal of old cell phone batteries will cause great potential harm to the environment and humans.

When used cell phone batteries are discarded in nature or mixed with landfills for landfilling, the outer layer of metal is corroded, and internal heavy metals and acids and alkalis leak out into the soil or water, and then enter the body through various channels. The harmfulness of used batteries to human health is mainly due to a small amount of heavy metal elements. The process of heavy metals entering the soil is: heavy metals → soil → microorganisms → crops → foods → human nervous system → illness. Japan has found that bone ache occurs in certain areas due to long-term consumption of contaminated rice and water containing high amounts of nickel.

If the cell phone and its battery are discarded without any treatment or improper handling, it will seriously pollute the soil and groundwater, and it is easy for humans, especially children, to suffer from cancer and nervous system disorders. If you choose to incinerate, it will cause air pollution and eventually form acid rain into the soil. Waste battery pollution and its disposal are currently one of the most concerned environmental protection issues in the society. Therefore, from the perspective of environmental protection, it is necessary to implement scientific recycling of used mobile phone batteries.
