When batteries are discarded, they pose a significant threat to the environment through air, water, and soil pollution. One of the ways batteries contribute to air pollution is through the release of greenhouse gas emissions during their decomposition in landfills, which is caused by a photochemical reaction. Additionally, batteries contain harmful substances such as acids, chemicals, and metals like lead, manganese, nickel, mercury, and lithium. When these substances leach into the soil, they can result in heavy metal poisoning, posing a risk to flora and fauna. Furthermore, these pollutants can find their way into water bodies, accumulating in plants and animals, and posing a health risk to both animals, including humans, who consume them. The consumption of contaminated plants and animals can lead to serious diseases like cancer, putting the health of ecosystems and communities at risk.
