Chris Cherry, associate professor of civil rights and the environment at the University of Tennessee, Knoxville, found that solar energy, which is highly dependent on lead-acid batteries can potentially free up 2.5 million tons of lead pollution in India and China. Lead poisoning causes damage to the central nervous system, kidneys, cardiovascular and reproductive systems.In children because of high lead levels in blood are observed violation of attention and aggressive behavior. The study also showed that in developing countries, including India, there is a leak large amounts of lead into the environment during mining, smelting, production and processing of solar cells, 22% in India and 33% in China.
Most of the new solar energy systems continue to depend on lead-acid batteries to store energy in these countries. It menas that battery suppliers should work with appropriate control. Otherwise, the use of lead-acid batteries will contribute to environmental pollution and the lead poisoning of workers and children.
