Lead is a toxic heavy metal that is ubiquitous in the environment due to its long history of use in a variety of industrial applications. Its unique properties make it useful for a wide range of products, including batteries, ammunition, electronics, plumbing, and construction materials. However, lead exposure is a serious public health concern, particularly for children who are more vulnerable to its toxic effects. Even low levels of lead exposure can cause irreversible damage to the nervous system, resulting in developmental delays, behavioral problems, and cognitive deficits. Lead poisoning can occur through various sources, such as contaminated water, soil, food, or dust, as well as through occupational or recreational activities. Prevention efforts include reducing lead exposure in housing, soil, and consumer products, as well as promoting safe use and handling of lead in industrial and commercial settings.
