Abstract
Lead is a dense metal that is resistant to corrosion. Lead has various uses that have been in place since 3500 BCE such as plumbing, cosmetics, jewellery, and batteries. Today, however, lead remains a public health hazard, especially for children between the ages of 6 months to 6 years old. Children who live in lower socioeconomic regions or have emigrated to the United States (US) are considered to be at a greater risk from the negative effects of lead exposure. Lead exposure has an effect on neurological, cognitive and physical development in children. Primary prevention education is identified as the most important aspect needed to lower blood lead levels. School nurses can play an important role in educating the school community, parents, and children on the effects of lead exposure on children. This literature review focuses on the various ways lead exposure can occur, how it may affect a child's cognition and the leadership role of school nurses in the primary prevention of lead exposure among school age children.
