Lead is a naturally occurring substance present in many sources in our environment. Past use of lead has led to the widespread presence of lead in the environment, including in soil, food, water and dust inside older homes. Toronto Public Health encourages people to reduce exposure to lead from all sources as much as possible. Lead has been found to cause subtle health effects even at low levels.
