Lead is famously toxic, especially for children. No amount of lead exposure is safe. It can damage almost every organ and system in the body; it lowers IQ; and it's strongly associated with learning and behavior problems. Many of lead's effects can be irreversible. For all these reasons, reducing exposure to lead, particularly during early childhood, is of enormous public health significance. To this end, public health agencies have an important role to play in designing and implementing effective policies and programs.
