title: Lead levels in Canadian children: Do we have to review the standard?
abstract: Research indicates that the blood lead levels that were once considered safe can adversely affect the neurodevelopment of children. The purpose of the present article is to review issues surrounding lead exposure in Canadian children, including sources, chronic low levels of exposure, and recommendations for prevention. Information was obtained through searches of MEDLINE and Web of Science using a combination of: "Canada" or "Canadian" plus "child" or "paediatrics" plus "lead" or "lead poisoning" or "blood lead". Centers for Disease Control and Prevention data and American peer-reviewed literature were also used. On-line Health Canada advisories (available since 1995), as well as relevant reports from nongovernmental organization and the media, were reviewed. The present review found that there has been limited surveillance of blood lead levels of Canadian children and, mainly, among high-risk groups. Harmful health effects may occur below the current standards and the threat of lead in consumer products remains. The current regulation seems to be inadequate to protect Canadian children.
