Lead exposure research focuses on studying the various ways in which individuals come into contact with lead, the health effects of lead exposure, and strategies for preventing or mitigating lead exposure. This area of research is important as lead is a toxic metal that can be harmful to human health, particularly in children and pregnant women. Lead exposure can occur through sources such as contaminated water, lead-based paint, and certain occupations. Researchers in this field may investigate the effects of lead exposure on physical and cognitive development, strategies for reducing lead exposure in communities, and interventions to treat or prevent lead poisoning.
