Despite efforts by the United States and the World Health Organization to decrease lead exposure in children, lead poisoning continues to exist in industrialized and developing countries. Any amount of lead can cause toxicity, and even low levels are associated with learning and behavioral problems. While Blood Lead Levels (BLLs) have continued to decrease in industrialized/developed countries, they continue to pose a major health hazard to marginalized populations, where 90% of children with elevated lead levels reside. Population-wide loss of IQ points leads to decreased productivity and loss of earning potential.
