Health Issues Associated with Lead

The maximum contaminant level goal for lead in drinking water is zero as set by the EPA. Lead is a toxic metal that can accumulate in the body over time and can be harmful to human health even at low exposure levels. Fetuses, infants, and young children are more vulnerable to lead exposure than adults because their bodies can absorb more lead than an adult. Lead exposure can have a damaging impact on a child’s brain and nervous system. Effects of lead exposure in children include:

  • Learning and behavior problems
  • Slowed growth
  • Hearing and speech problems
  • Lower IQ
  • Hyperactivity
  • Anemia


Effects of lead on adults can include:

  • Decreased kidney function
  • Reproductive problems
  • Increased blood pressure


Lead exposure comes from other various sources such as paint, dust, soil, air, and food. Lead and lead compounds have been used in toys, furniture, cosmetics, food/liquid containers, etc. Children are more susceptible to lead exposure as they often put their hands and other objects in their mouths.
