Lead is a naturally occurring heavy metal found in the Earth’s surface. It can affect every organ and system in the human body. Many times, there are no symptoms of lead poisoning and it can build up in our bodies over time, stored in our bones, alongside calcium. It's important to note that no level of lead in a child’s blood is safe, making regular blood testing essential for detecting exposure.
Who is at Risk?
- Children (6 months to 6 years): Lead exposure can harm children’s developing brains, leading to learning problems, lower IQ, growth delays and even seizures or coma.
- Pregnant Women: Lead stored in a mother’s bones can pass to the baby through the placenta or breast milk, potentially leading to miscarriage, premature birth, or slowed fetal growth.
- Adults: Lead exposure can cause high blood pressure, kidney damage and reproductive issues.
Common Sources of Lead
- Paint chips and dust in homes built before 1978
- Lead in soil, water pipes and faucets
- Older painted toys, imported jewelry, certain spices and some home remedies
- Lead-glazed ceramics and crystal
