Children are the most serious risk because their bodies are small and they are still growing. According to the CDC, lead exposure can affect almost any organ system, but it’s especially dangerous for the central nervous system, including the brain. Blood levels as low as 10 µg/L may slow neurodevelopment in children. In both children and adults, lead can affect memory and cause conditions such as anemia, stomach problems, and high blood pressure.

On the other hand, long-term exposure to cadmium can lead to stomach problems and can damage the kidneys, both in children and adults.
