lead
Properties of lead.
Lead is a toxic substance that accumulates in the body over time, posing severe risks to human health. In young children under the age of six, whose brains and nervous systems are still developing, lead exposure is particularly dangerous.12
Even small amounts of lead can cause permanent damage and loss of function in affected areas of the brain. The potential complications for children include:2
- Cognitive and developmental issues: Lead exposure is linked to learning disabilities and slowed growth.12
- Sensory impairment: It may result in blindness or deafness.2
- Severe neurological trauma: In extreme cases, exposure can lead to convulsions, coma, and death.2
Because lead is retained by the body, it causes cumulative poisoning, meaning that ongoing exposure significantly increases the risk of irreversible harm. Protecting children from lead sources, such as lead-based paint and contaminated water, is essential for their safety and long-term well-being.12
