What body system is most affected by lead exposure?

Lead exposure primarily affects the central nervous system, making it the most impacted body system. The neurotoxic effects of lead are particularly severe in young children, whose developing brains and nervous systems are more susceptible to harm. Lead can disrupt the neurotransmission process, leading to cognitive deficits, behavioral issues, and developmental delays.

In adults, lead exposure can also result in neurological symptoms, including memory loss, mood disorders, and decreased cognitive function. Because of these profound effects on neural development and function, lead is classified as a serious environmental hazard affecting brain health.

Other body systems, such as the respiratory, circulatory, and digestive systems, may also experience effects from lead exposure but to a lesser degree or different nature compared to the central nervous system.
