What are the adverse health outcomes of lead exposure?

Exposure to high levels of lead may cause anemia, weakness, and kidney and brain damage. Very high lead exposure can cause death. Lead can cross the placental barrier, which means pregnant women who are exposed to lead also expose their unborn child. Lead can damage a developing baby’s nervous system.

What are critical effects of exposure to lead?

Long-time exposure to lead has been reported to cause anaemia, along with an increase in blood pressure, and that mainly in old and middle aged people. Severe damage to the brain and kidneys, both in adults and children, were found to be linked to exposure to heavy lead levels resulting in death.

What is an acute effect of lead exposure?

Health effects at these very high BLLs can range from acute effects such as convulsions, coma, and in some cases, death, to more chronic conditions such as anemia, peripheral neuropathy, interstitial kidney fibrosis, and severe abdominal cramping.

What does lead do to the brain?

Lead exposure can have serious consequences for the health of children. At high levels of exposure lead attacks the brain and central nervous system, causing coma, convulsions and even death. Children who survive severe lead poisoning may be left with intellectual disability and behavioural disorders.

Does lead affect the adult brain?

Adults who suffered childhood lead exposure were shown to have decreased brain volume, mainly in the prefrontal cortex, affecting fine motor control and executive functioning skills.

What does lead do to your brain?

How does lead affect the nervous system?

Lead poisoning can cause peripheral nerve damage: this can cause muscle weakness and problems with the sense of touch. When researchers examine these damaged nerves, they find that the myelin insulation is often gone and the axons are destroyed. These changes prevent nerves from transmitting messages properly.

Is lead poisoning reversible in adults?

Is There a Treatment for Lead Poisoning? There is no way of reversing damage done by lead poisoning, which is why pediatricians emphasize prevention. But a diet high in calcium, iron and vitamin C can help the body absorb less lead.

Is lead exposure reversible?

There is no way of reversing damage done by lead poisoning, which is why pediatricians emphasize prevention. But a diet high in calcium, iron and vitamin C can help the body absorb less lead.

What part of the body does lead affect the most?

The greatest risk is to brain development, where irreversible damage can occur. Higher levels can damage the kidneys and nervous system in both children and adults. Very high lead levels may cause seizures, unconsciousness and death.

What are the health effects of lead exposure?

Recent evidence has revealed other important health effects of lead exposure, such as hypertension and other cardiovascular outcomes // and renal disease //. Chronic lead exposure in adults can also lead to decreased fertility, cataracts, nerve disorders, muscle and joint pain, and memory or concentration problems.

Is there a safe level of lead exposure in children?

No safe level of lead exposure in children has been identified. Exposure to lead can seriously harm a child’s health and cause well-documented adverse effects such as: Damage to the brain and nervous system

What happens if you are exposed to lead during pregnancy?

Health Problems Caused by Lead. Very high lead exposure can cause death. Lead can cross the placental barrier, which means pregnant women who are exposed to lead also expose their unborn child. Lead can damage a developing baby’s nervous system. Even low-level lead exposures in developing babies have been found to affect behavior and intelligence.

How can we continue to reduce lead exposure?

Achieving continued meaningful reductions in lead exposure requires a long-term concerted effort that addresses all current and historic sources. This document provides a science-based public health approach and a coordinated strategy for continuing our progress to reduce lead exposures and protect public health.
