Lead is a toxic element found in the Earth. Unlike minerals and vitamins, lead serves no purpose in our bodies. Lead can be in the air, food, water, and soil. Lead is sometimes found in many products we use, such as glassware, jewelry, toys, and cosmetics.
Lead poisoning is silent. Children often do not look or act sick. When symptoms do appear, they are often confused with other illnesses or conditions. Some symptoms of lead poisoning in children include:
- Irritability
- Fatigue
- Belly pain
- Constipation
- Hearing loss
- Loss of appetite
- Weight loss
- Vomiting
- Trouble concentrating
- Headaches
- Behavioral problems
There is no ‘safe’ level of lead. Even low levels of lead can affect a child’s health.
At low levels, lead can cause behavioral problems. Low levels of lead can affect a child's brain and central nervous system.
At high levels, lead can cause permanent damage to the brain and nervous system. This damage can lead to seizures, loss of muscle control, and coma.
Lead exposure can interrupt a child's progress as they grow. The most common health effects are:
Developmental Delays
Executive Function
Executive function is a set of mental skills that help us learn, work, and manage our lives. These skills include
- planning
- starting and finishing tasks
- controlling our emotion
We learn and use these skills in childhood, and we develop them as we grow. Lead poisoning can slow a child's development of these skills. Children with lead poisoning have a hard time starting and finishing tasks, have trouble paying attention, or may be more prone to emotional outbursts. These effects persist even after a child is lead-free. It does not take a high level of lead for these effects to happen.
Speech and Language
Blood lead levels affect how children learn and process language. Low levels of lead can begin to affect a child’s hearing, which impacts their ability to process language. Decreased hearing can also affect how a child does in school.
Motor Skills
As children grow, they learn to move and walk steadily on their feet. Children with high lead levels are at risk for poor muscle control and trouble with fine-motor actions.
Learning Disabilities
IQ
Lead exposure and IQ are related: as blood lead level increases, a child’s IQ decreases. Even low levels of lead can affect a child’s IQ.
Attention
Children exposed to lead are more likely to be distracted, inattentive, and impulsive.
Sound familiar? These symptoms are shared with attention-deficit disorder (ADHD). A child can be misdiagnosed for ADHD instead of lead poisoning. Ask your provider for a blood lead test.

The information presented in the article emphasizes the pervasive threat of lead, a toxic element found in the Earth. To substantiate the importance of understanding lead exposure, let's delve into the concepts covered in the article:
-
Lead Exposure Sources:
- Lead can be present in the air, food, water, and soil.
- It is found in various consumer products, including glassware, jewelry, toys, and cosmetics.
-
Lead Poisoning Symptoms:
- Lead poisoning is often asymptomatic, and symptoms may be mistaken for other illnesses.
- Children, in particular, may exhibit symptoms such as irritability, fatigue, belly pain, constipation, hearing loss, loss of appetite, weight loss, vomiting, trouble concentrating, headaches, and behavioral problems.
-
No 'Safe' Level of Lead:
- The article stresses that even low levels of lead can adversely affect a child's health.
- At low levels, lead can cause behavioral problems and impact the brain and central nervous system.
-
Health Effects of Lead Exposure:
- Developmental delays and learning disabilities are common consequences.
- Executive function, a set of mental skills crucial for learning and managing life, can be impaired.
- Speech and language processing, motor skills, and attention are also affected.
-
Permanent Damage at High Levels:
- High levels of lead exposure can result in permanent damage to the brain and nervous system.
- This damage may manifest as seizures, loss of muscle control, and coma.
-
Effects on Development:
- Lead exposure can impede a child's progress and development, leading to persistent challenges even after the child is no longer exposed to lead.
-
Executive Function:
- Executive function, encompassing skills like planning, task initiation and completion, and emotion control, can be adversely affected by lead poisoning.
-
Speech and Language:
- Blood lead levels impact a child's ability to learn and process language, potentially affecting academic performance.
-
Motor Skills:
- High lead levels in children may pose risks for poor muscle control and difficulties with fine-motor actions.
-
Learning Disabilities and IQ:
- Lead exposure is linked to decreased IQ, with increasing blood lead levels correlating with a decline in intellectual abilities.
-
Attention Issues:
- Children exposed to lead are more likely to display symptoms resembling attention-deficit disorder (ADHD), potentially leading to misdiagnosis.
Understanding these concepts is crucial for identifying and mitigating the risks associated with lead exposure, especially in vulnerable populations like children. Regular blood lead tests are recommended to detect and address lead poisoning early on.
