Lead Poisoning: Causes, Symptoms, & Treatments Both adults and children get lead poisoning from exposure to lead in their environment. However, the causes of that exposure are typically different. For example, one of the biggest sources of lead exposure in children is paint with lead in it because small children may eat peeling paint or chew on a painted surface.

- Repeated low levels of exposure to lead can alter a child's normal mental and physical growth and result in learning or behavioral problems. If you are pregnant, exposure to high levels of lead can cause miscarriage, premature births, and smaller babies. Exposure can cause decreased mental ability, learning difficulties, and reduced growth in the children exposed to lead during pregnancy.

Lead poisoning and health But it is known that, as lead exposure increases, the range and severity of symptoms and effects also increases. Even blood lead concentrations as low as 5 µg/dl, once thought to be a “safe level”, may result in decreased intelligence in children, behavioural difficulties and learning problems.

Lead poisoning In adults, about 35–40% of inhaled lead dust is deposited in the lungs, and about 95% of that goes into the bloodstream. Of ingested inorganic lead, about 15% is absorbed, but this percentage is higher in children, pregnant women, and people with deficiencies of calcium, zinc, or iron.

Lead exposure and poisoning is especially concerning in infants and children, as it can affect their developing nervous systems and interfere with mental development.ince lead poisoning can cause permanent complications, the best treatment for lead poisoning is prevention. If lead is ingested, bowel irrigation or gastric lavage (stomach pumping) may be considered to help clear the gut. Chelation therapy may be needed to bind and remove lead from the body.

How Does Lead Effect the Nervous System? Once in the bloodstream lead is distributed to three main compartments: blood, soft tissue (kidney, bone marrow, liver, and brain), and mineralized tissue (bones and teeth). Lead effects children and adults in different ways. Low lead levels in children can cause the following side effects: Nervous system and kidney damage. Learning disabilities, attention deficit disorder, and decreased intelligence. Speech, language, and behavior problems. Poor muscle coordination. Decreased muscle and bone growth. Hearing damage.
