Lead poisoning can be acute (from a sudden exposure) or chronic (developing over a long time).
Signs and symptoms associated with lead poisoning include learning problems, brain damage, hyperactivity, headache, and hearing loss. Other symptoms and signs can include slow growth, irritability, fatigue, baby colic, memory loss, constipation, vomiting, or nausea.
Causes of lead poisoning
The absorption of lead or any of its salts from the environment into the body can cause lead poisoning. Household paint made before 1978 likely contain lead, and leaded gasoline, certain batteries, water pipes, and pottery glazes also contain lead. Lead is still sometimes also found in water, food, household dust, and soil and can be found in the workplace in some occupations.
