2. Background Leadpoisoningoccurs when a person swallows, absorbs, or inhales lead in any form. The result can be damaging to the brain, nerves, and many other parts of the body. Acute lead poisoning, which is somewhat rare, occurs when a relatively large amount of lead is taken into the body over a short period of time. Chronic lead poisoning is a common problem in children that occurs when small amounts of lead are ingested over a longer period. At very high levels, lead poisoning can cause seizures, coma, and even death. 3. Exposureroutes Lead-containing products Occupational exposureWater PaintSoil 4.
