2. Background
 Lead poisoning occurs 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.

6. Treatment and Prevention
 Diagnosis - simple blood test.
 Serum ferritin. This is the most widely used screening
method in determining blood lead levels
 Best prevention for lead poisoning is to avoid further
contact with lead.
 For adults, this usually means making changes at
work or in hobbies.
 For children, it means that parents and guardians
need to find and remove sources of lead in the home.
In most states, the public health department can help
assess the home and identify lead sources.
