Lead Poisoning
Category of Toxin
Description of Toxin
Lead has no taste, can not be seen by the naked eye, and has no smell
Form of Toxin
Body System(s) Impacted by Toxin
By: Michelle Tu and Savitri Singh
Pd: 2

Effects of Lead Poisoning
blocks a type of receptor (N-methyl-D-aspartate), affecting brain plasticity (learning)
increases the permeability of the BBB, resulting in edema; the extreme pressure buildup causes irreversible brain damage (brain functioning)
cellularly, lead replaces calcium, readily binding to calmodulin even at low levels, overexerting cellular response when it really shouldn’t (cells of nerves, reproductive system, bone marrow, ect.
Route of Exposure and Symptoms
inhale toxic increments - fumes, dust
ingest - food, water, toys, jewelry, ect
Exposure Limits
It is a very strong poison
When inside the body, it can cause major problems
Storage batteries
Art supplies
Pipes, plumbing
Drinking water
Lead is found in:

naturally occurring bluish-gray metal
soft, durable, easy to find, resistant to corrosion/radiation
skeletal system
reproductive system
abdominal pain, vomiting, constipation
headaches, difficulty concentrating
seizures, coma
fatigue or muscle weakness
Normal: BLL < 25 micrograms/dL
Treatment recommended if :
BLL > 50 micrograms/dL
patient shows symptoms of lead poisoning
Normal: BLL < 10 micrograms/ dL
Treatment/monitoring recommende if :
BLL > 30 micrograms/ dL
Iron – treats anemia caused by lead poisoning
Vitamins and Minerals (Calcium, phosphorus, vitamin D)
decreases BLL concentration
Chelation Therapy (IV/pill)
bind with lead in bloodstream, discharged in urine and bile
stunted growth
impaired hearing
learning disabilities
poorer hand-eye coordination
shorter attention span or reaction
nervous system
Case Study Summary
In Oregon, there was a four year old boy who swallowed a toy that contained lead which remained in his system for three weeks causing him to suffer from lead poisoning. However, when the toy was discovered in the boy's system, a quarter was also found in his system as well. The toy contained 40% lead. In July 2003, he was rushed to the emergency room due to complaints of abdominal pain, vomiting, cramps, diarrhea, and constipation. X-Rays showed the toy and a quarter in the child's system. The boy received chelation therapy to lower the levels of lead in his blood. The incident was accidental. According to the CDC, the boy recovered without any brain damage.
Legislation and Public Policy Enacted due to Lead Poisoning
An OVERVIEW of all you've LEARNED:
Due to lead poisoning:
Senator Charles Schumer made an announcement about the U.S. Department of Housing and Urban Development's Office of Healthy Homes and Lead Hazard Control Program gave $5,125,000 to Western New York to get rid of lead poisoning

These federal funds helped to protect households, families, and children

Many grants were given to other local governments and states to reduce the use of lead-based paints
Legislation and Public Policy (Continued)
Implementation of Title X: Signed into law by President George W. Bush for certification and training of workers for the reduction of the use of lead.
This act is a set of government programs that was a part of the (Title X) The Residential Lead Based Paint Hazard Reduction Act of 1992
1971: The Lead Based Poisoning Prevention Act was passed
Children were blood tested and had elevated levels of lead in their blood, and the cause of this was lead-based paint
Because of this, in 1977, lead-based paint was officially banned from use
