What is Lead Lead is an elemental metal Forms 0.06% of the earths crust Cannot be destroyed, only smaller Should not be in our bodies
Why was Lead Used Prevents Corrosion Kills mold and mildew Malleable Strong Blocks Radiation Blocks Sound Drying Agent
Problems Its a chronic and acute poison Contamination
Where is Lead Found? Quality Paint
Military uses Bridges and Steel Structures
Residences Interior Exterior Banned in 1978 Schools in 1984
Lead is Found in Gasoline Used over a period of 50 years 93% reduction from
Lead Is Found In…. Industrial Releases Soil Food Drinking Water Occupational Exposure
Heart and Blood System High blood pressure Increased risk of heart attack and stroke Anemia
Kidneys Filter the blood Not detectable Kidney failure
Central Nervous System Most affected Permanent Brain damage Damage to nerves
Bone Tissue Body Burden Released when the body is under stress Pregnancy Menopause Serious Illness
Reproductive Systems Male System –Impotency –Lack of drive –Damage to sperm –Infertility Female System –Infertility –Birth defects –Miscarriage –Pregnancy
Children Proportion to body weight and size Developmental effects More hand-to mouth contact More absorption of lead
Lead Bans/Phase-Out Late 20 th Century Residential paint (1978) Solder and pipes for drinking water Solder in food cans Gasoline Huge improvements in air quality in last 50 years but DETERIORATING LEAD-BASED PAINT still a major source of lead pollution today
