Lead in Blood • 90% is bound to RBC • 3% is in Serum • Chronic effects arise where the serum levels are elevated (Lead is released to the CNS) • Iron and Calcium sites are the primary entry routes 3

Lead Deposits in the Respiratory Tract • Less than 5 microns- Deep Lung penetration- 95% will be absorbed • 5-120 microns- Cleared by Mucociliary action • 120 microns- Nasal deposits- expelled or swallowed 4

GI Absorption • Most absorbed Lead in the system is through the GI tract • 10% is absorbed • 4-10 times higher Lead absorption with an empty stomach • Increased Calcium in the diet= decreased Lead absorption • Fiber binds Lead and decreases absorption • Skin absorption is minimal 7

Dietary Habits • Increase number of meals per day can decrease Lead uptake • High Fiber • Low Fat • Foods high in Iron and Calcium 8

Lead Excretion • Kidney (Keep in mind that Blood Lead should rapidly decrease during pregnancy due to doubled filtration during pregnancy) • Colon • Minimal biliary excretion, Alcohol use may affect • Whatever is not excreted is stored in bone 9

ZPP • May be affected by inflammatory conditions • Diet low in Zinc • Some meds may affect • Normal value is less than 100mcg/100g • Blood Lead may change drastically but ZPP is slow 10

Medical Conditions to Defer from a High Lead area • Severe Anemia • Liver Damage • IDDM with Renal Compromise • One Kidney or on Dialysis • Current Blood Lead above 30 11

Chelation • Not approved by the FDA for the reduction of Blood Lead • May cause Kidney failure from rapid movement of fluid and particles through the kidney 12

Low Level Health Impacts • All Physicals done at Pb level equivalent to the voluntary reduction value of the time. • No value or benefit seen from review of a sample of this population of workers 13

Value of Baseline Medical Evaluations • Compliance with standard • Only way to protect yourself- how do you understand where you are if you don’t know where you started from? • If you work for Troy Greiss, you can never have enough data!!! 14
