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

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
• f 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!!!
