| Abstract |
Groups of lead workers with: long-term presumed moderate exposure and positive (group A) or negative (B) laboratory signs; short-term exposure and positive (C) or negative (D) signs; presumed heavy exposure (E); and a control group (F) showed the following results for total blood lead and the mean proportion of non-precipitable lead respectively: group A, 0.62µmol/l and 48.7%; B, 0.35µmol/l and 44.9%; C, 0.40µmol/l and 48.9%; D, 0.17µmol/l and 24.6%; E, 1.43µmol/l and 44.3%; F, 0.14µmol/l and 18.8%. Thus it appears that when urinary lead is normal (groups D and F), it is excreted largely as precipitable lead even in lead-exposed workers, and that the chief conditions determining excretion of non-precipitable lead are the current or recent degree of lead absorption. The excretory mechanisms and the biological significance of non-precipitable lead are also discussed. |
