Lead content was determined in various fractions of red blood cell (RBC) hemolysates from normal controls and from three groups of lead-exposed workers: without toxicity, toxicity associated with high blood lead levels, and toxicity associated with low blood lead levels. The most significant finding was a decrease in the lead bound to a 10,000 molecular weight protein in the group of workers with toxicity at low blood lead levels (43 to 54 μg%). These results suggest that workers who have diminished capacity for synthesizing this low-molecular-weight lead-binding protein are at increased risk for developing lead toxicity at relatively low blood lead levels.
