Abstract |
Groups of 158 foundry workers and 24 workers from other plants in the same area were studied; 71% of the foundry workers had less than 80µg/100ml lead in blood and no history of elevated concentrations. In the 71% subgroup, central nervous system symptoms (tiredness, sleeplessness, irritability, headache) were reported by 55% of the group and muscle and joint pain by 39%. Zinc protoporphyrin (ZPP) levels were elevated in 71% of cases. Low haemoglobin levels (less than 14g/100ml) were found in more than a third of the workers. While blood urea nitrogen (BUN) and creatinine were mostly in the normal range, there was a correlation between ZPP and both BUN and creatinine. Reduced nerve-conduction velocities were present in 25% of the group; this was not significantly different from findings in a control group. A blood level of 80µg/100ml is an inappropriate biological guide in the prevention of lead disease. |
