| Abstract | ||
| The lead level in blood and the activity of 6—amino levulinic acid dehydratase (ALAD) was determined in blood samples taken from lead smelter workers and unexposed lead workers. The lead concentrations were higher in the blood of lead workers (17 subjects) than controls (47 subjects) with values of 50 ± 16.86 and 28.98 ± 6.35, respectively. Close negative correlation between PbB and ALAD was found in all subjects. The ALAD activities were lower in smelter t s blood than in the control group by about 42.5%. Determination of ALAD activity in erythrocytes is considered a suitable method for demographic studies of Y exposure to lead. The test is too sensitive for routine follow—up of the degree of lead intoxication in occupationally exposed workers. | ||
