Abstract:
Objective To investigate the effect of occupational lead exposure on blood pressure and provide supportive evidence of health protection on lead-exposed workers.Methods 612 workers (452 lead-exposed workers,160 workers as control) were recruited in the battery factory.The blood lead concentration and blood pressure were detected by occupational health examination and biological monitoring.The relationship of blood lead concentration and blood pressure wasanalyzed.Results The blood lead concentration in the exposed group(249.84±137.74) μg/L was higher than that of the control group (117.25±70.15) μg/L,and the difference was statistically significant(P<0.01).The difference of abnormal blood pressure and diastolic pressure among the exposed and the control group was statistically significant (P<0.05).The abnormal blood pressure rate,systolic pressure rate and diastolic pressure rate in the 400~726 μg/L group was higher than that of the 6~199 μg/L and 200~399 μg/L group,and the difference was statistically significant (P<0.01).Multiple linear regression analysis showed that the influencing factors of the systolic pressure followed by sex,age,length of service and blood lead concentration,diastolic pressure followed by sex,age,smoke and blood lead concentration.Conclusion These findings suggest that long-term occupational lead exposure may result in the increase of blood lead concentration.
