Abstract:
Objective:The main purpose of this study was to explore the health effects of occupational exposure to lead exceeded.
Methods:We collected 114 inpatients who exposure to lead, and diagnosed lead toxicity by No. 5 Suzhou People's Hospital from January 2011 to May 2018. Samples were selected according to 1:4 of the lead exceeded group and the control group. The age and gender of the lead exce eded group were matchied, and balanced between the two groups. Lead exceeded group: 84 inpatients occupational exposure to lead, whose blood or urinary lead exceeded. Control group: 336 healthy checkup persons who did not contact with any toxic or hazardous substances.
Results:The diastolic blood pressure of lead exceeded group was significantly higher than control group (P<0.05) . The red blood cell count, hemoglobin, mean red blood cell volume, mean hemoglobin content, mean hemoglobin concentration, the platelet count, and the lymphocyte count levels of lead exceeded group were significantly lower than control group (P<0.05) , while the average platelet volume level of lead exceeded group was significantly higher than control group (P<0.05) . The aspartate aminotransferase, glucose and the urea nitrogen levels of lead exceeded group were significantly higher than control group, while the creatinine of lead exceeded group was significantly lower than control group (P<0.05) . The total protein, albumin, cholesterol and low density lipoprotein levels of lead exceeded group were significantly lower than control group (P<0.05) . The abnormal rate of electrocardiogram and spleen B (24.4%, 8.33%) in lead exceeded group were significantly higher than control group (11.04%, 0.6%) (P<0.05) . The abnormal rate of liver B ultrasound, and gallbladder B ultrasound (23.81%、8.32%) in lead exceeded group were significantly lower than control group (41.32%、21.06%) (P<0.05) .
Conclusion:Occupational exposure to lead exceeded not only has a significant impact on red blood cell related indicators, but also has a certain impact on cardiac function and liver and kidney functions. It is suggested that lead exprsure may have some effect on health of occupational population.
