Abstract:
Objective To investigate the iufluence of coke oven emissions on workers" blood pressure and electrocardiographic findings,and to provide a basis for the prevention and treatment of cardiovascular diseases.Methods The concentration of coke oven emissions at the bottom,side,and top of coke ovens was determined in a coking plant.A total of 406 coke oven workers were enrolled as exposure group and 201 office staff members were enrolled as control group.Blood pressure and electrocardiographic findings were compared between the two groups,and the multivariate logistic regression analysis was performed to analyze the influencing factors for hypertension and abnormal electrocardiographic findiugs.Results The concentration of coke oven emissions was the highest at the top of coke ovens,followed by the side and bottom of coke ovens,and there was a significant difference between the exposure group and the control group (P＜0.01).The exposure group had significantly higher detection rates of hypertension,abnormal electrocardiographic findings,and abnormal chest X-ray findings than the control group (P＜0.05).The logistic regression analysis showed that high concentration of coke oven emission and age were risk factors for hypertension and abnormal electrocardiographic findings (P＜0.05).The workers exposed to high-concentration coke oven emissions were more likely to experience hypertension and abnormal electrocardiographic findings than those exposed to low-concentration coke oven emissions (OR=1.7 and 1.9).Conclusion Besides lung injury,coke oven emissions also have adverse effects on the cardiovascular system.Therefore,more effective measures are needed to protect the health of coke oven workers.
