ABSTRACT

Objective@#To learn about the cardiovascular health effects of workers expose to benzene-toluene-xylene and noise in painting workshop of automobile manufacturing enterprises, and to provide intervention measures and strategies for the health of workers.@*Methods@#The effects of noise exposure, benzene-toluene-xylene exposure and combined exposure on workers' blood pressure and electrocardiogram were analyzed through epidemiological investigation, workplace monitoring and occupational health examination in several automobile enterprises which had carried out occupational hazard factors monitoring and occupational health examination in our hospital from April to October 2017.@*Results@#There were differences in age, sex, working years, smoking, drinking and physical exercise among workers in different exposure groups (P<0.05) . The systolic blood pressure level of workers in benzene-toluene-xylene exposure group and combined exposure group was significantly different comparing with control group (P< 0.05) , After the factors of age and working years were adjusted. The abnormity rate of electrocardiogram in workers were not statistically significant in all groups (P>0.05) .@*Conclusion@#The benzene-toluene-xylene exposure and noise combined with benzene-toluene-xylene exposure in painting workshop of automobile manufacturing enterprises has positive influence on the systolic blood pressure of workers. Regular physical examination and health intervention measures should be strengthened to improve health.
