目的探讨石油沥青烟对作业人员的危害情况。方法选择某市电器厂石油沥青工122人为观察组,同厂行政后勤人员149人为对照组,进行肝功能及血常规检查。结果肝功能方面,观察组ALT异常率为19.8%,明显高于对照组(9.4%),2组间的差异有统计学意义(P<0.05);而AST、TP,ALB、CLO、A/G的异常率,2组间的差异均无统计学意义(P>0.05)。血常规指标方面,观察组WBC、RBC、PLT水平与对照组间差异有统计学意义(P<0.01),其中观察组WBC、PLT的异常率明显高于对照组,观察组RBC的异常率明显低于对照组,差异有统计学意义(P<0.01或P<0.05);Hb在2组间的差异无统计学意义(P>0.05)。不同专业工龄间的各异常指标差异无统计学意义(P>0.05)。结论沥青烟可能对作业人员肝功能及血常规指标的改变有一定影响。
Objective To explore the hazards of petroleum asphalt smoke to workers. Methods One hundred and twenty-two petroleum asphalts workers in a city electrical factory were selected as the observation group and 149 administrative staff of the same factory as the control group for liver function tests and blood tests. Results In liver function, the abnormal ALT rate in observation group was 19.8%, which was significantly higher than that in control group (9.4%). The difference between two groups was statistically significant (P <0.05) G abnormal rate, no significant difference between the two groups (P> 0.05). In terms of blood indexes, the WBC, RBC and PLT levels in the observation group were significantly different from those in the control group (P <0.01). The abnormal rates of WBC and PLT in the observation group were significantly higher than those in the control group, and the abnormal rate of RBC in the observation group was obvious The difference was statistically significant (P <0.01 or P <0.05). There was no significant difference in Hb between the two groups (P> 0.05). There were no significant differences in the abnormal indexes among different professional and senior staffs (P> 0.05). Conclusion Asphalt smoke may affect the liver function and blood routine indexes of operators.
