【摘要】：目的了解苯作业工人职业健康状况,探究不同岗位苯作业工人血液指标变化。方法选取青岛市崂山区211名苯作业工人为苯接触组,按岗位不同分为刷胶组和喷涂组,选取53名非接触苯职工为对照,统计分析刷胶组、喷涂组、对照组间血液指标的差异。结果刷胶岗位、喷涂岗位和对照组白细胞异常率分别为19.64%、7.14%和1.13%,差异有统计学意义(P0.05);刷胶岗位、喷涂岗位、对照组红细胞计数分别为4.35×10~(12)、4.50×10~(12)和4.59×10~(12)/L(P0.05),3组血红蛋白分别为126.37、134.55和135.85g/L,刷胶岗位血红蛋白水平显著低于喷涂岗位与对照组(P0.01)。结论青岛市崂山区苯接触岗位工人白细胞异常率较高,红细胞均数及血红蛋白均数下降可能是接苯工人血液指标早期改变的敏感指标。
[Abstract]:Objective to investigate the occupational health status of benzene exposed workers and to explore the changes of blood indexes in benzene exposed workers. Methods 211 workers exposed to benzene in Laoshan District of Qingdao City were selected as benzene exposure group and divided into brush glue group and spray group according to their positions. 53 non-contact benzene workers were selected as control group. The differences of blood indexes among brush glue group, spray group and control group were analyzed statistically. Results the abnormal rates of leukocyte in brush, spray and control groups were 19.64% and 1.13% respectively, the difference was statistically significant (P 0.05). The erythrocyte counts of the control group were 4.35 脳 10 ~ (10) ~ (12) and 4.59 脳 10 ~ (10) ~ (12) / L ~ (0.05), respectively. The hemoglobin levels of the three groups were 126.37134.55 and 135.85 g / L, respectively. The hemoglobin level in the brush gel post was significantly lower than that in the spraying post and the control group (P _ (0.01). Conclusion the abnormal rate of white blood cells in workers exposed to benzene in Laoshan District of Qingdao City is higher than that in workers exposed to benzene. The decrease of mean erythrocyte and hemoglobin may be a sensitive index for the early changes of blood indexes of benzene exposed workers.
