摘要
目的了解职业性苯暴露工人外周血白细胞潜在的变化规律。方法抽取某石油化工厂1049名苯暴露工人静脉抗凝血与另一非苯暴露工人841例静脉抗凝血，对白细胞记数按差值为0．5×10^9／L分段对比分析；另在白细胞偏低者休养前后再进行对比分析。结果苯暴露工人外周血白细胞低于4．5×10^9／L的人数比对照组要多（P〈0．05），多集中在（3．5—4．0）×10^9／L之间（P〈0．05）；苯职业病检查白细胞偏低者在休养后白细胞可明显提高。结论对苯作业人员进行职业健康监护时对外周血白细胞在（3．5～4．0）×10^9／L的工人应进行早期干预；其中休养也是很好的防治手段。
Objective To investigate the change of blood white cell of workers exposed to benzene. Methods The white blood count of 1049 workers exposed to benzene and 841 workers without any exposure to benzene were studied. The reference value was taken 0.5×10^9/L. Some workers with low white blood count were followed-up after a short time leaving. Results The exposed worker have lower count of blood white cell, mostly 3.5×10^9/L to 4.0×10^9/L, the percentage of workers with lower count than reference value is higher among exposed workers than non-exposed. The white cell counts increase remarkably among workers with low counts after a short time leaving. Conclusion It means the occupational health surveillance is necessary to find out the workers with lower count of blood white cell and working leave is a good way to help recovery of blood white cell.
