摘　　要：目的:分析2017年宁波市苯接触工人血常规结果,探讨苯暴露对工人血常规影响特征,为制定防护措施提供科学依据。方法:导出2017年宁波市苯接触工人职业健康体检个案卡,使用Excel对资料进行整理,使用SPSS19. 0软件进行统计分析,比较两组及多组间白细胞计数、中性粒细胞计数和血小板计数异常率。结果:2017年宁波市有9 124名苯接触工人参加了职业健康体检,白细胞、中性粒细胞和血小板异常率分别为5. 78%、2. 98%和3. 13%。女性白细胞和中性粒细胞异常率均高于男性(X^2=60. 95、8. 39,P <0. 01),男性血小板异常率高女性(X^2=43. 12,P <0. 01)。50～60岁年龄白细胞异常率组高于其他年龄组(X^2=50. 62,P <0. 01),30岁以下年龄组血小板异常率高于其他年龄组(X^2=90. 55,P <0. 01)。10～14年工龄组血小板异常率高于其他年龄组(X^2=75. 44,P <0. 01)。居民服务、修理和其他服务业体检人群白细胞异常率高于其他行业(X^2=10. 40,P <0. 05),制造业体检人群血小板异常率高于其他行业(X^2=51. 94,P <0. 01),私有企业体检人群白细胞异常率高于其他类型企业(X^2=55. 72,P <0. 01),港澳台企业体检人群血小板异常率高于其他经济类型企业(X^2=638. 06,P <0. 01)。结论:宁波市苯暴露对工人血常规影响较大,对女性及高年龄者影响更加明显,小型私有涉苯企业需要重点监测。Objective To analyze the blood routine results of benzene exposed workers in Ningbo in 2017,and to explore the influence of benzene exposure on workers＇ blood routine,so as to provide scientific basis for making protective measures.Methods The occupational health examination cards of benzene exposed workers in Ningbo in 2017 were obtained. Data were sorted out by Excel and analyzed by SPSS 19. 0. The abnormal rates of white blood cell count,neutrophil count and platelet count between two groups or among multi-group were compared. Results Totally 9 124 benzene exposed workers participated in the occupation health examination in Ningbo in 2017. The abnormal rates of white blood cells,neutrophils and platelets were 5. 78%,2. 98% and 3. 13%,respectively. The abnormal rates of white blood cells and neutrophils in females were higher than in males（X^2= 60. 95,8. 39,P〈0. 01）,while the abnormal rate of platelets in males was higher than in females（χ^2= 43. 12,P〈0. 01）. The abnormal rate of leukocytes among workers in the age group of 50 - 60 years old was higher than other age groups（χ^2= 50. 62,P〈0. 01）,and the abnormal rate of platelets in workers in the age group of 20 - 30 years old was higher than other age groups（χ^2= 90. 55,P〈0. 01）. The abnormal rate of platelets in workers with 10 - 14 working years was higher than others（χ^2= 75. 44,P〈0. 01）. The abnormal rate of leukocytes in workers engaged in resident services,repairs and other services was higher than those working in other industries（χ^2= 10. 40,P〈0. 05）. The abnormal rate of platelets in manufacturing population was higher than those of other industries（χ^2= 51. 94,P〈0. 01）. The abnormal rate of leukocytes in private enterprise workers was higher than workers of other types of enterprises（χ^2= 55. 72,P〈0. 01）. The abnormal rates of platelets in workers working in Hong Kong and Macao enterprises was higher than those of other types of economic enterprises（χ^2= 638. 06,P〈0. 01）. Conclusions Exp
