某石油炼制企业汽油作业工人健康状况分析

目的 通过分析某石油炼制企业汽油作业人员的职业健康状况,揭示石油炼制企业职工的健康损害与其接触的职业病危害因素的相关性。 方法 对某石油炼制企业902名汽油作业工人和1 057名非汽油作业工人的职业健康检查结果进行统计学分析。 结果 女性工人中,汽油作业工人白细胞计数减少的异常检出率与非汽油作业工人相比,差异有统计学意义(χ2=4.48,P < 0.05)。经多因素Logistic回归分析,提示汽油接触是女性工人白细胞计数减少的危险因素(OR=2.56,95% CI:1.04~6.29);女性工人中,汽油作业工人的血红蛋白平均含量低于非汽油作业工人,差异有统计学意义(t=-3.18,P < 0.01)。 结论 该企业在目前的生产条件下,汽油接触可能使女性作业工人的白细胞受到损伤,企业应改善作业场所环境,并定期组织接触汽油的人员进行职业健康检查,以保护作业人员的身体健康。

Investigation on health status of workers exposed to gasoline in a petroleum refining company

Objective The health status of employees exposed to gasoline was evaluated to reveal the association between health damage of the workers and the exposed occupational hazards, Methods The data of occupational health examinations of 902 workers exposed to gasoline was compared with that of 1 057 workers without any known occupational exposure in a petroleum refining company. Results The exposed female workers had higher abnormality of white cell counts compared with control workers （χ^2 = 4.48,P 〈 0.05）, and multivariate logistic regression analysis showed that the gasoline exposure was a risk factor for the reduced abnormal white cell counts in the female workers （OR = 2.56,95% CI： 1.04 - 6.29）. Hemoglobin （Hb） in female workers exposed to gasoline was obviously lower than that in control workers （t = - 3.18,P 〈 0.01 ）. Conclusion In the current manufacturing condition, gasoline exposure may cause leukocytopenia among the female employees . In order to protect the health of the workers,company should improve working environment and arrange regular occupational health examination for the gasoline-exposed workers.
