煤制甲醇作业人员神经行为功能特征调查

Neurobehavioral Functions of Workers in Coal-Methanol Industry

  • 摘要: 目的 探讨煤制甲醇作业环境对工人神经行为的影响。

    方法 选取某煤化工分公司甲醇厂114 名脱硫泵房作业人员为暴露组,另选该厂管理人员102 人为对照组。测定作业环境中职业危害因素。采用世界卫生组织推荐的神经行为测试组合对研究对象的情感状态和神经行为功能进行测试。

    结果 在作业环境中存在的多种有害因素浓度相对较低,均在国家职业接触限值范围内。在情感状态方面,暴露组“有力- 好动”低于对照组,差异有统计学意义(P <0.05)。在神经行为测试项目中,“简单反应时”中的“最慢反应时”、“手提转捷度”、“数字跨度”以及“视觉保留”测试结果暴露组均低于对照组,差异有统计学意义(P < 0.05)。

    结论 煤制甲醇作业可导致工人神经行为中反应速度、运动速度和记忆力的下降。

     

    Abstract: Objective To assess the neurobehavioral functions of workers engaged in coal-methanol production and potential impact factors.

    Methods A total of 114 workers in the desulfurization pumping station of a coal-methanol plant were selected as the exposure group and 102 staff in the management department of the same plant as the control group. The levels of occupational hazards were determined on selected work sites. Profiles of mood state (POMS) and neurobehavioral functions of all participants were evaluated and analyzed according to the Neurobehavioral Core Test Battery recommended by the World Health Organization.

    Results Twelve chemicals, including methanol, benzene, toluene, xylene and carbon monoxide, were detectable in the selected work sites, but all met the national occupational exposure standards. The standardized score of vigor-activity in the exposure group were statistically lower than that in the control group in POMS (P < 0.05). With regard to neurobehavioral functions, the slowest simple reaction time (SRTE) was significantly prolonged in the exposure group, compared to the control group. The standardized scores of manual dexterity of both predominant and non-predominant hands, backward digital span (DSP), and Benton visual retention (BVR) in the exposure group were significantly lower than those of the control group (P < 0.05).

    Conclusion The working environment of coal-methanol could adversely affect workers' neurobehavioral functions, e.g. declines in reaction speed, movement speed, and memory.
