低浓度苯系物对作业工人的健康影响

目的探讨低浓度苯系物（苯、甲苯、二甲苯）对作业工人健康的影响。方法选择漳州市某光电企业接触苯系物的作业工人186名作为接触组,选择同地区106名饮食行业食品从业人员作为对照组,进行内科常规健康检查和实验室指标检测。用个体采样器采样,用气相色谱法分析测定空气中苯系物浓度。结果职业接触低浓度苯系物的工人高血压和白细胞减少的检出率高于对照组（P〈0.05）。结论长期接触苯系物可能导致血压升高和白细胞减少。

Effect of Benzene Series at Low Concentration on Health of Exposed Workers

Objective]To explore the low concentration of benzene series（benzene,toluene and xylene） on the health of exposed workers.Methods]186 workers exposed to benzene series in an optoelectronic enterprise in Zhangzhou city were selected as the exposed group,and 106 employees in the catering industry in same area were collected as the control group,routine medical health examination and laboratory indexes test were carried out.The personal sampler was applied to sample,and the concentration of benzene series in the air was tested and analyzed by gas chromatography.Results]The detection rate of hypertension and leucopenia of workers exposed to low concentration benzene series was higher than that of the control group（P〈0.05）.Conclusion]Long-term exposure to benzene series may lead to elevation of blood pressure and leucopenia.
