【摘要】 目的　探讨居室装饰油漆工外周血淋巴细胞染色体畸变率和微核发生率的变化。方法　应用气相色谱法测定工作场所苯等有机溶剂浓度 ,按常规方法检测外周血淋巴细胞染色体畸变率和微核发生率。结果　在工作场所空气中苯等有机溶剂浓度超标 2～ 2 5倍 ,接触组工人外周血淋巴细胞微核发生率为 7 12‰ ,对照组为 1 5 6‰ ;染色体畸变率接触组为 2 62 % ,对照组为 0 62 % ,接触组均显著高于对照组 (P <0 0 1)。结论　油漆工作业场所苯等有机溶剂浓度严重超标 ,致使作业工人外周血淋巴细胞染色体畸变率和微核发生率升高。更多还原

【Abstract】 Objective To study the possibility and degree of chromosome aberration and micronucleus rates of painting in indoor decoration. Methods 30 workers who had been working in indoor painting for long time were randomly selected from building labour market, half for men and half for women. Concentrations of benzene etc. in workplaces were measured. Chromosome aberration and micronucleus rates of lymphocyte in periphery blood were tested by regular method. Results Concentrations of benzene etc. in workplaces air were 2～25 times over hygienic standard. Micronucleus rates of lymphocyte in periphery blood were 7.12‰ in exposure groups and 1.56‰ in control; chromosome aberration rate were 2.62% in exposure groups and 0.62% in control. The two indices in exposure group were higher than those in control ( P <0.01). Conclusion Concentrations of benzene etc. in workplaces air seriously exceeded hygienic standard in indoor decoration. The increase of chromosome aberration and micronucleus rates of lymphocyte in periphery blood were observed.更多还原
