摘    要:目的]了解固井水泥粉尘对作业工人健康危害情况。方法]对油田固井水泥加工和使用现场进行劳动卫生学调查,为接尘工人进行内科、眼科、耳鼻喉科体检,并进行高仟伏拍片、心电图、肺功能及血清NO、MDA、SOD、GSH-Px的含量及活性测定。结果]作业场所粉尘浓度严重超标,接尘工人呼吸系统刺激症状、眼结膜炎、眼翼状胬肉、咽喉充血、鼻甲充血的检出率明显高于对照(P<0.01),接尘工人血清NO水平、MDA含量升高,抗氧化酶SOD、GSH-Px下降,与对照组比较,差异均有统计学意义(P<0.01)。结论]固井水泥粉尘对作业工人健康危害严重。

关 键 词:固井水泥粉尘  呼吸系统    鼻咽  肺功能  脂质过氧化

Abstract:Objective] To study on effect of oil well cement dust on the health of workers exposed to dust. Methods] An occupational health investigation was conducted in the workplace including internal medicine,eye and E.N.T.examinations,chest radio-gra-phy, electriocardiography and pulmonary function test,and the concentration of serum NO,MDA and activity of SOD,GSH-Px were measured in the workers exposed to dust. Results] The concentration of dust in the air of workplace was much higher than occupational exposure limit.The incidence rate of irritation symptoms of respiratory system, conjunctivitis, aliform neoplasm, nosepiece congestion and faucitis were higher in workers exposed to dust than those in control workers(P<0.01) . The level of serum MDA and concentration of plasm NO were higher in the exposure group than those in the control group(P<0.01). The levels of SOD and GSH-Px were lower in the exposure group than those in the control group(P<0.01). Pulmonary ventilation function and small airway function decreased in workers exposed to cement dust more significantly than those in workers exposed to other normal Portland cement dust(P<0.01). Conclusion] Oil well cement dust may cause harm to respiratory system,eyes and nasopharynx,strengthen lipid superoxide reation and unbalance between oxidation and counter-oxidation.
Keywords:oil well cement dust  occupational health  respiratory system  eye  nasopharynx  pulmonary function  lipid peroxide
