较低浓度二硫化碳对作业男工FM100-HUE辨色能力的影响

为探讨较低浓度二硫化碳 (CS2 )对作业男工FM10 0 -HUE辨色能力的影响 ,采用气相色谱仪检测工人 8小时工作班接触CS2 浓度 ;FM10 0 HUE方法检测 191名CS2 作业男工和 93名对照者的辨色能力。结果显示 ,CS2 暴露组接触CS2 时间加权平均浓度为长丝车间 (14 75± 6 89)mg m3、短丝车间 (16 30± 5 42 )mg m3;常规眼科检查未见特异损伤 ;FM10 0 HUE平均辨色错误得分 (10 6 9)与对照组 (78 3)相比差异有显著性 (P <0 0 5 ) ,对绿色和蓝色区带的辨别能力也显著低于对照组 (P <0 0 5 ) ,且短丝车间表现的影响更为突出。提示较低浓度CS2 对作业男工FM10 0 HUE辨色力有一定的损伤 ,应加强对该类作业工人的健康监护。

Study on FM100-HUE color vision in male workers exposed to lower concentration of carbon disulfide

The effect of CS2 on color vision in workers exposed to CS2 was explored. The color discrimination in 191 exposed and 93 non-exposed male workers was studied by a Farnsworth Munsell 100-HUE (FM100-HUE) test. The results showed that the time weighted average (TWA) concentration of CS2, determined by Japan GC-17A gas chromatography, was (14.75 +/- 6.89) mg/m3 in a long rayon workshop and (16.30 +/- 5.42) mg/m3 in a short rayon workshop. Higher FM100-HUE color vision score was often in the exposed group (106.9) than in the controls (78.3). The discrimination to green and blue zone was also significantly impaired (P < 0.05). It is concluded that the color vision was disturbed in workers exposed to CS2. The workers should be followed by health surveillance.
