中国视屏显示终端职业危害研究现况

The present situation of VDT occupational hazard in China

调查发现视屏显示终端操作者主诉有神经衰弱、易感冒、眼和肌肉骨骼不适。客观呈现眼视力下降，颈肩腕肌肉压痛。生殖系统调查有月经异常和先兆流产、自发性流产率增高。研究揭示，视屏显示终端室内外温差大，空气阴离子减少，臭氧很少，固定式的桌椅和不良的坐姿等是影响视屏显示终端操作者健康的主要因素。符合卫生标准的环境和工效学原则的规范化操作，可保护视屏显示终端操作者的健康。工间休息能使视力恢复，不良的健康反应得以消除。

We investigated VDT operators. They complained of neurasthenia, catch cold easily and eyes, muscle and skeleton symptoms. In objective, their sight declines, their muscle in neck, shoulder and wrist feels pain. The rate of mense abnormality, threatened abortion, spontanoous abortion increases.The study reveals that the main factor affecting VDT operator's health are fixed desk and chair,adverse postrue, the temperature various greatly between inner and outer room, anion in air decrease,ozone is less. The standardization operation which is accord with hygiene's environment and ergon omics principals can protect VDT operator's health, work-break can recover their sight and elimininate unhealthy effects.
