作者根据多年来临床观察、统计分析以及大量动物实验的结果,认为空气中汞蒸气含量的卫生标准应制订一个比容许峰值(0.01mg/m~8)更低的平均最高容许浓度(MAK_D),其主要论据如下。1.各种不同汞作业人员(710名)的临床检查:在平均浓度为0.02～0.03mg/m~8的汞作用下,有35.5%(±2.49)的人出现植物神经衰弱综合征。除记忆力减退、情绪不稳定、睡眠障碍等一般主诉外,尚有不同程度的体征,如震颤,持久性红色皮肤划痕征,甲状腺肿大和机能亢进,吸~(181)碘率增高,嗅觉机能状态改变,肌肉作业能力降低,尿汞增高,血红蛋白含量和红细胞计数偏低,血清间接胆红素略高。这些改变随着接触汞的持续时间延长而加重。部分病例早期
According to many years of clinical observation, statistical analysis and the results of a large number of animal experiments, the author thinks that the hygienic standard of mercury vapor content in air should be set to an average maximum allowable concentration (MAK_D) lower than the allowable peak value (0.01mg / m ~ 8) The main arguments are as follows. 1. Clinical examination of various mercury workers (710): In 35.5% (± 2.49) of persons with autonomic weakness syndrome under the action of mercury with an average concentration of 0.02-0.03 mg / m ~ 8, In addition to memory loss, emotional instability, sleep disorders and other general complaints, there are varying degrees of signs, such as tremor, persistent red skin scratch signs, goiter and hyperfunction, increased absorption of 181 iodine rate, olfactory function Status changes, decreased ability to work in the muscles, increased urinary mercury, hemoglobin content and low red blood cell count, serum indirect bilirubin slightly higher. These changes are exacerbated by the prolonged exposure to mercury. Some cases early
