本文通过调查导弹推进剂作业场所空气中有毒气体的浓度以及在此环境中工作人员的身体状况,并随机抽取生活环境、劳动强度基本一致、而工种不同的人员作对照。结果表明,部分作业场所偏二甲基肼和四氧化二氮超出最高允许浓度,使长期处于低浓度环境下工作的人员出现神经、呼吸、消化系统和眼部不适等不同程度的暂时性症状。未发现有明显的慢性中毒和典型的职业病病例,体检组中枢神经系统阳性症状检出率与对照组有明显差别(P<0.01)、其它症状元明显差别(P>0.05),症状消失的时间与接触推进剂的时间长短呈正比。观察10年以上工龄的干部或志愿兵,当调离工作岗位后,其症状也逐渐消失。证明液体推进剂在人体内不会形成慢性积蓄中毒,是否还存在远期效应有待进一步探讨。
This article by investigating the concentration of toxic gases in the air of the missile propellant workplace and the physical condition of the staff in this environment, and randomly selected living environment, the labor intensity is basically the same, and different types of workers as a control. The results showed that partial dimethyl hydrazine and nitrogen tetroxide exceeded the maximum allowable concentration in some workplaces and caused temporary symptoms of varying degrees such as nerve, respiration, digestive system and eye irritation to those working in long-term low-concentration environment. No obvious chronic poisoning and typical cases of occupational diseases were found. The detection rate of positive symptoms of central nervous system in the test group was significantly different from that of the control group (P <0.01), the other symptoms were significantly different (P> 0.05) And the length of contact propellant is proportional to the length. When the cadres or volunteers who have worked more than 10 years of service observe their symptoms after graduation from their jobs, their symptoms gradually disappear. Proved liquid propellants in the human body will not form a chronic accumulation of poisoning, whether there are still long-term effects to be further explored.
