目的了解塑料注塑作业工人健康状况,为注塑作业职业病危害防治提供依据。方法以45家塑料注塑企业的260名注塑作业工人为接触组,220名办公文员、生产管理人员(非注塑接触)为对照组,分别调查其自觉症状,并进行血常规、肝功能等实验室检查、纯音测听检查以及其他内科检查。结果 1接触组头痛(17.3%)、头昏(20.0%)、烦躁不安(28.5%)、记忆力减退(21.5%)、睡眠障碍(12.3%)、咳嗽(27.3%)、咳痰(21.5%)症状检出率以及肺功能减退异常率(6.9%)明显高于对照组;2接触组血清中丙氨酸氨基转移酶(ALT)含量水平以及ALT和谷氨酰转肽酶(GGT)异常率均明显高于对照组;3接触组高频听阈提高(单或双耳)、语频(单或双耳)听阈提高和双耳高频平均听阈>40 d BHL的检出率明显高于对照组;上述差异均有统计学意义(P<0.05或P<0.01)。结论注塑作业工人神经系统、肺功能、肝功能和听觉系统功能均有一定程度的损害,应加强其职业健康保护。
Objective To understand the health status of plastic injection workers and provide the basis for the prevention and control of occupational hazards in plastic injection operations. Methods 260 injection workers in 45 plastic injection molding enterprises were investigated as contact group, 220 office clerks and production managers (non-injection contact) as control group, and their symptoms were investigated separately. The laboratory of blood routine and liver function Check, pure tone audiometry and other medical examinations. Results 1 The headache (17.3%), dizziness (20.0%), restlessness (28.5%), memory loss (21.5%), sleep disturbance (12.3%), cough (27.3% (6.9%) were significantly higher than those in the control group. The level of ALT and ALT and GGT abnormalities Were significantly higher than those of the control group. The detection rate of BHL increased significantly (single or binaural), speech threshold (single or binaural) threshold and peak hearing double-peak frequency> 40 d Group; The above differences were statistically significant (P <0.05 or P <0.01). Conclusion Injection workers have some damage to the nervous system, lung function, liver function and auditory system function, and should strengthen their occupational health protection.
