作者采用问诊及行为测定方法,对98名粘胶纤维厂男工及91名纺织机械厂男工(作为对照),进行断面流行病学研究。发现接触低浓度二硫化碳(CS_2)可影响人的行为功能,表现为疲劳状态,以及智力、记忆、视感知和操作能力等降低。这些表现存在接触-反应关系,以及测定指标之间的相关性。结果提示:(1)行为测定可以作为某些职业接触流行病学调查的观察指标;(2)粘胶纤维作业工人常年接触10mg/m~3或以上的二硫化碳,可引起某些行为功能的改变;(3)结合其它指标等的阳性发现,我国现行车间空气中CS_2最高容许浓度的标准(10mg/m~3),在条件许可时似可考虑适当降低。
The author used cross-examination and behavioral measurement methods to conduct cross-sectional epidemiological studies on 98 male viscose fiber workers and 91 male textile machine workers (as controls). It was found that exposure to low concentrations of carbon disulfide (CS_2) can affect human behavioral behaviors, manifested as fatigue, and decreased intelligence, memory, visual perception, and operational capabilities. These manifestations have a contact-response relationship and correlations between the measures. The results suggest that: (1) Behavioral measures can be used as observational indicators for some occupational contact epidemiological investigations; (2) Workers exposed to viscose fibers are exposed to carbon disulfide 10 mg/m 3 or more year-round, which can cause changes in some behavioral functions. (3) Combining with other positive indicators, the current CS2 maximum allowable concentration standard (10mg/m~3) in the workshop air in China may be considered to be appropriately reduced when the conditions permit.
