【Abstract】 A computer-administered neurobehavioral evaluation "system in Chinese language version (NES-C) and a mood inventory of the Profile of Mood States (POMS) were applied to assess the psychological effects of low level exposure to mercury vapor in a group of 88 workers (19 males and 69 females, with mean age 34.2 years) exposed to mercury vapor (average duration of exposure 10.4 years) . The well-matched group of 70 non-exposed workers was treated as controls.The intensity of current mercury vapor was relatively mild as reflected by the average level of mercury at air of workplace (0.033mg/m3) and in urine (0.025mg/L) . The results indicated that the profile of mood states was posed moving to the negative side in Hg-exposed group and most of the NES-C performances, in particular, the mental arithmetic, two digit search, switching attention, visual choice reaction time and finger tapping were also significantly affected compared with those obtained from controls (P<0.05-0.01) . The present study as well as the previous study on the validation of the system suggest that the NES-C we developed is valid for the neurotoxicity screening among working population exposed to neurotoxic agents.更多还原
