摘　　要：对３００名苯作业工人神经行为功能测试结果为，长期高浓度（＞４０ｍｇ／ｍ３）接触组工人的疲劳、困惑、好动等情感状态明显低于对照组（Ｐ＜０．０１）；数字跨度、数字译码等功能状态均低于对照组（Ｐ＜０．０５）；与浓度、工龄的相关分析呈明显的线性相关关系（Ｐ＜０．００１～０．０５）．神经行为功能的改变早于外周血白细胞的改变。作者认为，苯接触者行为功能测试，可作为苯中毒早期监护、评价指标。his article reported 7 neurobehavioral function tests of 300 workers exposed to ben-zene. The results showed that the scores of mood states,i. e. Fatigue, Vigor and Confusion-Bewildermen in workers long exposed to high concentration of bcnzene were significantlylower than those of the control (P<0. 01). The functional states of Digit Span ,Digit Symboland so on in exposed group were lower than those in tbe control (P<0. 05). Correlation anal-ysis of concentration and working agepresented significant negative line correlaitons (P<0. 01～0. 05). The changes of neurobehavioral function were earlier than those of white cellsin peripheral blood. Tbe author believes that neurobehavioral function tests can be used asthe early indicator of supervision and appreciation of benzolism.
