复印室内臭氧污染调查及其对复印工人神经行为的影响

THE DETECTION OF OZONE CONCENTRATION IN COPY-ROOMS AND NEUROBEHAVIORAL EFFECT TO WORKERS

目的 :了解复印场所空气中臭氧浓度及其对人体神经行为功能的影响。方法 :采用公共场所空气中臭氧检测方法 (GBXXXX - 199X)对 9个复印室的室内臭氧浓度进行了检测 ,并应用世界卫生组织推荐使用的神经行为功能核心测验组合 (NCTB)对 2 5名复印作业人员进行了神经行为功能测试。结果 :复印室内臭氧浓度为 (0 .0 15 4± 0 .0 0 2 2 )mg/m3,虽低于国家标准 ,但高于对照室内 (P <0 .0 1)。在NCTB测试中 ,试验组情感状态中的疲倦 -惰性得分显著高于对照组 (P <0 .0 5 ) ,行为功能中数学跨度项目和目标追踪项目中的错误打点数得分与对照组相比有显著差异 (P <0 .0 5 ,P <0 .0 1)。结论 :复印作业可造成室内的臭氧浓度升高 。

Objective:To make clear the ozone concentration in copy workplace and its effect to health of workers.Methods:Indoor ozone concentration was detected in 9 copy-rooms by method of examination of ozone in air of public places (GBXXXX-199X).Meanwhile,the neurobehavioral function of 25 works was checked applying the Neurobehavioral Core Test Battery (NCTB) which is recommended by WHO. Results:The ozone concentration was 0.0154±0.0022mg/m 3,higher than that of control group (P< 0.05 ),although lower than national standard.The mark of tired-lazy in profile of mood states (POMS) of works in copy-rooms was significant higher than that of control(P<0.05).The marks of digit span as well as the wrong number of dotting in aiming of copy-rooms-works were statistically different from that of controls (P<0.05,P<0.01).Conclusions:Copy work could induce the enhance of ozone concentration and long-term work can result in the adverse effect to the neurobehavioral function of the workers.
