都市环境电磁辐射对青少年神经行为的影响

目的　探讨都市环境各频段电磁波同时混合存在于一个环境内对青少年神经行为的影响。方法　利用WHO推荐的神经毒理学行为试验—神经行为核心测试组合进行检测。结果　高背景环境电磁射组青少年提转捷度、数字译码得分明显高于低背景环境电磁辐射组 (P均 <0 0 5 ) ,而其 (16～ 18岁 )目标追踪试验的总点数和正确点数均明显低于低背景环境电磁辐射组 (P均 <0 0 5 )。结论　大都市现有环境电磁辐射对青少年的手工操作敏感度及眼手协调能力、视觉感知、记忆、模拟学习能力无不良影响 ,但对青少年 (特别是 16～ 18岁的女性 )心理运动稳定性、手部运动速度可能有一定的影响

Effects of environmental electromagnetic radition on teenager's neurobehavior in metropolis

Objective To investigate the effects of the frequency ele ctromagnetic waves coexisted in same environment on teenagers' neurobehavior.Methods Neurotoxicological behavioral test-Neurobehaviora l Core Test Battle(NCTB) was used for neurobehavioral Measurement.Results Teenagers scores of Santa Ana Manual Dexterity Te st and Digit Symbol in high electromagneitc radiation environment are significan tly higher than that in low electromagnetic radiation environment(P<0.05), and the score of Pursuit Aiming Test in Teenagers(16-18 years old) in high elect romagnetic radiation environment is statistically decreased(P<0.05).Conclusion The environmental electromagnetic radiation no wadays in metropolis has no harmful effect on teenagers' manual dexterity,eye-ha nd coordination ability,vision sensaion,memory,modeling learning ability.And may have harmful effect to teenagers(especially 16-18 years old female) psychologic al stability and hand-movement speed.
