甲苯的主要健康危害是麻醉和神经毒作用。高浓度短时间的甲苯蒸气职业性接触可引起头晕、嗜睡和神志不清。长期职业性接触可使中枢神经系统受损。尚无令人信服的证据说明甲苯对其他器官的损害。
The main health hazards of toluene are narcotic and neurotoxic effects. Occupational exposure to toluene vapor at high concentrations and for short periods can cause dizziness, lethargy and confusion. Long-term occupational exposure can damage the central nervous system. There is no convincing evidence of toluene damage to other organs.
