甲苯价格低廉,工艺性能好,毒性较苯低,近年来大量地被作为低毒物质取代苯作为橡胶、树脂的溶剂,以及油漆及油墨等的稀释剂。甲苯又是某些化学工业如炸药与染料的重要原料,用途广泛,用量大。因此,甲苯中毒问题逐渐引起人们的注意,对甲苯毒性的研究也有了一些进展。一、临床和毒理(一)神经系统甲苯对神经系统的损害,是当前研究的重点。临床方面,甲苯慢性中毒患者,可出现中枢神经系统症状,脑电图可有改变,也可出现周围神经症状。在低浓度甲苯的 Toluene is low in price, good in process performance and low in toxicity compared with benzene. In recent years, benzene has been widely used as a low-toxic substance to replace benzene as a solvent for rubber and resin, as well as diluent for paint and ink. Toluene is also an important raw material for certain chemical industries such as explosives and dyes. It is widely used in large quantities. Therefore, the problem of toluene poisoning has drawn people’s attention gradually, and some progress has been made in the study of toluene toxicity. First, the clinical and toxicology (A) nervous system Toluene damage to the nervous system, is the focus of current research. Clinical aspects, patients with chronic poisoning of toluene, there may be symptoms of the central nervous system, EEG may have changed, but also peripheral neurological symptoms. At low concentrations of toluene
