石油沥青工业用途甚广,常温常压下呈固体或半流体状态。生产和使用时多在加热态下进行,加热的石油沥青可放出烟雾,从而造成职业性接触危害和环境污染。本研究用人外周血淋巴细胞非程序DNA合成(UDS)试验和人胚肺成纤维细胞转化试
Petroleum asphalt industry is very versatile, at room temperature and pressure was solid or semi-fluid state. Production and use of more in the heating state, the heated asphalt can emit smoke, resulting in occupational exposure hazards and environmental pollution. In this study, human peripheral blood lymphocyte non-procedural DNA synthesis (UDS) test and human embryo lung fibroblast transformation test
