苯并(a)芘[B(a)P]是一种致癌性多环芳烃,在环境中广泛存在。环境中的B(a)P是前致癌物,进入体内后需经代谢激活,才能转变为具有生物学活性的终致癌物。已有实验证明,B(a)P能诱发许多实验动物肿瘤。流行病学调查显示B
Benzo (a) pyrene [B (a) P] is a carcinogenic polycyclic aromatic hydrocarbon widely present in the environment. B (a) P in the environment is a procarcinogen and can be converted to a biologically active, final carcinogen after it enters the body and is metabolically activated. It has been experimentally demonstrated that B (a) P can induce many experimental animal tumors. Epidemiological survey shows B.
