Zhongshan Daxue xuebao. Yixue kexue ban, 1986 早在1956年就报道了N-二甲基亚硝胺具有致癌作用。从此以后,科学家们对N-亚硝基化合物进行了广泛深入的研究,发现这类化合物有300多种,其中约90％具有致癌活性,这类化合物,在鱼、肉、蛋、奶以及腌渍菜等食品中含可检测出痕迹量,因而促使人们进行更灵敏的检测方法的研究。由于Z-亚硝胺的挥发性、光解性以及氧化还原性,使得建立检测方法的难度很大。迄今为止,还没有一个通用的规范化的方法为大家所接受。一般认为气相色谱—质谱（GC—MS）法,气相色谱—热能分析（GC—TEA）法是最佳方法,但由于这两个方法设备昂贵 ...
