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 ...

PESTICIDE CONCENTRATIONS IN VEGETABLES FROM Fabaceae FAMILY
Scientific Study & Research: Chemistry & Chemical Engineering, Biotechnology, Food Industry, 2011 This study was conducted to assess the concentration levels of nine pesticides in vegetables of the Fabaceae family. For this purpose we used chromatography with electron capture detector (GC-ECD) after the extraction and cleaning.
