Of 54 milk samples from 54 healthy nursing women analysed for volatile N-nitrosamines, 42 appeared negative. Trace amounts (below the detection limit 0.5 microgram l-1) of N-nitrosodimethylamine were detected in the milk of 10 mothers and two samples contained this compound at 1.1 and 1.2 micrograms 1-1 respectively. Almost all samples investigated contained nitrate (mean 2.9 +/- 2.3 mg1-1 and nitrate reducing microorganisms (mean 4.2 +/- 1.0 log ml-1). The recent finding of N-nitrosodimethylamine in human milk gives evidence of the continuous endogenous formation of N-nitrosamines.
在对54名健康哺乳期妇女的54份乳汁样本进行挥发性N-亚硝胺分析时，42份样本呈阴性。在10名母亲的乳汁中检测到痕量（低于检测限0.5微克/升）的N-亚硝基二甲胺，两份样本中该化合物的含量分别为1.1微克/升和1.2微克/升。几乎所有被调查的样本都含有硝酸盐（平均2.9±2.3毫克/升）和硝酸盐还原微生物（平均4.2±1.0对数/毫升）。近期在人乳中发现N-亚硝基二甲胺证明了N-亚硝胺的持续内源性形成。
