Destaillats's team reckon that NNK is produced when nicotine from tobacco smoke reacts with nitrous acid in the air.
Hugo Destaillates的团队猜想，亚硝胺(NNK)是烟草中的尼古丁和空气中的亚硝酸反应生成的。
His team found several chemicals on the inside of the cab of a half-pack-a-day smoker's truck, including a carcinogen called a NNK.
他的团队在每天吸半包烟的出租车车内发现了几种化学物质，包括一种叫做NNK的致癌物。
It releases into your body when you inhale smoke, quickly passes through the liver, gets metabolized and releases NNAL, a byproduct of NNK, into the bloodstream.
当你吸烟时，它会在身体里扩散，迅速穿过肝脏代谢并释放出NNAL，然后产生NNK，进入血液。
As part of the formula, they measured a biological marker, total NNAL, which indicates the amount of exposure to the tobacco-specific lung cancer-causing agent NNK.
作为公式的一部分，他们测定了生物标记物——总nnal含量，它能够反应烟草特异致肺癌成分nnk的含量。
Conclusion: the ns can inhibit NNK induced lung tumorigenesis in mice with a better dose response relationship, and the mechanism may be related to immunoregulation of selenium.
结论：NS对NNK诱发小鼠肺癌有明显防治作用，并有较好的剂量效应关系，其机理可能与硒的免疫调节作用有关。
