浩瀚水质 亚硝胺类化合物的测定 气相色谱仪GC7990

Nitrosamines are nitroso compounds, including nitrosamines and nitrite amine nitrite and amine is two kinds, especially for a large class of chemical synthesis of secondary amine, contain N nitroso groups. Most can lead to human poisoning and even a strong carcinogenic, causing great harm to human health. One of the reasons for the formation of esophageal cancer is it - nitrosamines.

一般人以为，只有常吃烧烤、腌渍食物的人才较容易罹患食道癌，其实平时家中常见的几样料理用品或佐料，例如味噌、豆豉、泡菜等，也都有诱发食道癌的因子，因为这些食物中，含有过量的亚硝胺类化合物，而亚硝胺化合物是高度的致食道癌物质。以下是常吃的几种含亚硝胺类食品，平日***好不要过量食用，每天的食用量以不超过自己中指的体积为宜。

Most people think that only eat barbecue, pickled food people are more predisposed to esophageal cancer, in fact, usually at home, several kind of food products or ingredients, such as miso, fermented black bean, pickled cabbage, also have the inducing factor of esophageal cancer, because these foods contain nitrosamines, excess, and sub nitramine is highly induced by esophageal cancer material. Here are some eat food containing nitrosamines, usually best not to eat too much, the daily consumption is not to exceed their finger volume is appropriate.

In order to implement the "People's Republic of China environmental protection" and "People's Republic of China water pollution prevention law", protect the environment, safeguarding human health, standard method for the determination of nitrosamines in the water. Determination of surface water, underground water, industrial wastewater and domestic sewage nitrosamine compounds by gas chromatography.

亚硝胺类化合物属亚硝基化合物,包括亚硝胺与亚硝酞胺两类,是亚硝酸盐与胺类特别是仲胺合成的一大类化学物质,均含有N一亚硝基基团。大多数可致人体中毒甚至有极强的致癌性,对人类健康造成*危害。而导致食道癌形成的原因之一就有它—亚硝胺类化合物。
