亚硝酸盐是致癌物亚硝胺的前身物之一,可从饮水进入人体。已有报道:开水中的亚硝酸盐较其生水为高,引起了人们的关注。为探讨开水中亚硝酸盐增加的规律,我们作了“过夜保温”与“新水新烧”法烧开水过程中亚硝酸盐含量的对比分析。现简要报道如下: 用塑料桶采湘江河水、本院水管自来水及附近土井水三种水样,将每份水样(10L)
Nitrite is one of the precursors of carcinogenic nitrosamines, which can enter the body from drinking water. It has been reported that nitrite in boiling water is higher than that of raw water and has aroused people’s attention. In order to explore the regularity of nitrite increase in boiling water, we made a comparative analysis of nitrite content in boiling water during “overnight warm” and “new water new burning” method. Now briefly reported as follows: The plastic barrel mining Xiangjiang River, the hospital water pipes and soil around the three kinds of soil samples, each of the water samples (10L)
