全国约79％的人饮用次生污染的水,7亿人饮用大肠杆菌含量超标的水,1.7亿人饮用有机物污染的水,3000万人饮用高硝酸盐水,1000万人饮高氟水。 自来水内含有多种有害物质。而且自来水有二次污染,不宜直接入口。 开水中存在致癌物质。煮沸水增加水中有害物浓度,降低有益人体的溶解氧含量,而且也使亚硝酸盐等致癌物增加。 从水的结构上分析,生水比开水更利于人的健康。
About 79% of the people in the country drink secondary-contaminated water, 700 million people drink water with excessive E. coli content, 170 million people consume organic-contaminated water, 30 million people drink high-nitrate water, and 10 million people drink high-fluorine water. Tap water contains a variety of harmful substances. And tap water has secondary pollution and should not be directly imported. There are carcinogenic substances in boiling water. Boiling water increases the concentration of harmful substances in the water, reduces the dissolved oxygen content of the body, and increases the carcinogens such as nitrite. From the structural analysis of water, raw water is more conducive to human health than boiling water.
