摘　　要：用常规方法检测了胃癌高发区山东省牟平县高陵镇居民饮用水(井水)样122份,硝酸盐含量为4.4～497.2ppm,平均109.6ppm;亚硝酸盐含量 ND(未检出)～0.538ppm,平均0.020ppm。水井有手压井(机井)和公用井两种类型。井水可分为成、稍咸和甜三种水质。井水硝酸盐含量在不同水井、水质类型间有显著性差异。本研究表明,当地居民饮水中硝酸盐含量普遍较高,不同家庭间饮水的水质及其硝酸盐含量存在一定差别。122 samples of well water drunk by inhabitants from a high-risk area for stomach cancer,Gaoling To- wnship,Moping County(Shandong Province)were anal- ysed for the presence of nitrate and nitrite with rou- nting methods。The nitrate contents ranged from 4.4 to 497.2 ppm with an average of 109.6 ppm;the nitrite contents from ND(not detected)to 0.538 ppm with an average of 0.020 ppm.There were two kinds of wells:Domestic wells and public wells。The we llwater could be divided into three types of water quality:Salt, mild-salt and sweet。There were significant differences in nitrate contents among the various types of water The present study shows that the nitrate levels in the local inhabitants'drinking water are generally high,and apparent differences in water quality and nitrate level may exist among the families.
