| 摘 要： | 阐明了林州市食管癌流行的4个特征。根据46个饮用水的NO3^-分析资料，论证亚硝胺的前体物NO3^-的分布与食管癌的地理分布具有明显的相关性：林州市的发病率是北部高于南部；林州市－安阳县－范县的发病率是西部大于东部。居民饮用NO3^-超标的浅层地下水，旱井水是导致食管癌的重要原因之一。70年代以来，大量施用化肥是引起饮用地下水NO3^-污染的根本原因，它导致的后果是林州市食管癌发病率和死亡率下降缓慢。指出了必须坚持“防霉、去胺、施钼肥、治增生、改变不良饮食习惯”五项预防措施，特别要把饮用水治理好。

| Abstract: | The discussion of the four characteristics of esophagus cancer in Linzhou reveals that the geographical distribution of NO - 3 and esophagus cancer can be obviously correlated from analytical data for drinking water NO - 3 of 46 samples.It is found that northern Linzhou has a high NO - 3 content in drinking water than its southern part and that western Linzhou Anyang Fanxian is larger than the eastern part.The excessive content of NO - 3 in drinking water is one of the important causes of esophagus cancer.Since 70's,the excessive utilization of chemical fertilizer has caused the contamination of NO - 3 in drinking water.Therefore,the rate of disease and death of esophagus cancer in Linzhou is slowly decreased.We propose that five measures must be taken:prevent the mildew,move the amine,use the fertilizer of molybdenum,treat the hyperplasia,change the bad habit of drinking and eating,particularly manage the drinking water. |
