摘要

摘要: “八五”期间在食管癌高发区磁县，对其9个乡饮用水源情况进行了全面调查，对水源三氮含量（硝酸盐氮、亚硝酸盐氮、氨氮）连续四年进行监测；对磁县1991～1996年氮肥使用量进行统计，并以省内食管癌低发区赤城作对照。结果表明：防治区水源污染严重，水源三氮含量、氮肥使用量均显著高于赤城，且存在显著差异（P<0.01）。水源三氮污染与使用氮肥有密切关系，三氮含量与食管癌死亡率呈明显正相关。

Abstract: The pape beiongs to the primary prevention section of the National Eighth Five - year Research Programme of the prevention research programme in areas with the highest cancer incidence rates.The study found that drinking water in chixian county is heavily polluted. The contents of nitrate nitrogen, nitrite nitrogen and ammonia nitrogen are higher than national cermissive levels by 20. 60%,50.50% and 33.3% perspectively. The contents of nitrate nitrogen, nitrite nitrogen and ammonia nitrogen in Chixian are sighficantly higher than that in Chichen county - an area with very low incidence rate of esophagus cancer in Hebei province. The amount of N - containing fertilizer used in Chixian was higher than that in Chichen. The results indicates that levels of three nitrogen in drinking water correlates both with the amount of N - containing fertilizer used and with the mortality rates of the esophagus cancer.
