【摘要】 目的研究水体污染状况及其与恶性肿瘤死亡率的关系。方法在福建省福清市和永泰县部分乡镇进行死因调查,并对其水体污染物含量进行检测。结果(1)饮用水中超标的指标有pH值、氟、铅、铁和锰,锰的超标率福清市显著高于永泰县(P<0.05)。(2)福清市地表水总氮、磷的超标率分别为55%和25%,而永泰县这2项指标的超标率均为0%,福清市总氮、磷的超标率显著高于永泰县(P<0.05)。(3)福清市微囊藻毒素检测阳性率为46.5%,显著高于水泰县的阳性率11.0%。(4)福清市恶性肿瘤的标化死亡率是永泰县的2倍,其中食管癌、胃癌、肝癌、肠癌、肺癌、膀胱癌标化死亡率福清市均高于永泰县。结论福清市恶性肿瘤高死亡率可能与水体严重污染有关。更多还原

【Abstract】 Objective To study the correlation between the status of water pollution and cancer mortality.Methods Investigation into water pollution and the cause of death were carried out in some parts of Fuqing and Yongtai.Results The indexs above the national standards in drinking water were pH,fluoride,lead,iron,manganese.The over standard rate of manganese in Fuqing was significantly higher than that in Yongtai.The over standard rate of total nitrogen and total phosphorus in Fuqing was 55% and 25% respectively,and the rate in Yongtai were 0%.The rate in Fuqing was significantly higher than that of in Yongtai(P<0.05).The positive reaction rate of microcystin in Fuqing was 46.5%,which was significantly higher than that of in Yongtai(11.1%,P<0.05).The standardized mortality of cancer in Fuqing was one time higher than that of in Yongtai.The standardized mortality of esophageal,stomach,liver,colorectal,lung and bladder cancer in Fuqing were higher than those of in Yongtai.Conclusion The high mortality of cancer in Fuqing may be correlated with water pollution.更多还原
