江西省直肠癌与岩石类型的关系

Relations Between the Cancer of Rectum and the Types of Rocks in Jiangxi Province

利用岩石类型资料 1 0 92个数据 ,直肠癌死亡调查资料 1 686例 ,研究了直肠癌死亡率与人群生存区的岩石类型 (岩浆岩、变质岩、碳酸盐岩、碎屑岩、红色碎屑岩、第四系松散岩 )的相关性。结果表明 ,变质岩、碳酸盐岩、第四系松散岩与直肠癌死亡率有明显的相关性 ,等级相关系数分别为 0 .31 34 (P <0 .0 0 2 5) ,0 .332 1 (P<0 .0 0 1 ) ,0 .2 532 (P <0 .0 1 )。但与岩浆岩、碎屑岩。

This paper presents the studis on the relativities between the death rate of the recfum cancer and in the types of rocks(magmatic rock,metamrphic rock,carbonate rock,clastic rock,red clastic rock and friable rock of quaternnary sestem)in the people living areas of by means of the information of rock types with 1 092 data and the investigations of 1 686 examples about the death rate of the reefum cancer.The result shows that the death rate of the nectum cancer is evidently corelated with metamrphic rock,carbonate rock,friable rock of quaternary sestem;correlation coefficient of gradation is 0.313 4( P < 0.002 5 ),0.3321( P <0.001),0.2532( P <0.01)nerpectrvely,but has no correlation with magmatic rock,clastic rock,red clastic rock.
