山东栖霞_临朐一带新生代火山岩与胃癌相关关系探讨

A RESEARCH FOR THE RELATIONSHIP BETWEEN THE GASTRIC CANCER AND THE CENOZOIC VOLCANIC ROCK IN QIXIA AND LINJU AREAS, SHANDONG

摘要:

山东栖霞、临朐一带是山东胃癌死亡回顾调查中居首、二位的显著高死亡区。它与栖霞复背斜和临朐坳陷中的新生代火山岩区区域地质背景相吻合。火山岩受沂沭断裂和栖霞断裂等深断裂制约。山东栖霞、临朐一带新生代火山岩为富含Cr、Ni元素的地幔源基性、超基性火山喷发、分异混染、混杂玄武岩。Cr、Ni元素已被世界卫生组织国际癌症研究中心(IARC)确认为Ⅰ级、ⅡA级致癌物,与癌病有肯定的因果关系。据此推论,栖霞、临朐的新生代火山岩中Cr、Ni元素的地球化学行为是导致栖霞、临朐成为胃癌显著高死亡区的根本原因之一。

Abstract:

The epidemiological study on the gastric cancer death in Shandong Province has shown that Qixia and Linju counties are the areas with the highest mortality which is thought to be related to the regional geological background, as the Cenozoic volcanic rocks have been found in the Qixia anticlinorium and the Linju depression but are rarely found elsewhere in Shandong. The volcanic eruptions were controlled by such deep fractures as the Yishu fracture, the Qixia frature, etc.The Cenozoic volcanic rocks in the ...
