阿坝大骨节病区青稞中8种元素的比较分析

Comparative analysis of 8 elements in barley collected from A'ba sichuan Kashin-Beck Disease area

目的:探讨阿坝县大骨节病区、消退区、非病区青稞中8种元素的差异。方法:对阿坝县大骨节病区、消退区、非病区青稞中Cu、Zn、Pb、Cd、As、Hg、Cr、F8种元素进行对比分析并且将这8种元素与患病率做单相关分析,筛选出与患病率显著相关的元素。结果:Cu含量在病区和消退区之间差异显著;Hg含量在病区与非病区之间差异显著,As和Cr元素在病区、消退区、非病区之间呈递减趋势;与患病率做单相关分析,发现青稞中Cu、Zn含量与患病率呈显著正相关关系。

Objective：To investigate the roles of 8 elements in the barley of the Kashin-Beck Disease（KBD） areas,subside areas and control areas.Methods：To compare the concentrations of Cu,Zn,Pb,Cd,As,Hg,Cr and F in the barley collected from KBD areas,subside areas and control areas and make the single correlation analysis between the elements and the prevalence rate,choose the significantly associated element.Results：The element of Cu had significant difference between KBD areas and subside areas;The element of Hg had significant difference between KBD areas and control areas.The element of As and Cr were less and less among KBD areas,subside areas and control areas.
