摘要
据不同地貌、地质条件在３０个县市按剖面、同步、随机取土壤样品３７２份，测定硒等微量元素含量，作等级相关分析显示：土壤硒含量与消化系统癌呈负相关关系．作相对危险度、剂量－效应及多因素分析，认为此负相关关系并非偶然现象。
Trace elements contents of 372 soil samples randemizely from 30 counties of Jiangxi province were measured. The result showed that the selemium content appeared nagtive cortelation to alimentary system cancer. and the analyses of relative risk. dose-effect and of multiple factor were made.
