Metal elements are the most common and widely distributed chemical elements in nature,which are closely related to human health,and their excess or lack will have a profound impact on the physio-logical and pathological processes of the body.This paper defines the concept of"metal element stress re-sponse",that is,the stress response that can occur in various cells,tissues and organs throughout the body when the content of metal elements in the body exceeds or falls below a certain level.According to the degree of stress,it can be divided into four dimensions:physiological stress,burden stress,pathological stress and disease stress.This paper comprehensively describes the degree,mode and biological effect of the interaction between metal elements and organism,and"four-dimensional theory"of metal element stress response is pro-posed,aiming to provide new ideas and new methods for seeking the potential intervention strategies of metal element stress response in the future
