A Study on the Environmental Chemistry of Toxic Trace Elements in the Large Area Water Body

Abstract

This paper adopts the research approach of trace element environmental chemistry, conducts a tracer study on the cyclic process of toxic trace elements in the chemical substances in the watershed from the perspective of time and space, and studies the content, the distribution, the distribution characteristics mechanism in different phases as well as the influencing factors of toxic trace elements and other trace elements. Test results have demonstrated that the water chemistry characteristics of the small watershed in the southern Jiangxi Province affect the content and the distribution pattern of the dissolved trace elements. The pH value of the river water is the most significant factor that controls the behaviors of the dissolved trace elements in the river water. The content of the dissolved trace drops with the increase of pH value. Trace content and its value have showed an inverse relationship.
