STUDY ON THE CHARACTERISTICS OF BOTTOM SEDIMENTS IN LAKE HIBARA

Abstract

The characteristics of bottom sediments are most important that factor of water quality in epilimnion of summer. This study of aims at to make clear bottom sediments based on flow process from heavy metals and nutrient salts. Heavy metals and nutrient salts of bottom sediments were investigated based on quantity and qualitative analysis in Lake Hibara. The characteristics of geographical distribution of heavy metals and nutrient salts were shown in bottom of this lake. Transportation of heavy metals and the process of generating were shown from the relation between particle diameter and nutrition salt.
