Heavy metals distribution in dissolved and particulate phases in Dongting Lake, China
The concentrations of particulate and dissolved metal in flood season are higher than that in drought season in Dongting Lake, China. The concentrations are also significantly high in the entrance and exist of the lake. Proportions are different between particulate metal and dissolved metal. Manganese concentrates in particulate phase, As concentrates in dissolved phase, other metals such as Cu, Pb, Zn, Cd, Ni and Hg frequently migrate between particulate phase and dissolved phase, which can be attributed to seasonal and regional factors.Upon comparison of the concentration coefficient of suspended particulate matter (SPM) and water phase among different water bodies in the world, the metal concentration ability is placed in the middle in Dongting Lake water. The log (Kd) values indicate poor correlations against SPM concentrations.
