Abstract
Mercury mass balance was investigated in Lake An-dong, located in the upper stream of the Nakdong River, to assess the status of mercury pollution by measuring mercury inputs and outputs of the lake. The parameters for mercury input estimation included atmospheric wet deposition (0.52 kg/yr), dry deposition (0.20 kg/yr), river inflow (16.93 kg/yr) and diffusion from lake sediments (0.64 kg/yr). The mercury inputs totaled 18.29 kg/yr, and 92.5% of this total input was attributed to river inflow from the upper stream. Mercury outputs were measured in evasion (0.14 kg/yr), lake outflow (1.92 kg/yr) and sedimentation (45.77 kg/yr), and the total mercury output was estimated to be 47.83 kg/yr. The imbalance between the inputs and outputs of mercury was 29.54 kg/yr, which suggests that there are other missing inputs of mercury to Lake An-dong such as river input during heavy rainfalls and tributary inflow.
