Temporal and spatial characteristics of pollutant loads from the various pollution sources in Kwangyang Bay were evaluated. Total discharging loadings of BOD, TN, and TP by unit loading estimation were 11,524 ㎏/day, 11,536 ㎏/day, and 827 ㎏/day, respectively, and were mainly affected by the industrial and population sources. The Yeosu and Kwangyang cities as administrative district had the highest pollutant loads. Flow rate ranges from about 30-4,406,400 ㎥/day in December to 240-35,337,600 ㎥/day in August with a flow rate of PS27 (the Seomjin River) as the highest one. Total COD, TN, and TP loadings in August were about 89,915 ㎏/day, 2,077,845 ㎏/day, and 50,123 ㎏/day, respectively, which exceeded those of December. Especially, of input sources, the Seomjin river had the most pollutant loads. Wastewater discharging loads from the water treatment facilities was the greatest contributors to pollutant loads in the inner part of Kwangyang Bay. Point sources located in south-western part of the bay showed high concentration in heavy metals distribution. Seasonal variations of pollutant loads were related to the changes of flow rate, those were increased rapidly on August, 2004. For the improvement of water quality in this area, pollutant loads were reduced within the limits of the environmental capacity.

Especially, of input sources, the Seomjin river had the most pollutant loads. Wastewater discharging loads from the water treatment facilities was the greatest contributors to pollutant loads in the inner part of Kwangyang Bay. Point sources located in south-western part of the bay showed high concentration in heavey metals distribution. Seasonal variations of pollutant loads were related to the changes of flow rate, those were increased rapidly on August, 2004. For the improvement of water quality in this area, pollutant loads were reduced within the limits of the environmental capacity.
