Estimation of the Sediment Pollution in Coast of Gwangyang, Mokpo and Shinan, Korea

Abstract

We estimated sediment pollution by the analysis of COD and AVS. We also estimated the contents of Cu, Cd, Pb, Zn in sediment of Gwangyang bay, Mokpo inner bay and Shinan Bigum coastal area from 2011 July to 2012 February. In these results of sediment COD and AVS show III level pollution in Mokpo inner bay, however Gwangyang and Shinan Bigum coast show I level pollution. The results of Igeo show over 2 on the contents of Cu and Cd in Gwangyang bay and Mokpo inner bay. It also know that Igeo can more and detail estimate sediment pollution in industrial coastal area. These results show that it is suitable to estimated sediment pollution by COD and AVS with trace metal in industrial and initial polluted coastal area rather than analysis of COD and AVS only in coastal area.

Distribution of metal contamination and grain size in the sediments of Nakdong River, Korea

“…These studies typically assess the contamination level by comparing with the absolute baseline values of sediment quality guidelines (SQGs) derived for each country. Another typical assessment method employs the concentration of metals among crustal materials or in an uncontaminated area as the background concentration for comparison (Sekabira et al 2010 ; Kim and Um 2013 ; Md et al 2015 ; Han et al 2016 ).…”

Assessing Nutrient Limitation in Yeongsan River Estuary Using Bioassay Experiments

“…The Yeongsan River estuary, the focus of this study, has been experiencing increased water pollution, particularly high concentrations of nutrients (total phosphorus and total nitrogen) and organic matter owing to domestic sewage and wastewater, since the construction of a sea dike in December 1981 [17]. The opening of sluice gates at the dike results in a considerable inflow of freshwater with high concentrations of nutrients and organic matter into Mokpo Port, causing changes in its water quality [18].…”
