“…Detailed descriptions of the metal digestion and organic extraction followed by clean-up procedure and instrumental quantification for various types of environmental samples are presented in our earlier publications 8,9,40,41 . General properties of sediment samples including total organic carbon (TOC), sediment grain size are analyzed additionally and laboratory and field blank samples were concurrently analyzed to crosscheck the procedural contamination in terms of QA/QC.…”

Here we present our triad approach followed by major findings based on sediment pollution studies that determined the chemical concentration, biological effect, and community structure associated with trace pollutants in the Korean coastal environment. Since the late-1990s, over several hundred sites along the Korean coast have been surveyed including sediment (including pore-water), water, and biological samples and analyzed for instrumental quantification, in vitro and in vivo bioassays, and benthic community indices. The instrumental data of persistent heavy metals and organic pollutants in Korean sediments generally suggest that concentrations of target pollutants are relatively low to moderate but their distribution is widespread across the coasts. The compositional pattern and spatial distribution suggests that their sources are independent of each other. However, there are local zones with extremely high concentrations of certain pollutants indicating point sources. In order to search for the relationship between chemical concentrations and biological responses, some selected data (n=123) were further analyzed in terms of mass balance analysis (sediment-TIE towards TEQ approach). Most of the dioxin-like activities were observed in the fractions containing dioxins, furans, and certain polycyclic aromatic hydrocarbons (PAHs) and about half of the samples showed significant estrogenic activities in the fractions of PAHs and alkylphenols. Direct relationship(s) between chemical and ecotoxicological data could not be fully addressed between component(s). However, a positive relationship between them became apparent in some cases, indicating a general good agreement between chemical stresses and biological responses. Overall, we found that a sediment triad approach for an integrated assessment of trace pollutants in the coastal environment was extremely useful. It would be much more powerful when all the components are fully and simultaneously analyzed and interpreted.

This study was conducted to investigate the impact of sand addition to an intertidal for the development of the Manila clam habitat on benthic community structure. For this, we focused on the spatio-temporal changes in the surface sediment condition and benthic community structure before and after the event. Study site was an sandbank in Gonam-myeon, Taean-gun where sand added to on July 2010. We set three stations at each of sand adding area (experimental plot) and non sand-adding area (control plot) and did sampling works ten times from June 2010 to October 2011. Directly after the event, surface sediments changed to very coarse sand, but the state was not maintained over four months because of seasonal sedimentation and finally got back to very fine sand in eight months. The number of species and density were temporarily reduced right after the event and crustacean species such as Apocorophium acutum, Photis sp. were most negatively affected by the event. However, the number of species recovered from the reduction in three months and density did in four months due to the recolonization by the existing species and species in the vicinity of the plot. During the study period, dominant

“…Ecologically significant responses of estuarine benthic assemblages to anthropogenic pollution are usually measured by changes in the diversity of the macrobenthos (Ryu et al, 2011), based on the assumption that such disturbance will induce changes in species composition, abundance and biomass (Pearson and Rosenberg, 1978). However, the majority of diversity studies addressing the spatial and temporal patterns of variability in communities facing anthropogenic pressures have been focused on local and regional diversity (alpha-and gamma-diversity, respectively).…”
