Abstract
- The evaluation of the health status of thecoastal ecosystem is an important task for marine environmentalmanagement. To determine the “good health status from chemicalpollution” in coastal areas, a combination of multiple data sets fromvarious organisms is needed. Marine ecosystems are complex anddynamic systems. Therefore, the interpretation of results derived fromenvironmental monitoring based only on measurements at the ecosystemlevel is extremely difficult. To evaluate the health status at six differentstudy areas, we used the generalized linear model approach withselected biochemical markers in resident fish from uncontaminated andcontaminated sites. We also confirmed the independence between thebiochemical indices and the morphometric indices including the hepatosomaticindex (HSI), gonado-somatic index (GSI), and condition factor(CF) in fish from the sampling areas. The effect of area on the presenceof biotransformation markers (ethoxyresorufin-Odeethylase activity EROD) was significantly high in Masan Bay. The area with the greatesteffect on acetylcholinesterase (AChE) activity was Jindong Bay, whilethere was no significant effect of GSI, HSI, CF, and sex in the ERODmodel and HSI, CF and sex in the AChE model. These results clarifythat fish from Masan, Gwangyang and Jindong Bay were affected bypollutant stress, and the analysis of sensitive biochemical responsesallowfromvarious organisms is needed.
