Abstract

This study was performed to characterize the seasonal variation of water quality and sediment environment from February, 2007 to October, 2007 in 21 stations of Gwangyang bay. $6.03\sim11.98mg/L$ on surface and $4.43\sim10.71mg/L$ on bottom in DO, $0.12\sim3.16mg/L$ on surface and $0.20\sim2.64mg/L$ on bottom in COD, $0.23\sim18.28{\mu}g$-at/L on surface and $0.33\sim9.56{\mu}g$-at/L on bottom in DIN, ND$\sim1.47{\mu}g$-at/L on surface and $0\sim4.56{\mu}g$-at/L on bottom in DIP. IN sediment the ranges were $2.86\sim21.17%$ in IL, $0\sim6.11mg/g$-dry in AVS and $2.64\sim23.23mg/g$-dry in COD.

광양만 해양수질 및 저질의 계절적 변동에 관한 조사를 위해 2007년 2월부터 2007년 10월까지 광양만의 21개 정점을 선정하여 계절별로 관측하였다. 용존산소(DO)는 표층에서 $6.03\sim10.98mg/L$와 저층에서 $4.43\sim10.77mg/L$, 화학적산소요구량은(COD)표층에서 $0.12\sim3.16mg/L$와 저층에서$0.20\sim2.64mg/L$, 용존무기질소(DIN)는 표층에서 $0.23\sim18.28{\mu}g$-at/L와 저층에서 $0.33\sim9.56{\mu}g$-at/L, 용존무기인(DP)은 표층에서 $0\sim1.47{\mu}g$-at/L와 저층에서 $0\sim4.56{\mu}g$-at/L 농도를 보였다. 퇴적물에서의 강열감량은(IL)은 $2.86\sim21.17%$, 산 휘발성황화물은(AVS)은 $0\sim6.11mg/g$-dry 그리고 화학적 산소요구량(COD)은 $2.64\sim23.23mg/g$-dry 의 농도분포를 보였다.
