dc.description.abstract 인천항에서 선박평형수 배출수에 기인한 외래종을 고려한 항만환경 관리수준 설정을 위해 식물플랑크톤의 잠재적 위해종 출현 특성과 관련된 환경영향 요인을 2007년 2월부터 2009년 11월까지 인천항 내측 및 외측에서 계절조사를 수행하였다. 조사결과, 한국 주변해역에서 출현한 바 있는 식물플랑크톤 62종이 관찰되었고, 그 중에 적조원인종 13종과 독소생산종 7종의 잠재적 위해종이 관찰되었다. 잠재적 위해종은 여름철과 겨울철에 인천항 외측에서 더 다양하게 출현하였다. 봄과 겨울철에는 적조원인종인 Skeletonema spp., Thalassiosira nordenskioldii, Paralia sulcata가 항만 내측 (평균 72.4%) 및 외측(평균 77.6%)에서 모두 우점 하였고, 수소이온과 부유물질의 농도와 양의 상관관계를 나타냈다(p 3.05μg/L , 1.49μg/L , 5.46μg/L 로 내측보다 3-5배 높은 농도가 높았고, 겨울철에는 내측 (평균 0.94μg/L ) 및 외측 (평균 0.95μg/L ) 간 농도 차이가 없었다. 요약하면, 인천항 외측은 다양한 적조원인종이 우점하며 엽록소-a 농도가 높았으나, 항만 내측은 여름철 독소생산종의 출현 종수가 높게 나타났고, 외측에 비해 엽록소-a 농도가 낮았다. 각 위해종들의 대 발생 가능성은 영양염, 화학적 산소요구량 및 부유물질의 농도와 비례한 것으로 나타나, 항만 내, 외측의 환경특성을 고려한 잠재적 위해종 관리가 요구된다. This study examined the occurring pattern of potential risky species and the related abiotic factors for port-specific environmental management considering the control of ballast water-induced foreign species at Incheon seaport. From a total of 62 species observed during the study, 13 red-tide and 7 toxic phytoplankton, normally occurring species in Korean waters, occurred from the seasonal investigation at the inner and outer sites of the Incheon seaport from 2007 to 2009. The number of potential risky phytoplankton was relatively high at the outer site of the port during summer and winter. Red-tide species, such as Skeletonema spp., Thalassiosira nordenskioldii, and Paralia sulcata, dominated the total standing crops at the inner site (avg. 72.4%) and outer site (avg. 77.6%) in spring and summer, being positively correlated with the concentrations of total suspended solids (TSS) and pH (p 5.46μg/L on average, which was 3-5 times higher than that at the inner site in spring, summer and autumn, whereas there was no difference in the concentration between inner (avg. 0.94μg/L ) and outer (avg. 0.95μg/L ) sites in winter. In summary, diverse red-tide species dominated and a relatively high chl-a concentration existed at the outer site, whereas a relatively high number of toxic species and low chl-a concentration was observed at the inner site in summer. The potential risky species can outbreak in association with the concentration of nutrients, COD and TSS, suggesting that distinctive management of potential risky species is needed considering the environmental characteristics of Incheon seaport. -
