연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Abstract AI-Helper 아이콘AI-Helper

Grain size, the content of ignition loss (IL), and the concentrations of chemical oxygen demand (COD), acid volatile sulfide (AVS), and trace metals (Fe, Mn, Cu, Pb, Zn, Cd, Cr, As, and Hg) in surface sediments from the Taehwa River estuary, Ulsan, were measured to evaluate pollution levels and pote...

문제 정의

  • 따라서, 이 연구에서는 도심하천의 영향을 받고 있는 태화강 하구 퇴적물 중 미량금속의 분포특성과 오염도를 평가하고자 하였으며, 이를 위해 태화강 수계 중 울산만의 해수가 영향을 미치는 삼호교 부근에서부터 울산항 입구까지를 연구해역으로 선정하여 하구 퇴적물 내 미량금속 중 철(Fe), 구리(Cu), 카드뮴(Cd), 납(Pb), 크롬(Cr), 망간(Mn), 비소(As), 아연(Zn), 수은(Hg) 농도를 조사하였다.
  • 하지만, 퇴적물 환경기준에 있어서 미량금속 중 Cu와 Zn은 보정원소인 리튬(Li)을 이용하여 입도의 영향을 보정한 농도와의 비교를 권고하고 있으나, 이 연구는 기준이 설정되기 이전에 조사가 이루어져 보정원소에 대한 자료가 없다. 따라서, 이 연구에서는 전 세계적으로 퇴적물 중 미량금속 오염평가에 널리 이용되고 있는 미국 해양대기청(National Oceanic and Atmospheric Administration, NOAA)에서 설정해 놓고 있는 ERL (effect Range Low) 농도(Buchman, 2008)와 비교하여 퇴적물 중 미량금속 오염도를 살펴보았다.

핵심어 질문 논문에서 추출한 답변
태화강 하구는 어떤 특징을 가지고 있는가? 한반도의 남동쪽에 위치하고 있는 태화강은 울주군 상북면 가지산에서 발원하여 둔기천, 동천, 여천천 등의 지류가 모여 형성된 길이 48 km, 유역면적 644 km2인 국가하천으로 울산시의 도심을 가로질러 최종적으로 울산만으로 유입되는 우리나라의 대표적인 도시하천 중에 하나이다(Rhyu, 1993; Kim and An, 2010). 태화강 하구(Taehaw River estuary)는 태화강 하류에 형성된 개방형의 하구로 하류부의 하폭이 약 300 m, 하상경사는 약 1/2,000-1/4,000 로 매우 완만하여 울산만의 조차에 의해 강물의 수위 및 유속이 주기적으로 변하며, 밀물시 하류로부터 약 10 km 상류에 위치한 삼호교까지 해수가 유입되어 영향이 미치는 것으로 알려져 있다(Cho et al., 2011; Cho and Yoon, 2011).
국내에서 상대적으로 규모가 큰 국가하천은 총 몇개인가? 우리나라에서 하구로 정의할 수 있는 지방하천 규모 이상의 하구는 전체 3,832개 하천 중 449개이며, 이중 상대적으로 규모가 큰 국가하천 규모의 하구는 총 13개가 있다(Cho et al., 2007; Lee et al.
태화강 환경개선사업으로 나타난 부분적인 생태계 복원효과는? , 2013). 또한, 연어가 회귀하고 서식 물고 기 개체수가 증가하였으며, 하류에 바지락 자원의 서식밀도가 높아지는 등 부분적인 생태계 복원효과가 나타나고 있다(Park et al., 2010; Choi et al.
