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.

충주호의 지류인 제천천 하류에서 주기적으로 발생하는 남조류 과다증식의 현황과 오염원을 분석하였다. 2015년 10월 18일과 2016년 9월 25일에 제천천 하류의 명서낚시터지점(GPS; 37°03'25.5"N, 128°03'13.6"E)에서 클로로필 a의 농도는 각각 399.2, 184.8 mg m-3이었으며, 남조류독소인 microcystins의 농도는 각각 124.09, 79.71 ㎍ L-1이었다. 명서낚시터 지점에서 남조류 과다증식은 충주호의 수위 및 수위변화와 매우 밀접한 관계가 있는 것으로 나타났다. 즉 수온이 남조류 성장에 적합한 조건에서 충주호 수위가 상승하여 수체가 정체되는 시기에 남조류 과다증식이 발생한다. 제천천에 위치한 환경부의 수질측정망 자료를 분석한 결과, 제천하수종말처리장이 위치한 장평천이 주요 오염 지류인 것으로 나타났다.

The occurrence of cyanobacterial blooming and the contaminant sources were analyzed in the downstream of Jecheon Stream, a tributary of Chungju Reservoir. The concentrations of chlorophyll a at the Myungseo Fishing Point (GPS; 37°03'25.5"N, 128°03'13.6"E) were 399.2 and 184.8 mg m-3 on...
