조류 대발생을 방지하기 위하여 필요한 것은? | , 2007). 그러므로 조류 대발생을 방지하기 위하여 외부기원 질소원(농약 및 비료, 축산폐수, 공장폐수, 생활하수 등)의 지속적인 조사와 관리가 매우 필요하다. | |
조류란? | 조류 (algae, 藻類)란 양치식물이나 관속식물을 제외한 광합성을 하고 산소를 생성하는 단세포 진핵생물인 원생생물 (protist)과 남조류 (blue-green algae)라고 부르는 원핵생물인 남세균 (cyanobacteria)을 통칭한다 (Suikkanea et al., 2010). | |
조류 대발생이 일으키는 사회적 문제는? | 녹조현상 같은 조류 대발생은 주로 생활하수를 포함한 점오염원과 농지 및 산림으로부터 유출되는 불특정 비점오염원의 유입에 따라 수계 내 과도한 영양물질(질소, 인) 축적이 이루어져 나타난다(Hargrave, 1991). 또한 심미적 불쾌감, 용존산소 고갈에 따른 어류폐사(Sinonen et al., 1999), 독소 및 이취미 발생, 정수장 여과지 폐색과 같은 사회적 문제를 일으킨다(Watson et al., 2004, 2007; Van Apeldoorn et al. |
