이화학적 분석방법의 단점은 무엇인가? | 매년 새롭게 개발되어 연안해역으로 유입되는 화학물질의 종류만 해도 수백여 종에 이르고 있어, 이들 물질을 하나하나 분석하여 파악 및 규제한다는 것은 현실적으로 불가능할 뿐만 아니라, 많은 시간과 경제적 비용이 소요된다는 점도 간과할 수 없는 현실이다. 또한, 이러한 이화학적 분석방법은 수계에 존재하는 잠재적인 독성여부와 유해물질이 공존할 경우 발생하는 독성 상승 또는 길항효과에 대한 판단을 할 수 없다는 단점이 있다(Rand and Petrocelli, 1985). | |
생태독성에 사용되는 시험생물 종은 어떤 조건이 있어야 하는가? | , 1998; Yu, 2004). 또한, 생태독성에 사용되는 시험생물 종은 취급이 용이하고 시험비용이 적게 들 뿐만 아니라, 독성물질에 대한 높은 민감성과 다양한 지표적 특징을 지녀 정확한 평가가 가능해야 한다(Hwang et al., 2008; Park et al. | |
이화학적 분석방법을 보완하기 위해 어떤 방법이 개발되어 이용되고 있는가? | 이러한 분석 방법을 보완하기 위해 구미 선진국에서는 단일 유해물질 혹은 다양한 유해물질이 포함되어 있는 해수 및 퇴적물에 대한 독성을 평가하기 위하여 생물검정법이 개발되어 각 나라의 실정에 적합한 생태독성시험법이 이용되고 있다(APHA et al., 1995; ISO, 1995; ASTM, 1996; NIWA, 1998; USEPA, 2002). |
