초록

해양생태독성평가를 위한 공정시험방법으로 해양생태계의 기초생산자를 대표하는 식물플랑크톤인 Skeletonema costatum, Heterosigma akashiwo, Prorocentrum micans, Isochrysis galbana, Tetraselmis suecica를 이용하여 생물 검정 예비 실험을 수행하였다. 그중 표준시험생물로 해산규조류인 S. costatum을 표준시험생물종으로 선정하였으며, Endpoint는 $72{\sim}96$시간 개체군성장저해율($EC_{50}$)로 설정하였다. 시험방법은 비교환정수방식(non-renewal static test)을 선택하였으며, 시험적합도 기준은 대조구의 시간당 개체군성장률 0.04(r > 0.04/hr) 이상으로 설정하였다. S. costatum은 우리나라는 물론 전 세계적으로 널리 분포하며, 표준시험방법개발은 국제표준화기구(ISO, International Standardization Organization)의 시험방법을 참고하였다. 본 종을 이용한 독성시험은 시험대상물질의 염분이 $20{\sim}35\;psu$의 범위에서 가능하며, 반복실험 및 교차분석결과 표준독성물질에 대한 민감도가 유사하게 나타남으로써 실험의 재현성이 입증되었다. 하수오니 용출액을 이용한 독성실험 결과, 식물플랑크톤의 개체군성장저해율($EC_{50}$)을 이용한 독성실험은 윤충류(Brachionus plicatilis) 신생개체(neonate)의 사망률($LC_{50}$), 발광박테리아(Vibrio fischeri)의 발광저해율($IC_{50}$), 해조류(Ulva pertusa)의 생식률($EC_{50}$)을 이용한 시험방법보다 낮은 농도에서 $EC_{50}$을 나타냈다. 식물플랑크톤의 개체군 성장저해율을 이용한 생물검정 방법은 유해물질의 해양 기초생산자에 대한 독성평가에 매우 유용한 실험 방법으로 판단된다.

A series of experiments were conducted to establish a marine ecotoxicological standard method using marine primary producers, Skeletonema costatum, Heterosigma akashiwo, Prorocentrum micans, Isochrysis galbana, Tetraselmis suecica as candidate test species. Marine diatom, S. costatum was selected as standard test species in terms of the ecological roles and international uses as test species. Test methods and test acceptability criteria are as follows; $72{\sim}96$ hr population growth inhibition $EC_{50}$ as endpoint. Static non-renewal method, and population growth rates over 0.04/hr in control as test acceptability criterium. S. costatum is widely distributed in the world ocean and used for standard species of marine toxicity test method by ISO (International Standardization Organization). Possible salinity ranges for this test method are $20{\sim}35\;psu$, and reproducibility and interlaboratory test results were consistent through the calibration tests. Sensitivity of the test method was comparable or better than other toxicity tests such as rotifer neonate mortality, bioluminescent bacterial inhibition, seaweed sporulation and sea urchin fertilization tests.
