초록
환경독성학(環境毒性學)(ecotoxicology) 관점(觀點)에서의 연구분야(硏究分野)는 크게 bioassay의 평가기법(評價技法)과 ecosystem analysis를 위한 야외조사(野外調査)로 대별(大別)된다. 본 연구(硏究)는 현재 다량(多量) 사용(使用)되고 있는 제초제(除草劑)(butachlor), 살충제(殺蟲劑)(carbofuran), 살균제(殺菌劑)(tricyclazole)를 철포(撤布)한 논에서의 periphyton에 대한 농약(農藥)의 영향(影響)을 평가(評價)하였다. 1) Periphyton 중(中) 기초생산자(基礎生産者)인 algae의 chlorophyll-a 함량(含量)은 벼 생육기간(生育期間)동안
There has been two kind of research fields in evaluating the ecotoxicity of chemicals The one is a bioassay and the other is an ecosystem analysis. The toxicants are transported into different biota, which have quite different environmental behaviour patterns and toxic properties. The effects of pesticides (butachlor, carbofuran, and tricyclazole) on periphyton community was studied by analyzing content of chlorophyll-a and autotrophic index (AI) that is a means of determining the trophic nature of the periphyton community. Results indicated that the content of chlorophyll-a was not influenced by the pesticides. The growth of algae was inhibited by sunshine period. And AI value is 43-2027: the large value indicates heterotrophic periphyton community, and was not affected by pesticides.
