【摘要】 研究氯化三丁基锡（ＴＢＴ）对摇蚊幼虫的毒性作用，结果表明，ＴＢＴ对红德永摇蚊幼虫（Ｔｏｋｕｎａｇａｙｕｓｕｒｉｋａａｋａｍｕｓｉ）４８ｈＬＣ５０为２８５．４μｇ／Ｌ；ＴＢＴ对羽摇蚊幼虫（Ｃｈｉｒｏｎｏｍｕｓｐｌｕｍｏｕｓｕｓ）２４ｈＬＣ５０为１６．６μｇ／Ｌ；１０ｄ中，ＴＢＴ浓度为２５μｇ／Ｌ时，红德永摇蚊幼虫的下唇板出现可观察到的畸变；４ｄ中，ＴＢＴ浓度为０．５μｇ／Ｌ时，羽摇蚊幼虫的下唇板出现可观察的畸变．ＴＢＴ对红德永摇蚊幼虫四齿幼虫１０ｄ化蛹的ＥＣ５０为９．９６μｇ／Ｌ．更多还原

【Abstract】 The toxicity of Tributyltin(TBT)to Chironomus larvae was studied.The results showed that the 48h LC 50 of TBT to Tokunagayusurika akamusi larvae was 285.4μg/L,the 24h LC 50 to Chironomus plumousus larvae was 16.6μg/L,the 10 days EC 50 of TBT to pupatoin of T.akamusi larvae was 9.96μg/L.In 10 days,at 25μg/L TBT,there was the deformity of mentum of T.akamusi larvae.In 4 days,at.0.5μg/L,there was the deformity of mentum of C.plumousus.更多还原
