【摘要】 １９９７年６～８月，通过人工控制ＮＨ３－Ｎ及ＮＯ２－－Ｎ的浓度，对欧洲鳗鲡进行急性毒性试验的结果表明：非离子态氨对欧洲鳗鲡２４、４８、９６ｈ的半致死浓度分别为４．２６、３．２７、２．１９ｍｇ／Ｌ，安全浓度为０．２１９ｍｇ／Ｌ；亚硝酸盐对欧洲鳗鲡２４、４８、９６ｈ的半致死浓度分别为１００．０、８４．１、２６．６ｍｇ／Ｌ，安全浓度为２．６６ｍｇ／Ｌ。更多还原

【Abstract】 Tests on acute toxicity of ammonia and nitrite to european eel were conducted by concentration controlling during the period of June to August, 1997. The results showed that 24, 48 and 96 hours LC50 of ammonia to the eel were 4.26, 3.27 and 2.19 mg/L respectively, and its safe concentration was 0.219 mg/L. Those of nitrite to the eel were 100.0, 84.1 and 26.6 mg/L respectively with a safe concentration of 2.66 mg/L.更多还原
