为了研究强氯杀星、强力消毒粉、净水消毒清、卫康、顶点、金碘、速特、拜洁、高锰酸钾(KMnO4)、硫酸铜、硫酸锌、过硫酸钾、硫酸亚铁、氯化钠14种水产药物对东北林蛙蝌蚪毒性胁迫研究,试验在常温、静水条件下进行毒性试验。结果表明:KMnO4对东北林蛙蝌蚪24,48,72,96小时的半致死浓度(LC50)分别为3.297,2.684,1.512,1.098 mg/L,安全浓度(SC)为0.534 mg/L。KMnO4对东北林蛙蝌蚪属于中毒类药物(1.0 mg/L<96小时LC50<10.0 mg/L),KMnO4对东北林蛙蝌蚪不同时间的LC50与暴露时间呈正相关,且差异显著(P<0.05)。东北林蛙蝌蚪在卫康(1.0 mg/L)、顶点(0.1 mg/L)、强氯杀星(1.0 mg/L)、速特(0.1 mg/L)和硫酸铜(1.0 mg/L)溶液中24小时、48小时和96小时时的死亡率较高,东北林蛙蝌蚪在强力消毒粉(18.0 mg/L)、净水消毒清(18.0 mg/L)、金碘(500.0 mg/L)、硫酸锌(20.0 mg/L)、氯化钠(100.0 mg/L)、过硫酸钾(100.0 mg/L)和硫酸亚铁(100.0 mg/L)溶液中24小时、48小时和96小时时的死亡率较低。
In order to study the strong chlorine kill star, strong disinfection powder, water disinfection Qing, Wei Kang, the top, the gold iodine, special special, thanks to clean, potassium permanganate (KMnO4), copper sulfate, zinc sulfate, potassium persulfate, Iron, sodium chloride 14 kinds of aquatic drugs on the toxicity of tadpoles of Rana chensinensis northeast China, the test toxicity at room temperature, static conditions. The results showed that the LC50 of KMnO4 to tadpoles of Rana chensinensis were 3.297, 2.684, 1.512 and 1.098 mg / L respectively at 24, 48, 72 and 96 hours, and the safety concentration (SC) was 0.534 mg / L. KMnO4 was toxic to the tadpoles of Rana chensinensis (LC50 <10.0 mg / L at 1.0 mg / L <96 h), while the LC50 of KMnO4 at different times was positively correlated with the exposure time (P <0.05) . The results showed that the tadpole of Northeast Rana chensinensis was the best in the fields of Weikang (1.0 mg / L), apex (0.1 mg / L), strong chlorine kill star (1.0 mg / L) The mortality rate was higher at 24 h, 48 h and 96 h in the solution. Tadpole of Rana chensinensis had the highest mortality of 18.0 mg / L, 18.0 mg / L, 500.0 mg / L ), Zinc sulfate (20.0 mg / L), sodium chloride (100.0 mg / L), potassium persulfate (100.0 mg / L) and ferrous sulfate (100.0 mg / L) for 24 hours, 48 hours and 96 hours When the mortality rate is low.
