4种有机硅表面活性剂对斑马鱼的急性毒性与安全评价

Acute toxicity and safety evaluation of four organosilicon surfactants to zebrafish

为了评价新型有机硅表面活性剂对水生生物的影响,采用"半静态法",分别研究了"速渗1号"(SUSHENYIHAO)、"好湿"(High-Speed)、"杰效利"(JIEXIAOLI)及"捷润"(JIERUN)4种新型有机硅表面活性剂对斑马鱼的急性毒性,并进行了环境安全评价。急性毒性结果表明:"速渗1号"、"好湿"、"杰效利"及"捷润"对斑马鱼的LC50值(96 h)分别为135.0,17.4,11.3和5.9 a.i.mg/L,即前3种有机硅表面活性对斑马鱼毒性表现为低毒,"捷润"为中毒。

In order to assess the effect of organosilieon surfactant as a novel adjuvant for agroehemieal to aquatic organisms, the acute toxicity of four organosilicon surfactants ＂SUSHENYIHAO＂, ＂High-Speed＂, ＂JIEXIAOLI＂ and ＂JIERUN＂ were studied by semi-static method using zebrafish （Braehydanio rerio ） as test organism. Safety evaluation has also been conducted. The results showed that the LC50 value of ＂SUSHENYIHAO＂, ＂High-Speed＂, ＂JIEXIAOLI＂ and ＂JIERUN＂ to zebrafish in 96 h were 135.0, 17.4, 11.3 and 5.9 a.i. mg/L, respectively. The acute toxicity of ＂SUSHENYIHAO＂, ＂High-Speed＂ and ＂JIEXIAOLI＂ were low toxicity. The acute toxicity of ＂JIERUN＂ was middle toxicity.
