摘要
[目的]评价高效氯氟氰菊酯不同剂型对水生生物的毒性影响,为其科学合理应用提供依据.[方法]应用半静态法测试了10％高效氯氟氰菊酯微囊悬浮剂、2.5％高效氯氟氰菊酯EC、10％高效氯氟氰菊酯WP对斑马鱼的急性毒性效应.[结果]3种供试药剂对斑马鱼96h的LC50值分别为1.15×10-3、0.99×10-3、5.82×10-3 mg/L,95％置信限分别为0.81×10-3～1.48×10-3、0.81×10-3～1.15×10-3、3.24×10-3～7.89×10-3.[结论]依据《化学农药环境安全评价试验准则》,不同剂型高效氯氟氰菊酯对斑马鱼的急性毒性级别均为剧毒,毒性从高到低依次为2.5％高效氯氟氰菊酯EC、10％高效氯氟氰菊酯微囊悬浮剂和10％高效氯氟氰菊酯WP.
Abstract
[Objective] To evaluate the toxicity effects of different formulations of lambda-cyhalothrin on aquatic organisms,and to provide references for the scientific and reasonable application.[Method] Acute toxic effects of 10％ lambda-cyhalothrin microcapsule suspension,2.5％ lambda-cyhalothrin EC and 10％ lambda-cyhalothrin WP on zebrafish were detected by semi-static method.[Result] The LC50 values of three medicaments to zebrafish at 96 h were 1.15 × 10-3,0.99 × 10-3,5.82 × 10-3 mg/L,respectively;and the 95％ confidence limits were 0.81 × 10-3-1.48 × 10-3,0.81 × 10-3-1.15 × 10-3 and 3.24 × 10-3-7.89 × 10-3,respectively.[Conclusion] According to the Experimental Guideline for Environment Safety Evaluation of Chemical Pesticides,the toxicity of three formulations of lambda-cyhalothrin to adult zebrafish were highly toxic,which were in the order of 2.5％ lambda-cyhalothrin EC ＞ 10％ lambda-cyhalothrin microcapsule suspension ＞ 10％ lambda-cyhalothrin WP.
