用溴氰菊酯的工业品(纯度≥98%)以及常用的几种制剂进行了下列各项毒性试验。一、急性毒性试验溴氰菊酯急性毒性试验所选用的动物为大白鼠、小白鼠、兔、狗等,受试物是溴氰菊酯工业品,25克/升及15克/升乳油、10克/升超低容量喷布剂、2.5%可湿性粉剂、25克/升胶悬剂等。溴氰菊酯工业品对哺乳动物的急性毒性(见表7—1)。结果表明溴氰菊酯的急性毒性因动物种类、给药方式、溶剂种类等不同而异。不管溴氰菊酯通过何种途经给动物染毒,试验动物中毒症状基本相同,表现有运动失调、流涎、抽搐呼吸困难等,这是拟除虫菊酯品种所共有的中毒症状。根据世界卫生组织急性毒性剂量分级,溴
The following toxicity tests were carried out with commercial products of deltamethrin (purity ≥98%) and several commonly used formulations. First, the acute toxicity test deltamethrin acute toxicity test selected animals are rats, mice, rabbits, dogs, etc., the test substance is deltamethrin industrial, 25 g / l and 15 g / l EC, 10 g / l ultra-low volume of clothings, 2.5% wettable powder, 25 g / l plastic suspension. Acute toxicity of deltamethrin to industrial mammals (see Table 7-1). The results show that the acute toxicity of deltamethrin depends on the type of animal, the mode of administration, the type of solvent, and the like. Irrespective of the route of deltamethrin exposure to animals, symptoms of poisoning in experimental animals were basically the same with motility disorders, drooling and convulsions and breathing difficulties, which were symptoms common to pyrethroids. According to the WHO acute toxicity dose classification, bromine
