本文报道具有鼠、蟑兼灭性能的新型热烟雾剂鼠虫净的毒效及其残留物的安全性试验结果：①施烟空间密闭作用３０ｍｉｎ，对小白鼠的ＬＣ５０及其９５％置信限为１．０（１．４～１．９）ｍｌａ·ｉ／ｍ３，回归方程为Ｙ＝３．６＋６．５ｘ；对大白鼠和德国小蠊的毒性均比小白鼠大得多。②将鼠料放入试验空间，喷入对小白鼠全致死剂量药液密闭作用４０ｍｉｎ，通风排烟１ｈ后取出鼠料，给１６只正常小白鼠连续吃１５ｄ，所有试鼠无任何不适反应。③将５只恒河猴放入排烟１ｈ后的施烟空间连续３ｄ。之后移到饲养房再观察１５ｄ，定期测定生理指标（体温、呼吸、心率）、血液学指标（ＲＢＣ、ＷＢＣ、Ｈｂ、ＰＬＴ）和血液生化指标（ＧＯＴ、ＧＰＴ、ＡＬＰ、ＣｈＥ、ＢＵＮ、Ｃｒｅａ），测得数据与暴露前的正常值相比，除ＣｈＥ外差别均无显著性；ＣｈＥ活性在暴露后第１ｄ受到抑制，第３ｄ抑制开始缓解，第６ｄ其活性基本恢复到正常水平。④通过两种途径考核鼠虫净防制列车鼠类和蟑螂的效果，共试验６７辆车厢，分属于广州、柳州、北京和沈阳４个铁路局。结果人工放置靶子动物试验，７１０只德国小蠊全死亡；３０８只鼠的毒杀率为９５．５％；客车本身害鼠平均杀灭率７８．５％，害蟑平均杀灭率９８．５?
In this paper, we report the net toxic effects and the safety tests of the residues of the new hot aerosol agent pest insects with cockroach, cockroach and extinction properties: ① The confinement effect of smoking is 30min, the LC50 and 95% confidence limits 1.0 (1.4 ~ 1.9) mla · i / m3, the regression equation was Y = 3.6 + 6.5x; the toxicity to rats and German cockroaches were much greater than that of mice. (2) The rats were placed in the test space and injected with the lethal dose of the mice for 40 minutes. Ventilation and smoke exhausting for 1 hour was used to remove the rat materials. Sixteen normal mice were continuously eaten for 15 days without any discomfort. ③ put 5 rhesus monkeys into the smoke after 1h smoke space for 3d. (RBC, WBC, Hb, PLT) and blood biochemical parameters (GOT, GPT, ALP, ChE, BUN and Crea) were measured regularly. Compared with the normal value before exposure, the difference was not significant except for ChE. The activity of ChE was inhibited on the 1st day after exposure, and the remission on the 3rd day was relieved. The activity returned to the normal level on the 6th day. ④Through two ways to examine the effect of pest control on train mice and cockroaches, a total of 67 vehicles were tested, belonging to 4 railway administrations in Guangzhou, Liuzhou, Beijing and Shenyang. Results All the 710 German cockroaches were killed by artificial placement of target animal test. The poisoning rate of 308 mice was 95.5%. The average killing rate of passenger rats was 78.5% and the average killing rate of cockroaches was 98.5 ?
