摘 要:采用斑马鱼胚胎发育技术和传统毒理学方法,研究了氟吡菌胺对斑马鱼胚胎、成鱼及仔鱼的毒性效应.结果发现,氟吡菌胺对3个阶段斑马鱼均具有致死能力,对仔鱼LC50(48h)值为0.204mg/L,成鱼LC50(96h)为0.286mg/L,幼鱼LC50(96h)为1.489mg/L.研究表明,0.0596mg/L以上浓度的氟吡菌胺对斑马鱼胚胎均有一定程度的致死效应,高浓度处理组胚胎出现心包囊肿、卵黄囊不吸收、黑色素沉积少及鱼体弯曲等症状;氟吡菌胺对斑马鱼成鱼进行14d暴露后,处理组成鱼体重下降,产卵量减少,有效卵量降低;0.0298mg/L处理组144h子代仔鱼存活率虽然比较高,但存活鱼大部分出现心包囊肿、体弯曲等畸形.上述结果说明,水体中残留的氟吡菌胺对于斑马鱼各生命阶段的生长发育均具有潜在的危害.The zebrafish embryos technology and traditional toxicology methods were used to determined the toxicity of fluopicolide to zebrafish embryos、adult fish and larvae. Fluopicolide had lethal capabilities to the three stages of zebrafish with the LC50(48h) values to larvae and LC50(96h) to adult fish and juvenile was 0.204mg/L, 0.286mg/L and 1.489mg/L. 0.0596mg/L or more concentrations fluopicolide have a certain degree of lethal effect to zebrafish embryos, and the embryos which were treated with high concentrations displayed many of the symptoms, such as pericardial cyst, yolk sac does not absorb, less melanin deposition and fish bending. After 14days exposure with fluopicolide, the adult zebrafishs expressed the following symptoms:weight loss, reduction in fecundity, the amount of effective eggs were reduced;After treated by 0.0298mg/L fluopicolide, though 144h offspring larval’s survival relatively high, but most surviving fish has still emerged as deformity: pericardial edema and abnormal body bending, etc. Fluopicolide residue in water have the potential hazards to the growth and development of each life stage of zebrafish.
