무당개구리 (Bombina orientalis) 배아의 발생에 제초제 Alachlor과 살충제 Endosulfan이 미치는 영향

초록

The chloroacetanilide herbicide alachlor and organochlorine insecticide endosulfan are the highly toxic agricultural chemicals. Bombina orientalis is one of the most common amphibians in the world and comprises a large proportion of their total number. We examined the embryotoxic and survival effects of alachlor and endosulfan at various concentrations in B. orientalis embryos. The survival rates of embryos at 312h post fertilization treated with alachlor and endosulfan were decreased with concentration dependent manner. Also, developmental malformations appeared by alachlor and endosulfan in B. orientalis embryos. These results suggested that alachlor and endosulfan were detrimental for survival and development of B. orientalis embryos.
