• 摘要：用¹⁴C标记法研究呋喃丹在水稻-鱼和水稻-萍-鱼两种模拟生态系统中的分布、消失和残留行为。结果表明,由于萍的引入,使在水稻-萍-鱼系统中,田表水中的残留较低,而鱼体中残留较高。结合态残留物是土壤、鱼和植株体中呋喃丹的主要残留形态。

• Abstract：The distribution, the disappearance and the residue of carbofuran in rice/fish and rice/duckweed/fish ecosystems were studied after applying the chemical labeled with ¹⁴C.In the rice/duckweed/fish system, the content of carbofuran in paddy water was lower and in fish tissue was higher than that in the rice/fish system. It was found that the bound residues constituted a majority of the chemical residues in soil, rice plants and fishes.

• Key words：carbofuran  pesticide residues  bound residues  paddy soil  fish  rice
