呋喃丹在模拟水稻-鱼和水稻-萍-鱼生态系统中行为归趋的比较研究

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 (14)C.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.
