The residue of

14

C-carbofuran in water was very low though the application rate was five times of that in the common case.Only a small part of the

14

C-residues in water were organic soluble products

in which most of them were carbofuran. The majority of

14

C-residues recovered in soil

fish and plant （cargo rice

husk

straw and roots） were unextractable （bound） and the percentages of bound residues were 86.55%

79.91% and 70.45%（73.26%

67.90%

64.22% and 76.41%）at harvest respectively The bound residues could be hydrolysed with HC1

and released significant amounts of the bound

14

C. The percentages of

14

C released from fish cargo rice

straw

roots

husk and soil at harvest were 91.60%

82.13%

30.47%

24.69%

18.67% and 17.30% respectively. Tne organic soluble portion of the

14

C released in all items analysed were small

and in which

the parent compound carbofuran was found as the greatest in quantity and decreased with time

next came to 3-hydroxy-carbofuran

3-keto-carbofuran and others （unknown） for soil.

14

C in hydrolysed soil could be further released under high temperature distillation （330℃

500℃ and 750℃）. Percentages of

14

C released were 21.44% to 28.49%30 to 76 days after the treatment

among which

the majority was organic soluble

14

C at 330℃

while

14

CO

2

was predominant at 500℃ and 750℃.
