Dynamics of Cypermethrin Residue in Litchi Fruit and Soil

氯氰菊酯在荔枝和土壤中的消解动态


为揭示氯氰菊酯在荔枝中的消解动力学进行了荔枝田间试验.运用气相色谱仪测定了氯氰菊酯在荔枝土壤和荔枝中的残留量.两年的试验结果表明,氯氰菊酯在土壤和荔枝中消解迅速,在土壤和荔枝中的半衰期分别为8.6~9.60.0044~0.0165mg·kg-1(荔枝肉),均小于0.5mg·kg-1.

A field supervised experiment was conducted to reveal dynamics of cypermethrin in soil and litchi fruit,respectively.The residues of cypermethrin in soil and litchi were determined by gas chromatography.The results of two years‘ study showed that cypermethrin residues in both soil and litchi fruit disappeared rapidly under field conditions.Its half-lives in soil and litchi were from 8.6 to 9.6 days and from 10.4 to 16.4days,respectively.The final residues of the cypermethrin in soil and litchi at 7th or 10th day after last application ranged from 0.003 to 0.06 mg·kg-1 and 0.0044 to 0.0165 mg·kg-1(litchi pulp) which were less than 0.5 mg·kg-1.
