“…In strawberries the half-life value of carbofuran is 3.10 days. [13] The more rapid breakdown of carbofuran then carbaryl under tea field conditions can be recognized as a desirable chemical characteristic. Differences between residues of carbofuran and carbaryl on fresh tea leaves are due to the different physical and chemical properties of pesticides.…”

Carbofuran (2,3-dihydro-2,2-dimethyl-7-benzofuranol-N-methylcarbamate) and carbaryl (1-naphthyl-N-methylcarbamate) are insecticides widely used in tea plantations. The objective of the present study was to evaluate the dissipation of carbofuran and carbaryl during the growth periods of Oolong tea, processing and roasting. Analysis of the residual insecticides was carried out using high-pressure liquid chromatography with a post-column fluorescence detector. Results showed that in the tea field carbofuran dissipated faster then carbaryl. Manufacturing processes of Oolong tea further reduced the carbofuran and carbaryl contents. The persistence of carbofuran and carbaryl was decreased with increasing roasting temperature. From the results, we conclude that the presence of carbofuran and carbaryl in tea can be reduced by proper field management, manufacturing and roasting processes.

“…Methods usually employed for the determination of carbofuran in different matrices involve the use of chromatographic techniques. Gas chromatography has been employed both for the direct analysis of carbofuran2–7 and also after a previous derivatization step to obtain high temperature‐resistant compounds 8–10. Liquid chromatography has been frequently used with11–20 or without21–27 post‐column reaction detection for the determination of carbofuran.…”

Determination of carbofuran in pesticide formulations by flow injection spectrophotometry

A¯ow injection spectrophotometric method for the determination of carbofuran in commercial pesticide formulations was developed. The determination involves on-line hydrolysis of the extracted carbofuran at room temperature with sodium hydroxide. The resulting carbofuran-phenol is coupled with diazotized 4-aminobenzoic acid in order to achieve an appropriate selectivity and sensitivity for the spectrophotometric measurements. The calibration curve is linear over the range 1± 10 mg litre À1 of carbofuran. The proposed method has a detection limit of 0.15 mg litre À1 of carbofuran and a sample frequency of 120 injections per hour. The relative standard deviation of six independent determinations of a sample containing 1 mg litre À1 carbofuran was 0.6%. The suitability of the proposed procedure for the determination of carbofuran in commercial pesticide formulations was studied. The procedure provides results comparable to those obtained by liquid chromatographic analysis.
