Abstract/Description: | A liquid chromatography tandem mass spectrometry (LC–MS/MS) based method is reported for simultaneous analysis of fipronil (plus its metabolites) and difenoconazole residues in okra. The sample preparation method involving extraction with ethyl acetate provided 80–107% recoveries for both the pesticides with precision RSD within 4–17% estimated at the limits of quantification (LOQ, fipronil = 1 ng g−1, difenoconazole = 5 ng g−1) and higher fortification levels. In field, both the pesticides dissipated with half-life of 2.5 days. The estimated pre-harvest intervals (PHI) for fipronil and difenoconazole were 15 and 19.5 days, and 4 and 6.5 days at single and double dose of field applications, respectively. Decontamination of incurred residues by washing and different cooking treatments was quite efficient in minimizing the residue load of both the chemicals. Okra samples harvested after the estimated PHIs were found safe for human consumption. |
