Coriander and mustard floral honey samples collected form Rajasthan State of India were analyses for 27 organochlorine and organophosphorus pesticides residues. An analytical procedure based on QuEChERS extraction with acetonitrile followed by gas chromatography-mass spectrometry was used and samples were analysed on GC MS/MS Triple quadrupole System (Shimadzu TQ 8037). The calibration curves constructed were linear over the range from 0.005-0.025 Âµg ml-1. The correlation coefficient was â‰¥ 0.995 for all pesticides standard. The mean recoveries for extractions were 65- 115% for lower concentration range (0.005 mg kg-1
) and 70-120% for the higher concentration range (0.10 mg kg-1
) for pesticides analysed.
Three different pesticide, Dimethoate, Methyl parathion (organophosphate pesticides) and alpha- Endosulfan (organochlorine pesticides) were detected more than 0.001 mg kg-1 in coriander floral honey samples while in mustard floral honey samples Methyl parathion Famphur (organophosphate pesticides) and Eldrin Aldehyde were detected more than 0.001 mg kg-1 rest of pesticides were either not detected or detect below than 0.001 mg kg-1.
The study reveals that coriander and mustard floral honey produced from Rajasthan, India do not contain pesticide residue and safe for human consumption.
