Determination of pesticide and naphthalene residues in eastern mediterranean honeys by LC/MS/MS and HS-SPME GC/MS

In this study, we aimed to determine the pesticide and naphthalene residues of 10 honey samples obtained from each of Adana, Hatay and Mersin provinces of Eastern Mediterranean region of our country. Honey samples were taken from the beekeeper units in the region. Pesticide screening in honey samples was pretreated by QuEChERS method and LC / MS / MS was performed. A total of 102 pesticide active substances were validated in the laboratory by LC / MS / MS before the analyzes. No pesticide was detected in all honey samples above the detection limit (LOD). Naphthalene analysis was performed by headspace solid phase micro-extraction (HS-SPME) GC / MS. Naphthalene was detected in one samples of the 30 honey samples. This value remained below the maximum residue level (MRL) of 10 ppb. In the two honey samples, the value was lower than the LOD level. According to results, the fact that honey in our country's Eastern Mediterranean region does not contain naphthalene and pesticides, is considered to be a very important finding for both consumers and the beekeeping sector
