Analysis of pesticide residues in commonly consumed fruits in Mubi metropolis, Adamawa State, Nigeria


Alexander Priscilla

The present study was conducted to determine the pesticide residues in commonly consumed fruits (orange, mango and banana) in Mubi Metropolis. These fruits samples were collected from farms and local markets in Mubi Metropolis, Nigeria. Pesticides residues were extracted from the fruits using a quick, easy, cheap, effective, rugged, and safe (QuEChERS) method. Extraction of the samples was carried out using acetonitrile containing 1% acetic acid to determine the residual concentration of pesticides which may have been sprayed during seasonal growth. Gas chromatography/mass spectrometry (GC/MS) was used for quantitative and confirmatory analysis of the pesticides. The pesticides residue in fruits samples were determined and confirmed from their molecular weights. The molecular weights of pesticides were compared with that given in the data bank of GC/MS. The investigation showed that pesticides with low molecular weight were eluted before the high molecular weight pesticides. The factors studied were retention time, relative abundance and molecular weight. The following pesticides were identified during the analysis, dichlorvos, dichlorodiphenyltrichloroethane (DDT), Dieldrin, cyhalothrin and glyophosphate.
