Abstract:

This research reports a validated multi-residue method based on gas chromatography coupled mass spectrometry technique for analysis of 24 Polycyclic Aromatic Hydrocarbons (PAHs) in traditional and semi-industrial Taftoon bread using QuEChERS sample preparation. Matrix effect studies were performed by comparing the slopes of solvent based standard calibration curves and spiked calibration curves. Due to enhancement or suppression effects of matrix, validation of the method was performed using spiked calibration curves. In the concentration range of 10-500 ng/g, the calibration curves for each analyte was linear with a determination coefficient (R2) of 0.991-0.999. The Detection and quantitation limits for the studied PAHs were calculated 0.14-1.49 ng/g and 0.46-4.91 ng/g. The average recoveries for three spiked levels (25, 50 and 200 ng/g), were in the range 77-103% (n = 27), with a satisfactory precision (RSD < 20%). Analysis of Taftoon bread samples using the validated method showed that three compounds; NPH, PHE and ANT were found in 37 (35.2%) samples and in the term of traditional and semi- industrial samples the occurrence of mentioned PAHs were 36.1% and 33.3%, respectively. According to the findings, we proposed that direct flame exposure in gas oven during baking of Taftoon bread could produce PAHs in bread samples.

Validation of an Analytical Method for Determination of 13 priority polycyclic aromatic hydrocarbons in mineral water using dispersive liquid-liquid microextraction and GC-MS

Dispersive liquid liquid microextraction (DLLME) combined with gas chromatography–mass spectrometry (GC–MS) was used for the extraction and determination of 13 polycyclic aromatic hydrocarbons (PAHs) in mineral water samples. In this procedure, the suitable combination of extraction solvent (500 µL chloroform) and disperser solvent (1000 µL acetone) were quickly injected into the water sample (...

Determination of particle-associated polycyclic aromatic hydrocarbons in urban air of Beijing by GC/MS.

Particle-associated polycyclic aromatic hydrocarbons (PAHs) collected in urban air of Beijing were studied using a gas chromatograph mass spectrometer (GC/MS). The average concentration of particle-associated PAHs measured in this work was in the range from 28.53 to 362.15 ng/m3, which suggested a serious pollution level of PAHs in Beijing. The results also showed that the concentration of PAHs...
