چکیده

abstract polycyclic aromatic hydrocarbons (pahs) are classified as persistent and carcinogenic organic pollutants. pahs contamination has been reported in water. many of relevant regulatory bodies such as eu and epa have regulated the limit levels for pahs in drinking water. in this study, 13 priority polycyclic aromatic hydrocarbons (pahs) were determined in tap water samples of tehran and water for injection. dispersive liquid-liquid microextraction procedure combined with gas chromatography-mass spectrometry was used for the extraction and determination of pahs in the samples. under the optimized conditions, the range of extraction recoveries and relative standard deviations (rsds) of pahs in water using internal standard (anthracene-d10) were in the range of 71-90% and 4-16%, respectively. limit of detection for different pahs were between 0.03 and 0.1 ngml-1. the concentration of pahs in all tap water as well as water for injection samples were lower than the limit of quantification of pahs. this is the first study addressing the occurrence of pahs in water for injection samples in iran using dispersive liquid-liquid microextraction procedure combined with gas chromatography-mass spectrometry.
