Survey some poly aromatic hydrocarbons (PAHs) accumulation in tissues of wild pigeon from Tehran megacity

Megacities like Tehran are polluted with some air pollutants including poly aromatic hydrocarbons (PAHS) released from fossil foil burning, which can influence on human and organism's health. The wild pigeon Columba livia is widely distributed in megacities and can be used as sentinel species, because of high metabolic rate, inhaling environmental pollutants as well as swallowing pollutants particles and their bioaccumulation. The PAHS with ۵ and ۶ rings like Benzo a pyrene and Benzo a anthracene are well recognized as toxic pollutants for genotoxicity, carcinogenicity and motagenicity. This study is aims to survey the level of some PAHs with ۵ and ۶ rings (BghiP, dAHa, IcdP, B(k)F, B(b)F) in rock pigeon (Columba livia) from Tehran megacity. The muscle, liver, kidney and skin were collected for PAHs analysis. Sample preparation and PAHs analysis were conducted with standard procedures. The concentrations of pollutants were carried out using Gas-chromatography mass-spectrometry (GC-MS). Data were subjected to one-way analysis of variance (ANOVA) and Tukey post-hoc and were employed to survey whether concentration varied significantly between tissues. The mean concentrations of PAHS were obtained ۱۳.۱۹, ۳.۷۹, ۴.۳۰ and ۳.۰۷ ng.g-۱ dw in muscle, liver, kidney and skin respectively. According to the finding, significant different were found between tissues and muscle had more concentration (p<۰.۰۵). Also, the same accumulation pattern (kidney≤liver
