Polycyclic aromatic hydrocarbons (PAHs) were measured in soil samples, which collected for the period from January to August 2017, in Baghdad city, at AL-zubaidiya Thermal Power Plant. Soil samples were extracted by the soxhlet apparatus using mixture of acetone and hexane (1:1), and analyzed by GC/FID apparatus.The results show that the sixteen polycyclic aromatic hydrocarbon concentrations were varied in the two seasons. The most abundant compound in winter was naphthalene, while in summer season were naphthalene, acenaphthene, fluorene, pyrene and benzo[a]anthracene. The distribution of PAHs that have different aromatics ring, where the 2-rings are dominant in the winter season, while 2-rings, 3-rings, 4-rings are exists in summer season.
:The concentrations of 16 polycyclic aromatic hydrocarbons (PAHs) were determined in aerosol samples, which collected for the period (April 2012 to February 2013) at three sites in Baghdad city (AL-Daura refinery, ALDaura power plant and thermal power plant South of Baghdad). These aerosol samples undergone soxhlet extraction.After the extraction, 138 samples were analyzed by GC-MS to determine sixteen PAH compounds. The average concentrations of individual PAHs were measured in ambient air at the various season. The results indicate the spread of most of the sixteen PAHs at three sites in Baghdad city. Effect of sampling locations, seasons and meteorological conditions on the concentrations of PAHs were studied by SPSS. The positive correlation between the temperature and the total PAH concentration was varied in seasons, which indicated the existence of extrusive relationship between temperature and the total polycyclic aromatic hydrocarbon (TPAH) in the chosen sites.
Sixteen polycyclic aromatic hydrocarbons (PAHs) concentrations were measured in aerosol samples collected for the period from April 2012 to February 2013 at thermal south power station of Baghdad. Fourty one aerosol sample were extracted with (1:1) dichloromethane and methanol using soxhlet for seventeen hour. The extraction solution was analyzed applying GC/MS. The PAH concentrations outside thermal south power station were higher than those inside it, and higher in summer season than in winter. Naphthalene, pyrene, Anthracene, Indeno [1, 2, 3-cd] pyrene and Phenanthrene were the most abundant PAHs detected in all points at the site sampling. The total polycyclic aromatic hydrocarbon (TPAH) and total suspended particles (TSP) concentrations were measured during the measurement period. For individual PAH compounds, the results showed a strong correlation with each other (0.998 - 0.77) at both sites.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
