The present study was performed to have knowledge of Polycyclic Aromatic  Hydrocarbonspollution status in water. The samples were collected during two seasons (winter and summer 2012 ,2013) from four different stations) Al-Magideh, Treatment unit, Al-Husaichi and Al-Zubair) distributed along Al-KahlaaRiver in Missan province, in addition to reference station lies on the Tigris river before  25 Km  from entering to Amara city. The concentrations of PAHs were determined in by using capillary Gas Chromatography. Results of the present  study revealed that the total concentrations of PAHs  in dissolved fraction  ranged from 0.739 ng.l-1 in Reference station to 1.974 ng.l-1 in Treatment unit during winter, and from 0.300 ng.l-1 in Reference station to 1.125 ng.l-1 in Treatment unit during summer, while in the particulate fraction they varied from 0.79 ng.g-1 dry weight in Reference station to 24.42  ng.g-1 dry weight in Treatment unit during winter, and from 4.369 ng.g-1 dry weight in Reference station to 10.545 ng.g-1 dry weight in Al-Husaich during summer. It had been noticed that there were a predominance of high molecular weight PAHs on low molecular weight, while  BaA/(BaA+Chr) ratio in water ranged from 0.218 to 0.804. InP/(InP+BghiP) ratio ranged between 0 and 0.578,whereas Fl/Pyratio ranged between 0.150 and 2 ,this give an indication of  the origin  of PAHs compounds in water which were mainly pyrogenic and few from them  petrogenic.

Al-Kahlaa River is one of main tributaries of the Tigris River in Missan city and rises from northwest side of Amara city and continues to flow in the direction to the east of city center. Two commercial fish species (Liza abu and Carassius auratus) were collected seasonally (autumn, winter, spring and summer) during period from 2012 to 2013 from Al-Kahlaa River in Missan governorate. The concentrations of Polycyclic Aromatic Hydrocarbons (PAHs) in fish muscles were determined in the laboratories of Nihran Omer (South Oil Company in Basrah province), using Gas Chromatography. Total concentrations of PAHs in muscles of L. abu ranged between 2.301 and 16.661 ng.g-1 dry weight during winter and summer respectively and in C. auratus between 1.095 and  8.675 ng.g-1 dry weight during winter and summer, respectively. Results of this study revealed that high molecular weight of PAHs were more than low molecular weight in both fish species, and according to ratios of Low molecular weight Polycyclic Aromatic Hydrocarbons (LPAHs) to High molecular weight Polycyclic Aromatic Hydrocarbons (HPAHs), Benzo(a) Anthracene /(Benzo(a) Anthracene+ Chrysene) BaA/(BaA+Chr),Indeno (1,2,3-cd) pyrene /(Indeno (1,2,3-cd) pyrene + Benzo (ghi) perylene) InP/(InP+BghiP) and Fluoranthene/Pyrene (Fl/Py), they certainly reflected that the PAHs sources in both species are pyrogenic as a main sources  and petrogenic as a small part. Also results of this study revealed the presence of seasonal variations in total concentrations of   PAHs in both fish species. The study area was generally contaminated with hydrocarbons and continuous consumption of food from this area may pose public health hazards. Keywords: polycyclic aromatic hydrocarbons, PAHs, fish, pollution Al-Kahlaa adalah salah satu anak sungai utama Sungai Tigris di kota Missan dari sisi barat laut kota Amara dan terus mengalir ke arah ke timur dari pusat kota. Dua spesies ikan komersial (Liza abu dan Carassius auratus) diperoleh pada musim berbeda (gugur, dingin, semi dan panas) selama periode 2012-2013 dari Al-Kahlaa. Konsentrasi polisiklik aromatik hidrokarbon (PAH) pada otot ikan dianalisis di laboratorium Nihran Omer (South Oil Company di provinsi Basrah), menggunakan Gas Chromatography. Total konsentrasi PAH pada otot L. abu berkisar antara 2,301 dan 16,661 ng.g-1 berat kering pada musim dingin dan musim panas. Sedangkan pada C. auratus antara 1,095 dan 8,675 ng.g-1 berat kering pada musim dingin dan musim panas. Hasil penelitian ini menunjukkan bahwa berat molekul tinggi PAH lebih dari berat molekul rendah pada kedua spesies ikan, dan menurut rasio berat molekul rendah polisiklik aromatik hidrokarbon (LPAHs) untuk berat molekul tinggi polisiklik aromatik hidrokarbon (HPAHs), Benzo (a ) Anthracene / (Benzo (a) Anthracene + Chrysene) BAA / (BAA + Chr), Indeno (1,2,3-cd) pyrene / (Indeno (1,2,3-cd) pyrene + Benzo (ghi) perylene) InP / (InP + BghiP) dan fluoranthen / Pyrene (Fl/Py), hal ini mencerminkan bahwa sumber PAH di kedua spesies adalah pirogenik sebagai sumber utama dan petrogenic sebagai bagian kecil. Hasil penelitian ini juga mengungkapkan adanya variasi musiman total konsentrasi PAH di kedua spesies ikan. Daerah penelitian umumnya terkontaminasi dengan hidrokarbon sehingga konsumsi makanan dari daerah ini secara berkelanjutan dapat menimbulkan bahaya kesehatan masyarakat.

The reconstruction of fire history is essential to understand the palaeoclimate and human history. Polycyclic aromatic hydrocarbons (PAHs) have been extensively used as a fire marker. In this work, the distribution of PAHs in Borneo peat archives was investigated to understand how PAHs reflect the palaeo-fire activity. In total, 52 peat samples were analysed from a Borneo peat core for the PAH analysis. Pyrogenic PAHs consist of 2–7 aromatic rings, some of which have methyl and ethyl groups. The results reveal that the concentration of pyrogenic PAHs fluctuated with the core depth. Compared to low-molecular-weight (LMW) PAHs, the high-molecular-weight (HMW) PAHs had a more similar depth variation to the charcoal abundance. This finding also suggests that the HMW PAHs were mainly formed at a local fire near the study area, while the LMW PAHs could be transported from remote locations.

Based on field data of polycyclic aromatic hydrocarbons (PAHs) in water and sediment in Nansi Lake. The concentrations and the partitioning characteristic of PAHs in the water and sediment were studied. The lgKd of high molecular weight PAHs were higher than the low molecular weight PAHs. The most of PAHs Kd values were negligible correlated with TOC, soluble salt, clay and pH of the sediment in Nansi Lake.
