“…There is an obvious relation between PAH and TOC observed in the current study that indicates the positive relation between TOC and PAHs [62,63]. This relation might be due to many characterized of PAHs such as, tendency to organic compounds, anhydrous characters, or might be the fraction of TOC in the sediment [19,64].…”

Abstract:The Euphrates River is one of the major rivers in Iraq. When it reaches north of Hilla city, it will be divided in two branches. One of these braches flows toward Hilla city. On this branch, six locations were studied for the water quality of the Euphrates water. The present paper is aimed to fill the gap of information of the presence of PAHs (poly aromatic hydrocarbons) in water and sediment of Al-Hilla River, as well as to determine the quality and quantity of some PAHs. The depth of the river ranges from 2 m to 6 m. The quality, quantity and the origin of PAHs were studied in the water and sediment of Al-Hilla River. In addition, some physical and chemical properties were studied at six sites along the studied area, for the period March, 2010 to February, 2011. Sixteen PAHs that are listed by USEPA (US Environmental Protection Agency) as priority pollutants (Nap (naphthalene), Acpy ,h)anthracene), B(ghi)P (benzo(ghi)perylene) and Ind (indeno (1,2,3-cd) pyrene)) were detected in Al-Hilla river. High concentrations of PAHs were detected in the sediment relative to that within the water. The present study revealed that the origin of PAHs in water and sediment might be the pyrogenic origin.

“…This correlation explains the positive correlation between PAHs and clay, in contrast to this correlation, there was a negative and positive correlation between sand and some PAHs individual according to their adsorption and affinity between PAHs and sand [64,65].…”

“…Consequently, these chemicals can be ranked as petrogenic, pyrogenic or biogenic (Dahle et al, 2003). Petrogenic PAHs are related to combusted oil, coal and their by-products (da Silva and Bícego, 2010), and mainly comprised by 2 and 3-aromatic ring structures (Baumard et al, 1998), whereas in pyrogenic PAHs the "heavier" 4-6 ring molecules predominate, and their sources are primarily anthropogenic combustion processes (e.g.…”

The ability of pine needles to capture polycyclic aromatic hydrocarbons (PAHs) from the surrounding air is well known. In this work the current knowledge of this affinity will be enhanced, investigating the plausible links between the concentrations of PAHs found in pine needles collected in different sites in Portugal, and several socio-geographic variables with environmental relevance. Canonical correlation analysis (CCA) has proven to be a suitable and innovative technique to look for relationships within environmental datasets. In the current work, CCA will simultaneously include chemical information (concentration of PAHs found in pine needles) and socio-geographic information associated to the sampling areas. In order to be more robust in these conclusions, Pinus pinea and Pinus pinaster species were considered separately, allowing an accurate direct comparison between them. The information concerning the different seasons and land occupation was also taken into account. Our results demonstrate how CCA can be a useful tool in environmental impact assessment, and highlight the importance of pine needles as trustful biomonitors of the influence of socio-geographic parameters on the levels of PAHs in a given area.

“…In general, PAHs come mainly from two sources: petrogenic and pyrogenic. PAHs with four to six rings are derived generally from pyrogenic origin (Sanders et al, 2002;Dahle et al, 2003). Molecular indices based on the ratios of individual PAH levels in sediment can be used to assess the origin of PAHs.…”
