“…The concentration of TOC (%) in sediment is an important factor affecting PAHs concentration [51,61,62]. In current work, TOC (%) ranged (0.4%-2.2%) and the lowest values were recorded on Site 3 might be due to few human activities and lack of flow of sewage at this site throughout the study period.…”

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.

“…The values can be considered high and are in the same range as those of highly polluted systems in the northern Atlantic Ocean near Spain (1400 to 4900 ng g -1 ) (ANTIZAR-LADISLAO, 2009), the Huaihe River in China (60-2230 ng g -1 ) (FU et al, 2011), and the Santos Estuary, Brazil (15.400 ng g -1 ) (MEDEIROS and BÍCEGO, 2004). The clear predominance of high molecular weight PAHs (4-6 aromatic rings) over those of lower weight (2-3 aromatic rings) PAHs in all the samples analysed denotes pirolitic input (LIU et al, 2008). These inputs, from the incomplete combustion of fossil fuel are those which most persist in the environment (READMAN et al, 2002).…”

Integrated assessment of contaminants and monitoring of an urbanized temperate harbor (Montevideo, Uruguay): a 12-year comparisonSituated opposite the Freshwater Front, Montevideo city with its more than 1.5 million inhabitants encircles Montevideo Bay, where one of the most active and polluted harbors in South America is located. Faecal sterols, trace metals, organochlorine compounds and petroleum derivatives in the sediments of Montevideo Harbor were evaluated and their spatial distribution inside the harbor as well as in the input of two main tributary streams analyzed. Specifically for the harbor sites, a temporal comparison of metal and hydrocarbons was made with previous measurements taken 12 years ago. Clear changes were observed at these sites. The concentration of metals such as Pb, Cr and Zn have diminished, while aliphatic hydrocarbons have increased their values at almost all of the stations studied. Differences were observed between summer and winter suggesting sedimentation, input or hydrodynamic changes in the area. These results help one to understand the present situation and develop the management measures needed to improve the environmental quality of the harbor and bay. AbstrAct

“…They are often used as chemical markers to identify potential sources of environmental pollution from crude oil, gasoline and diesel (Froehner et al, 2012;Liu et al, 2008;Lee et al, 2005;Savinov et al, 2003;Yunker et al, 1999). PAHs can enter into the environment from different sources, which are primarily pyrolytic or petrogenic; biogenic sources are also possible.…”
