Polycyclic Aromatic Hydrocarbons (PAHs) in Muscles of Two Commercial Fish Species from Al-Kahlaa River in Missan Governorate, Iraq
Abstract: 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.
