The present study aims to quantifying and assessing the orgasmic and
Inorganic pollutants extents along eastern side of the United Arab
Emirates UAE offshore on the Gulf of Oman, which consist of Fujairah,
Khor Fakkan and Kalba. Rapid development and the highly usage of the
coastal region for industrial activities, sewage disposal and marine
transportation has led to obvious changes in sediments quality of the
marine environment. Twelve coastal sampling stations were selected to
cover the maximum area of the eastern side, three sampling stations were
selected from marine sediments and six sampling collected from spilled
oil near investigated area.
Sediments samples were subjected to a variety of analyses including
mechanical, total organic carbon (TOC), total petroleum hydrocarbon
(TPH), total kjeldahl nitrogen (TKN), twenty congeners of
polychlorinated biphenyl's (PCBs ), sixteen different polycyclic aromatic
hydrocarbons (P AHs) and heavy metals analyses
The grain size analysis showed that about 42 % of the studied stations are
covered by medium sand and 33% covered by fine sand, which reflected
trend of increasing the organic and inorganic pollutants by decreasing
grain size. The average TOC % analyzed in the study area is 0.6 % which
higher value than other regional studies. The average TPH in study area is
around 156 mg/kg. The total concentration of TKN in ranged between
83.8 mg/kg to 1443 mg/kg. This study indicates positive correlation
between TKN and TOC, which may be related to land pollution such as
industrial areas and agricultural pollution. The distribution maps of TOC
and TPH shows trend of an increasing toward the northern part of study
area whereas, TKN showed a trend of increasing toward the southern part
of study area.
The total concentration of PCBs in the study area was found to range
between 0.06 mg/kg to 0.145 mg/kg. The distribution maps of TPCBs
show increasing toward the northern part of study area KhorFakkan.
The total PAHs concentration in sediment samples ranges between 0.07
mg/kg to 0.28 mg/kg, in contrast the total concentration of PAHs from oil
sample was between 44.28 mg/kg to 299.3 mg/kg. The distribution maps
for each of compounds show two trend of increasing, in which one
toward the southern and another toward northeast of study area.
Nine heavy metals elements have been analyzed in this study i.e. Cd, Cr,
Cu, Co, Mn, Ni, Ph, V, and Zn. The highest detected concentrations are
Ni and Mn with average of 398.4 mg/kg and 191.4 mg/kg respectively.
The lowest determined concentration is Cd with average of 0.24 mg/kg.
In general, the heavy metals concentrations in the study area are low
compared to previous studies in the region.
