This study was conducted in the Syrian coastal region, and the honey samples have
been collected from eight different sites belonging to the provinces of Latakia and Tartous
during the autumn of 2012. Their content of heavy metals (zinc, copper, le
ad & cadmium)
was estimated by Atomic Absorption at the Higher Institute for Environmental Research at
Tishreen University. The results showed that zinc concentration in the bee honey samples
ranged from 2.86 to 12.64 mg / kg (mean 7.98±3.67), and copper ranged from 0.125 to
0.652 mg / kg (mean 0.328±0.176 ), lead ranged from 0.084 to 0.378 mg / kg (mean
0.205±0.112), cadmium ranged from 0.0002 to 0.0132 mg / kg (mean 0.0053±0.0052). The
results indicated that the largest amounts of heavy metals were found in honey sample
taken from the apiary which is located at the eastern entrance of Latakia city (near Joud
factory), while the lower concentrations of zinc and lead were in Banias area (Wadi Al
Saqi), and the least concentration of copper was in Safita area, and of cadmium was in the
Gablah area (Bani Qahtan Castle).Comparing elements concentration in the studied honey
samples, Zinc concentration was found to be the highest, followed by copper, lead and then
finally cadmium.The results of statistical analysis indicated the existence of significant
differences between the studied sites during the autumn of 2012.
The aim of this study isto determinat the concentration of (Pb, Cu, Cd, Co, Cr , NiZn,
Fe) in storm water and their content of sediments during four seasons, the samples were
collected in four areas along Tartous beach. After make necessary treatme
nt concentrations
of elements determination by flame atomic absorption spectrometry.The results showed a
high levels of elements iron and zinc, in stormwater (138.6 μg/l - 99.7 μg/l) and sediments
(17.863 μg/l – 138.735 ppm), in all samples and there were concentrations another
elements difference between stations and rainfalls related to the human activities.
This study aims to determine the concentrations of some heavy metals that are present in the crude oil and in liquid waste of the crude oil desalting unit .The extraction method (liquid-solid) is used for concentrating and extraction these compounds
from the
saltwater samples .Samples were collected from the unit’s discharging points and from the subsequent treatment stages .A suitable analytical method was used to extract these metals
from both of crude oil and the oil refineries᾿ liquid wastes.
The objective of this study is to observe the fate of these wastes from the discharging points of desalting unit and through physical – chemical – biological treatment stages and dawn to the receiving water (Mediterranean sea). The results showed that Syrian crude oil contains a combination of heavy metals which includes : (Vanadium – Nickel – Iron – Zinc – Manganese – Copper – Cadmium – Lead - Chromium and Cobalt) .Vanadium showed the highest concentration followed by Nickel and Iron subsequently ,the total efficiency of the treatment plant achieved the following efficiencies : 41.06% (Vanadium), 44.92% (Nickel) and 39.34% ( Iron) ,then the concentration of these discharges where compared with those in marine system to show the possible adverse effects of these compounds on the surrounding biosphere.
