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.
Concentrations of eight chlorinated pesticides: namely, gamma HCH, Heptachlor,
heptachlore epoxide, aldrin, dieldrin, 4,4-DDE, 4,4-DDD, and 4,4-DDT were studied in
some mollusks species Monodonta turbinata, Brachidontes variabilis , Patella caerule
a,
Trochus erithraeus, Strombus persicus and in sediments taken from five different
locations: Assin estuary, Jobar estuary, Banias Thermal Electricity Station, Albasia, and
Mirkiya River estuary. Sampling was performed at six different times during the period
2006-2007.
Results indicated that Assin estuary contained the highest level of contamination
followed by Jobar estuary and Mirkiya estuary where sampled mollusks species contained
various concentrations of all of the studied pesticides. At Banias Thermal Electricity
Station samples showed contamination with heptachlore and heptachlore epoxide only,
whereas the concentration of pesticides at Albasia location, much lower than the other
locations.
Samples of surface sediment of St. Johns River Basin were collected,
extracted and their aliphatic hydrocarbons (AH) were determinated
quantitatively and qualitatively by GC-FID and GC-MS Techniques, were used
to characterize the (AH) hydrocarbons
homologous and biomarker
compounds.The sediments contained high organic matter content, while the
hydrocarbons AH represented ٠,٣٥-٢,٧٢٪ of the total organic matter (TOM)
found in sediments.
