This paper aimed to present the first record of Pterois miles (Bennet, 1828) off the
Syrian coast (Eastern Mediterranean). Two specimens (159; 206 mm SL) were captured in
Syrian waters between Lattakia and Jableh in 28th September 2015 and 10th Dec
ember
2015. This first record of common lionfish Pterois miles in the Syrian coast could confirm
the occurrence of this species in the Levant Basin (eastern Mediterranean). This is the fifth
record of the species reported to date in the region. These records are not sufficient to state
that the species is substantially established in the area, but investigations are rapidly
needed to avoid unfavorable consequences on local environment and economy.
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.
Proteus volgaris was isolated from costal sea water of Lattakia city port, as it is contaminated with petroleum compositions coming from marine transportations activities. The ability of this bacteria to degrade the petroleum alkanes was studied by
using different concentrations of petroleum as sole source of carbon and energy. The gas chromatography (GC) technique was used to measure the concentration of alkanes. Results showed that the isolated bacteria were able to degrade different alkanes chains. The ratio of biodegradation of C12, C16, C18 were 96.75%, 78.59%, 97.27% respectively, while the rate of biodegradation of the entire amount of alkanes was 77.14% in 10 mg/ml polluting concentration. The percentage of biodegradation at concentration 75 mg/ml of petroleum was 17.26%.
Therefore, the high ability of Proteus volgaris to degrade the long chains alkanes recommended it to be effective in the bioremediation process of the contaminated marine environments.
