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.
During the study of Molluscs/Cephalopods and their diversity and distributionin the
Syrian marine waters; the presence of squid Ommastrephaes bartramii has recordedfor the
first time locally, three individuals were collected during March and April
of 2016,
twoindividuals from the Ras Al-basset coast and one from Jablehcoast, at depths ranging
from 40-130m, the required morphometric were done.mantle lengths has ranged from 36.6
to 50.3 cm and 12,1-19cm widethe, fin is in the size of 17,3-23,3cm,and 14,3- 16 cm wide,
the proliferative arm is in the range size of 46.5 to 73 cm long. the individuals weights
vary between 2555,80-3954g. Anatomy of the samples was performed also. The gonad
vary between 20,6-41,12g, and the digestive gland weight ranged between 86,68-102,25g,
has been observed all of the three individual were females..
We screening for antimicrobial substances production from marine algae of
Syria. We presented results of ١٦ algal species tested by their lipide and
aqueous extracts agaimst Gram’s negative and positive bacteria, as well as one
fungous species.
T
he lipide not aqueous extracts were the active against Gram’s positive
bacteria especially.
No effect founded on the fongous species. In addition we make comparative
viewing with other studies on other mediterranean contries regarding the same
species of algae tested.
SST satellite images analysis has showed many
characteristics for a lot of mesoscale eddies in the Eastern basin
of the Mediterranean Sea. In this study, the SST analysis is
focalised on the mesoscale eddies` formation at the Syrian coasts.
We are also interested by their characteristics for their influences
on the marine environment .
