In This study it has been uses a network for monitoring the pollution with organochlorine pesticides in There marine stations at Lattakia coast: Fishing port, AfamiaCoast, High Institute Of Marine Research Coastusing Cages contained species of musselswitch are filter feeders Brachidontes varibilis. Samples had been collected from Lattakia coast. The results showed a great efficiency of the made network for monitoring the organic pollution in marine environment. It has been recorded a concentration of DDTs is accumulated lower than 2ng/g , Endosulfane and HCB is lower than 1 ng/g too. The results showed that the HCH compounds is dominant in all stations.organochlorine pesticides is accumulated mostly in the biota of station Fishing port, Afamia Coast

The purpose of this study is to highlight on the ability of the alga Ulva fasciata to accumulate some organic pollutants (polycyclic aromatic hydrocarbons :PAHS, polychlorinated biphenyls: PCBs). The samples were collected from three sites at the Syr ian coast during 2011. The result of this study revealed the ability of alga to accumulate significantly the PAHs and their concentrations ranged from 30.52 to 72.7 ng/g dw, While the PCBs concentrations were less, it ranged between 6.00 and 24.01 ng/g dw. The highest concentration of PAHs was observed at the Dirasat site, while the highest concentration of the PCBs found at the Cornish of Jablah. The logarithm bioconcentration factors (log BCF) of the aromatic compounds with three aromatic rings were close to the logarithm octanol/water partitioning coefficients (log Kow ), unlike the compounds with higher rings, where log BCF were obviously less than corresponding log Kow. The log BCF values of PCBs increased with increasing chlorine atoms (2 - 6 atoms) , while no increasing was observed for components that contain 7 to 8 chlorine atoms
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.
This work was designed to investigate the effect of temperature of frozen storage and its duration on some chemical properties (Protein, Ash, Moisture,Lipid) of fishes Rabbit fish (Siganus rivulatus). The fishes were subjected (from one weak to 150 day) of frozen storage at two different degrees of low temperatures (-18 C,-24 C).
This review aims to show the techniques of lidar in atmospheric remote sensing, which can be utilized to draw three-dimensional maps of pollutants distribution over path lengths of the order of few kilometers. The detection limits achieve values o f the order of ppb. This sensitivity and accuracy gives this method its superiority over all other physical and chemical methods of detection. Some details of this method are given for the following pollutants: NO, NO2 , SO 2, O3, HCl, C2H4, benzene and toluene, as well as atomic mercury. This work shows, for these pollutants, absorption wavelengths, differential cross sections and detection limits. In addition to dealing with the technical requirements and different designs of Lidar. On the other hand, this review study handles the characteristics of many laser sources used in lidar systems such as, Nd:YAG- laser, Dye- laser and others. Especially it concentrates on pulse energy, time duration, repetition rate and nonlinear crystals, used for frequency doubling, which broaden the working region of the lidar.
Alsin Spring is the most important water sources in Syrian coastal area, due to it is the source of drinking water for the main cities and towns in the Syrian coast. This research aimed to study some contaminant indicators in Alsin spring and some t aps of distribution system of Alsin drinking water, and compare the Indicators with samples of bottled drinking water from Alsin spring and three other water sources (Drekish, Bukkeen, and Alfigeh). The study included determining the concentrations of nitrates, nitrites and some heavy metals including lead, cadmium and nickel in water samples. The results showed that all water sources contain varying concentrations of lead, while the nickel and cadmium were vary in drinking water samples; The concentrations of nickel and cadmium in some samples were low while were under the detection limits in other samples. The analysis of samples of bottled drinking water showed that the samples from Alfigeh spring were the lesser contamination with heavy metals, while the samples from Alsin spring were contain highest concentrations of lead and nickel. The samples of bottled water from Bukkeen spring contain the highest level of cadmium. The results showed that the concentrations of nitrate, nitrite and heavy metals differ depending on the water source. However, all these concentrations were lower and within the acceptable limits of Syrian standard for drinking water. The study concluded that water resources in the coastal area are distinguished with their higher pure.
