Determine of some of heavy metal in Boops boops in the coastal water of Lattakia

This research focuses on determining elemental concentrations of copper and lead (Cu &pb) in the muscles and liver Boops boops kind of the estuary of the AL Kabeer Alshemaly River and the fishing port and the promenade using atomic absorption technique. The results showed a significant increase in the concentrations of lead during summer 2014 in each of the muscle tissue and the liver of the fish examined (28.28ppm& 4.48ppm, respectively) at the mouth of the estuary of the AL Kabeer Alshemaly River and the fishing port and the promenade (11.19ppm& 3.75ppm, respectively), and this could be due to the different nature of human activities and sources of pollution to this element between the two regions. The results showed a marked seasonal change in the concentration of copper within the liver tissue of fish studied, where the highest concentration in the fishing port and the promenade( 5630.02 ppm) in autumn 2014, the Supreme( 3402.27ppm) value in the AL Kabeer Alshemaly River the estuary of summer. While the results did not show the variable in concentrations of copper in muscle . Theconcentrations were comparable between the two stations somewhat, with the highest concentrations in the summer in Bouth the fishing port and the promenade 1497.70ppm) and(1107.91 ppm) the AL Kabeer Alshemaly River. Results indicate that the accumulation of the studied elements (Cu &pb) in the liver compared to muscle (and the reason is boiled physiological differences in the functions of each of the two members) and to the existence of a good correlation between the concentration in the muscle changes with the typical length of which points to increased accumulation of these elements in these fish with increased growth,Noting the high concentration of the studied elements in females more than those recorded in males.

Identify the most important factors that control Nickel and Cadmium dispersal in the recent sediments of Ras AL-Basit coast

This research focuses on determination the concentration of some heavy metal elements (Nickel Ni and Cadmium Cd) in the coastal water sediments of Ras Al-Basit (Latakia ) during the period that range between Autumn 2013 and Summer 2014 using the Atomic Absorption (Atomic Absorption Spectrophotometer: AAS) at two different (closed and open) geographical regions. The results of the research indicate a correlation monumental between the change in the concentration of studied metallic elements (Ni & Cd), the quality and sediment sampling sites on the one hand, and the sources of pollution on the other. It observed the rule of fine sand with minor amount of clay in the sediments collected from closed area; with high concentrations of both Nickel (755.50mg/Kg), and Cadmium (71.30μg/ Kg), compared with the open area while the majority of the sediments are medium sand with low Nickel and Cadmium concentrations (38.85mg/Kg; 13.31μg/ Kg).

Determination of the contents of some trace of Heavy metals (Cu, Cd, Pb) in marine algae from the coast of Banias

The study focused in this research to determine the trace of some heavy metal elements (Copper Cu, Cadmium Cd, Lead Pb) in some types of marine macroalgae scattered on the shore of the city of Banias during 2014, using atomic absorption spectroscopy (technology flame Flame- AAS). The results indicate that the concentrationsofeach of Copper, Cadmium and Lead have a link with macroalgae types, sampling sites from direction, and Source of pollution on the other hand; it was observed that the accumulation of heavy metals in both of Sargassum vulgare (browen algae) and Enteromorpha linza (green algae) was more than red algae. Copper concentration ranged between 1.291 ppm and 11.716 ppm in the studied species, Reaching the highest value in the Enteromorpha linzaalgae and the lowest in Sargassum vulgarealgae, the highest value of Lead element was (59.354 ppm) in Enteromorpha linzaand the lowest value of it was (6.46 ppm) in Ulva fasciata, While the highest values of the element Cadmium recorded (10.457 ppm) in Enteromorpha linza and the lowest (0.666 ppm) in Ulva fasciata.

Determination of some trace metals in the leaves and periderm of Avundodonax L. distribution in Lattakia city using Atomic Absorption Spectrophotmetry

The aim of this study was to determine the trace of some heavy metals elements pb, Cd, Cu, Zn & Fe in the leaves and periderm of the Avundodonax L. using Atomic absorption spectroscopy. The samples were collected from twenty locations and divided into four groups according to traffic and human activities. The results showed an excess in the concentration of lead, cadmium and copper in the leaves and periderm of the Avundodonax L., which enables the use of this plant as a vital indicator for the pollution by these heavy metals. The concentration of cadmium in the leaves and periderm ranged between (0.231- 6.278ppm) and for lead between(1.057- 47.592ppm) and copper between(1.022 -45.771ppm). While the concentration of both zinc and iron remained within the permissible natural limits.

Determination of some trace heavy metals in dust particles deposed on the leafs of some trees along Syrian coast

This study deals with the determination of the quantity of solid dust particles deposed on the leafs of some trees along Syrian coast and the concentration of some heavy metals in it (Zn, Fe, Pb, Cu, Ni, Cd, Co, Mn) .Some sites near to human and industrials activities , and others near to agriculture activities , and others relatively far from pollution sources has been selected. The results showed that the quantity of solid dust particles on leafs trees and concentration of heavy metals in it such as (Pb, Ni, Cd, Co) increasing near the industrials activities and dense traffic, and decreasing in the sites that relatively far from of pollution sources. However Cypress trees attach solid quantities more than Pride of china, following Rever red gum and Blue-leafed wattle and Oleander, and the Palm tree come in the last.

Determination of some trace metals concentrations in storm water on Tartous province coast

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 treatment 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.
