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.

Research summary
تركزت الدراسة على تحديد تراكيز بعض العناصر المعدنية الثقيلة (النحاس، الكادميوم، الرصاص) في أنواع من الطحالب البحرية المنتشرة على شاطئ مدينة بانياس خلال عام 2014 باستخدام مطيافية الامتصاص الذري (تقانة اللهب). أظهرت النتائج أن تراكيز هذه العناصر تختلف باختلاف نوع الطحلب وموقع جمع العينات ومصادر التلوث. كانت تراكيز النحاس تتراوح بين 1.291 و 11.716 جزء في المليون، حيث سجلت أعلى قيمة في طحلب Enteromorpha linza وأدنى قيمة في طحلب Sargassum vulgare. أما بالنسبة للرصاص، فقد كانت أعلى قيمة 59.354 جزء في المليون في طحلب Enteromorpha linza وأدنى قيمة 6.46 جزء في المليون في طحلب Ulva fasciata. بالنسبة للكادميوم، سجلت أعلى قيمة 10.457 جزء في المليون في طحلب Ulva fasciata وأدنى قيمة 0.666 جزء في المليون في طحلب Enteromorpha linza. تشير النتائج إلى إمكانية استخدام الطحالب البحرية كمؤشر للتلوث بالعناصر الثقيلة، وخاصة طحلب Enteromorpha linza و Sargassum vulgare.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة لأنها تسلط الضوء على مشكلة التلوث بالعناصر المعدنية الثقيلة في البيئة البحرية وتأثيرها على الكائنات الحية. ومع ذلك، يمكن توجيه بعض النقد البناء للدراسة. أولاً، كان من الممكن توسيع نطاق الدراسة لتشمل فترات زمنية أطول ومواقع جغرافية أوسع للحصول على صورة أكثر شمولية. ثانياً، لم تتناول الدراسة تأثير هذه التراكيز على صحة الإنسان بشكل مباشر، وهو جانب مهم يجب أخذه في الاعتبار. ثالثاً، كان من الممكن استخدام تقنيات تحليلية إضافية لتعزيز دقة النتائج. وأخيراً، يجب أن تتضمن الدراسة توصيات واضحة للحد من التلوث وتحسين جودة المياه في المنطقة المدروسة.

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.
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 in dustrials 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.
This study deals with identifying some heavy metals (Pb,Zn,Ni) concentration in the recycledsewage in Latakia Countryside which is resulting from three treatment plants distributed over (Hebbeit, Al-Harah, MarjMoairban),2011.This research uses the El ectro Thermal Atomization-Atomic Absorption Spectrometry (ETA-AAS) technique in determining of heavy metal elements mentioned above. This research shows a higher concentration of Zn-element (2.798 mg/L) in all treatment plants and in all seasons compared with the concentration of other elements, while Ni and Pb have recorded low concentrations (0.351, 0.243) mg/ℓ, respectively. The statistical study has demonstrated that there is a correlation varying from positive high to positive low, and sometimes to negative highs and lows, this gives clear indications for resources of pollution.
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.
This study was conducted to determine some heavy minerals in different types of canned meat sold in the domestic market. Most of those cans were imported and processed in different countries and they have different brands. The chosen samples after ashing were prepared by using concentrated extra pure Nitric and Hydrochloric acids .The ratios of the minerals )pb , Cd , Ni , Zn , Cu , Mn , Fe ( were determined by Atomic Absorption Spectrophotometry , and the content was expressed as (p.p.m) wet weight. It was observed that the levels of Lead, Iron, and Cadimum, in all different samples were higher than the permitted limlts according to the Syrian Standards . The Cu level in both , tuna and sardine was within the permitted limits, but it was higher in the chicken Lunchoen. The level of Zinc was within the permitted limits according to the Syrian standards. The highest ratio of Lead was observed in the sardine imported from Morocco which was 8.765 p.p.m and in the Lunchoen processed in Syria which was 5.18 p.p.m ,and both ratios are much higher than the permitted limits according to the Syrian Standards.
