This study aims to compare the ability of four plant species (Ficus benjamina L., Bougainvillea glabra, Ligustrum vulgare L., Bauhinia variegate Linn.) to absorb and accumulate the cadmium element which is basically emitted by motor vehicles (transportation). The four species were planted in Alfoursan Park in Lattakia City. Samples of leaves, bark, wood and soil were collected, and then processed (drying, digesting and filtrating) for analysis using an atomic absorption spectrophotometer. The results showed that the highest concentration of cadmium was in the bark of Bougainvillea glabra 4.4 ppm (in dry weight), next in the leaves of Bougainvillea glabra 4.2 ppm, then in the bark of Ficus benjamina L. 3.93 ppm, and finally in the bark of Bauhinia variegate Linn. 3.55ppm. The lowest concentration, however, was in the wood of Ficus benjamina L. 1.66 ppm. The results show the importance of the four species and the potential of absorption and accumulation of the cadmium element. Results also showed the superiority of Bougainvillea glabra over Ficus benjamina L., Ligustrum vulgare L. and Bauhinia variegate Linn. Bougainvillea glabra is classified in the study as an accumulator plant important to purify the environment from the cadmium element.

Research summary
تهدف هذه الدراسة إلى مقارنة قدرة أربعة أنواع نباتية مزروعة في حديقة الفرسان في مدينة اللاذقية على امتصاص ومراكمة عنصر الكادميوم (Cd) الناتج بشكل رئيسي عن وسائل النقل. الأنواع المدروسة هي Bougainvillea glabra، Ficus benjamina L.، Ligustrum vulgare L.، وBauhinia variegate Linn. جمعت عينات من الأوراق، القلف، الخشب والتربة، ثم تم تجهيزها للتحليل باستخدام جهاز التحليل الطيفي بالامتصاص الذري. أظهرت النتائج أن أعلى تركيز للكادميوم وجد في قلف الجهنمية (4.4 ppm)، يليه في أوراق الجهنمية (4.2 ppm)، ثم في قلف التين الباكي (3.93 ppm)، وأخيراً في قلف خف الجمل (3.55 ppm). بينما كان أقل تركيز له في خشب التين الباكي (1.66 ppm). تشير النتائج إلى أهمية الأنواع النباتية المدروسة في امتصاص ومراكمة الكادميوم، مع تفوق الجهنمية على باقي الأنواع المدروسة، مما يجعلها نباتاً مهماً لتطهير البيئة من الكادميوم وكدليل حيوي للتلوث به.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة في مجال معالجة التلوث البيئي باستخدام النباتات، إلا أن هناك بعض النقاط التي يمكن تحسينها. أولاً، كان من الأفضل توسيع نطاق الدراسة لتشمل أنواع نباتية أخرى قد تكون أكثر فعالية في امتصاص الكادميوم. ثانياً، لم تتناول الدراسة تأثير العوامل البيئية المختلفة مثل التربة والمناخ على قدرة النباتات على امتصاص الكادميوم. ثالثاً، كان من الممكن تقديم تحليل أكثر تفصيلاً حول الآثار الصحية والبيئية لتراكم الكادميوم في النباتات. أخيراً، لم تتطرق الدراسة إلى كيفية تطبيق النتائج على نطاق واسع في المناطق الحضرية الأخرى.

This study aimed to study the accumulative abilities Ricnius Communis & Phragmites Communis for lead and cadmium. This plants are native near the RMAILAH river in JABLAH city. The plants samples were collected from leafs, wood, and bark for plant sp ecies, the soil samples were taken at (0-20)cm depth. Concentration of heavy metals were determined in soils and plants with "Atomic Absorption Spectrophotometer" Our results showed that the amounts of pb in the soil samples were 61.89ppm. The concentrations of lead pb in the parts of Ricnius Communis range between 4.3 to 5.81ppm; in the parts of Phragmites Communis range between 1.46 to 2.32ppm. According to statistics analysis Ricnius leaves surpass Ricnius wood and bark with accumulate lead; and Ricnius surpass Phragmites with accumulate lead too. Our results showed that the amounts of cd in the soil samples were 3.081ppm. The concentrations of Cd in the parts of Ricnius Communis range between 0.031 to 0.061ppm; in the parts of Phragmites Communis range between 0.031-0.055ppm. According to statistics analysis there is no moral differences between Ricnius and Phragmites with accumulate cadmium.
This study aims to compare the ability of three plant species (Eucaleptus camaldulensis L., Acacia cyanophylla L. and Ricinus communis L.) on the accumulation of cadmium (Cd) resulting from the different existing pollution sources in the study area ( Abdul Qader Al Husseini Street - Latakia) especially resulting from traffic. The samples were collected from different parts (leaves, wood, bark) of the species mentioned in addition to samples of the soil, then the samples were processed and analyzed by atomic absorption spectrophotometer. The results showed a difference in the content of cadmium in the studied species, ranged between (0.25 mg/kg) and (0.42 mg/kg) dry weight, where the highest content in Ricinus wood (0.42 mg/kg) and then Eucalyptus wood (0.4 mg/kg) and minimum content in Acacia wood (0.32mg/kg). Ricinus and Acacia showed high ability to accumulate cadmium reaching Bioconcentration factor (BF=1.33) for Ricinus and (BF=1.13) for Acacia
this research aimed to study the ability of both reeds (Phragmites communis) and poplar trees (Populus nigra) to accumulate Cd and Zn. Where speared naturally prevail on the sides of the Rumaila River in Jableh town (research site), during 2014-201 5. Average amount of Cd on studied site was 3.081 ppm dry weight. Compared with the normal range of soil content from Cd (0.06-1.1 ppm), we found that it is three times the normal upper limit, indicating site contamination with Cd. The study showed that the Cd concentration in the reed shoots was 0.031 ppm, while it was up to 0.055 ppm in leaves than that of shoots. The value of bio-accumulation factor (BF) was 0.014. Also for poplar, the study revealed predominance of leaves over bark with Cd concentration of 0.034 ppm versus 0.016 ppm for poplar bark. BF value was 0.02. Regarding average amount of Zn in the soil of studied site was recorded 116.61 ppm of dry weight. Compared with average range of Zn in different types of soil (40-100 ppm), we find that it is slightly higher than the normal upper limit, showing site contamination with Zn. The study stated that the Zn concentration in reed leaves was 9.05 ppm versus 8.03 in the shoots. BF value was 0.07. Zn concentration in poplar leaves was the lowest at 5.13 ppm versus 6.07 ppm for the bark. We notice from these findings that the Zn amount in the parts of poplar plant is approximate. BF value was 0.05. The statistical analysis showed significant superiority of reed to poplar in terms of Cd accumulation, and the same for Zn.
تعد التربة والماء أهم المصادر الطبيعية غالية الثمن التي يستخدمها الإنسان في الزراعة و التمدن ولكن أصبحت عرضة للتلوث على نحو خطير بسبب الأنشطة البشرية حيث ربط الباحثون المشاكل البيئية بالتقدم الصناعي الهائل الذي بدأ في العام 1950 وكذلك بالأنشطة الزراعية والذي بدأ في النصف الأول من القرن العشرين
This study estimated the levels of lead and cadmium in 12 chocolate and cocoa samples from latakia markets by atomic absorption spectrometry . Most of the samples, were well known Syrian trademarks. The results showed that concentration of lead in samples of dark chocolate ranged between 0.061 and 0.49 mg\ kg ,and in samples of cocoa between 0,10 and 0,51 mg\ kg, but it was much less 0.01 - 0. 16 mg\ kg in white chocolate and Imported chocolates. concentration of cadmium in samples of dark chocolate ranged between 0.01 and 0.24 mg\ kg and in samples of cocoa between 0.03 and 0.231 mg\ kg. but it was also less in white chocolate and imported chocolates 0.01 - 0.051 mg\ kg. The results indicated that dark chocolates have higher concentrations of lead and cadmium than white chocolates and that the levels of lead and cadmium are generally higher than the common levels in developed countries ,and thus. might be a significant source of lead and cadmium ingestion, Raw materials should be checked before use for metal contents in order to decrease the concentrations of these metals in final chocolate products..
