هدف هذا البحث إلى دراسة مقدرة كل من القصب الشائع Phragmites communis و الحور الأسود الحموي Populus nigra v.hamoui على مراكمة عنصري الرصاص Pb و النحاس Cu المنتشرين بشكل طبيعي على جانبي نهر الرميلة في مدينة جبلة. جمعت العينات النباتية خلال عامي 2014-2015 , و ذلك في أربع مكررات لكل عينة.
This research aimed to study the ability of both reeds (Phragmites communis) and poplar trees (Populus nigra V.hamui) to accumulate Pb and Cu. Where speared naturally prevail on the sides of the Rumaila River in Jableh town (research site), during 2014-2015.

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 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 research was carried out during 2014 - 2015. The research aimd to describe
some chemical characteristics of the river's water used for irrigation, chemically compare it
with the Syrian Standards Specifications in terms of salt quantity and qua
lity and Cd and B
concentrations, water samples were taken from four observation points along the river:
A (domestic), B (industrial), C (mixed) and D (estuary), also Soil samples from the river
edges were also analyzed. The findings revealed that the EC value in B was 0.61 mg/l i.e.
less than those of others, with significant difference 0.72, 0.74, 0.73 mg/l, respectively.
The study also showed a significant increase in B and C concentration by 0.48 and 0.49
mg/l, respectively, compared with A and D by 0.4 mg/l each. A significant increase in Cd
concentration was noticed for B, C and D by 0.73, 0.88 and 0.75 mg/l vs. A 0.67 mg/l.
However, Cd concentration in the river water in all seasons and sites was excessive and
higher than the permissible limit for water discharge into seas estimated at 0.05 mg/l,
whereas the other parameters were lower than the permissible limits according to the
Syrian Standards. The effect of water pollution on soil showed a significant increase in EC
for B by 1.01 dS/m than others. The increase was also more significant in subsurface layer
than surface one by 0.45 and 0.62 dS/m, respectively. In addition, the findings
demonstrated a significant increase in Cd for C (2.67 mg/kg) than other points. The
increase in Cd concentration was more significant in the surface layer (2.648 mg/kg) than
the subsurface one (2.631 mg/kg), and this concentration was lower than the normal range
of soil content from Cd (3 ppm).
The aim of the study was to study the ability of the leaves of the figs (Ficus
retusa L.) and (Phoenix dactylifera L.) in the city of Tartous to accumulate the
lead elements (Pb), nickel (Ni).
