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.
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.
The importance of research being deals with the problem of
significant environmental concern the pollution of the plant , soil
and air component lead as a result of rapid industrial development
since the twentieth century . Was selected Eucalyptus
for several
considerations , including the widening spread and being one of
the bumpers wind that might ease the arrival of pollutants in the
atmosphere to regions far geographically . was selected several
sites of Homs in order to examine the content of the soil and
leaves Eucalyptus from a bullet was found that the concentration
of lead element in the plant was caused by air pollution , where not
shown the existence of relations clear engagement between the
content of soils of lead ( for a total and disposable absorption )
with the lead content of the plant . Ranged concentration of lead
overall in the soil between 1.98 ppm ( through Homs - peaceful )
and 72.47 ppm ( Highway Tartus in the south ) , and the average
of 4.857 ppm, did not exceed the concentration of lead in the
samples studied , both inside the city or outside the normal limit
and values lead stainless absorption in the soil ranged from ppm
(19.02- 0.02), ranged lead concentration in the plant between
2.01ppm and 10.35ppm and this concentration of lead element
within the permissible limits but with time become toxic showing a
lack of liaison relationships between the component lead either in
the soil or plant with the CaCO3 and Active lime. Finally we can
say that the contamination of the plant within the city is higher than elsewhere because of the busy traffic . Add to that the increase in soil lead content available led to increase the concentration of lead in Eucalyptus,leaves
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.
The research was conducted to study the resistance of Nerium plant which are planting on
sides of roads and the cities portals. The research was performed by studying the leaves of
Nerium plant, through studying the length and weigh of the leaf, an
d its area and water
content. In addition to studying the wools and hiatus and chlorophyll concentration, and
compared the results between the polluted region which is the entry of Banias City, and the
control one which is the gardens of Tishreen University.
Results showed non significant reduction in length, weight and area of the leaf in the
polluted region compared with the control one. It attained (16.2 cm, 0.97 g and 26.3 cm2),
respectively in the polluted region. Where it was (17.8 cm, 1.25 g and 27.7 cm2), for
control region, respectively. Also, there was no significant differences in water content
between the two studied regions. It attained respectively (52.2 and 53.9 %).
Our results showed:
- That a number of hiatus decreased, whereas the wools increased in the polluted region
compared with control region insignificantly. The mean of a number of it was 12 in
polluted region, compared with 14 in the control region.
- A simple insignificant reduction in the concentration of chlorophyll A in polluted region
compared with the control, where it attained (0.93 and 0.98), respectively.
The Nerium oleander plant was resistance and tolerance to the air pollution.
