This study aimed to determine of Coliform group in each of the
soil , groundwater and plants in the villages of Taldo and Tal El-
Zahab –Homs. The necessary tests has been conducting for the
detecation of Coliform group for indicate to pollution b
y sewage .
The results showed great pollution in the samples of soil which
irrigated by sewage . A positive correlation was identified between
B.O.D.5 and enumerate Coliform group in water samples studied,
and plant samples were contaminated with Coliform group, and
the control samples were uncontaminated with Coliform group.
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
Alsin Spring is the most important water sources in Syrian coastal area, due to it is the source of drinking water for the main cities and towns in the Syrian coast. This research aimed to study some contaminant indicators in Alsin spring and some t
aps of distribution system of Alsin drinking water, and compare the Indicators with samples of bottled drinking water from Alsin spring and three other water sources (Drekish, Bukkeen, and Alfigeh). The study included determining the concentrations of nitrates, nitrites and some heavy metals including lead, cadmium and nickel in water samples. The results showed that all water sources contain varying concentrations of lead, while the nickel and cadmium were vary in drinking water samples; The concentrations of nickel and cadmium in some samples were low while were under the detection limits in other samples. The analysis of samples of bottled drinking water showed that the samples from Alfigeh spring were the lesser contamination with heavy metals, while the samples from Alsin spring were contain highest concentrations of lead and nickel. The samples of bottled water from Bukkeen spring contain the highest level of cadmium. The results showed that the concentrations of nitrate, nitrite and heavy metals differ depending on the water source. However, all these concentrations were lower and within the acceptable limits of Syrian standard for drinking water. The study concluded that water resources in the coastal area are distinguished with their higher pure.
The aim of the present study was to determine the levels of lead and cadmium in the
meat, liver and kidney of sheep exposed in the local markets of the city of Latakia, and to
compare the results with those reported by other countries and with the
maximum
acceptable levels for human consumption, Lead and cadmium were determined by atomic
absorption spectrometry (AAS).
The mean concentrations of lead in meat, liver and kidney were 0.043, 0.284 and
0.118 mg/kg fresh weights, respectively, while mean concentrations of cadmium were
0.017, 0.173 and 0.252 mg/kg fresh weights, respectively. Statistical analysis showed a
significant difference in lead and cadmium concentrations between liver and kidney and in
meat.
Concentrations of eight chlorinated pesticides: namely, gamma HCH, Heptachlor,
heptachlore epoxide, aldrin, dieldrin, 4,4-DDE, 4,4-DDD, and 4,4-DDT were studied in
some mollusks species Monodonta turbinata, Brachidontes variabilis , Patella caerule
a,
Trochus erithraeus, Strombus persicus and in sediments taken from five different
locations: Assin estuary, Jobar estuary, Banias Thermal Electricity Station, Albasia, and
Mirkiya River estuary. Sampling was performed at six different times during the period
2006-2007.
Results indicated that Assin estuary contained the highest level of contamination
followed by Jobar estuary and Mirkiya estuary where sampled mollusks species contained
various concentrations of all of the studied pesticides. At Banias Thermal Electricity
Station samples showed contamination with heptachlore and heptachlore epoxide only,
whereas the concentration of pesticides at Albasia location, much lower than the other
locations.
Food safety and monitor of the contents of agricultural products are matters of great
importance for consumers, as a result of food awareness, public health and disease
prevention.
The aim of this study is to know the concentrations of some heavy
metals (lead -
cadmium - nickel - chromium), in some fodder plants (Trifolium ssp., Cynodon dactylon.,
Avena sativa L.), and the extent of its secreted in the milk of cows in the area of Banias on
the Syrian coast.
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
spectrosco
py (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.
One hundred samples of Bacteriological swabs were obtained of medical
team clothes, treatment and surgery tools, and patient covers and napkins,
from treatment and surgery rooms in the hospital of maxillo-facial surgery
at the Faculty of Dentistry
- Damascus university, before utilization for
checking the sterilization, and after utilization for detecting staphylococci
and determining its species that spread in the course of different dental
treatments and surgical procedures.
In this study, sterility for all studied samples was shown before utilization,
but after utilization we observed complete contamination in glove samples
with percentage (100%), while the samples of masks and tools and napkins
showed (50%) of contamination, and the samples of medical team clothes
and patient covers kept most of them (80%) of their sterility after
utilization.
This research aims to evaluate the water quality of the Al-Sain lake which feeds
mainly the Lattakia city and a part of the Tartous city of drinking water purpose.
In this paper, we study a group of physical and chemical factors for the water of th
e
Al-Sain lake during the years of available data (1991-2004-2007-2011), samples were
taken from four different locations according to the program approved by the concerned
staff to monitor and protect the lake, namely: (Lattakia water supply point, Tartous water
supply point, irrigation point, southern spring observatory), and we calculated the quality
index for drinking purposes using US approved methodology of National Sanitation
Foundation. Nine factors have been adopted: (dissolved oxygen, fecal coliforms, pH,
BOD5, temperature, phosphate, nitrates, turbidity, and total solids).
The research result showed that the classification of water quality was good in all
four monitoring points during the years 1991 and 2004, noting a significant improvement
of the quality in 2004, and decreases slightly during the years 2007 and 2011 for
monitoring points in the Lattakia water supply and irrigation points, but water quality still
keep maintain a good classification, while the quality of the water goes down within the
threshold of middle classification for the Tartous and southern spring observatory
monitoring point.
To clarify the possibility of using bacterial flora as a pollution indicator,
water samples from river were collected and analyzed from July ١٩٩٩ to
February ٢٠٠١ for dissolved oxygen (DO), NO٣-N, NO٢-N, NH٤-N, PO٤-P,
suspended solids (SS), biolog
ical oxygen demand (BOD) Heterotrophic Bacteria
were identified to genus level, and another part of it was identified to
Enterobacteriaceae.
