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.
We present in this study accumulate of two heavy metals (Fe - Cu) in the tissues of
flowers , leaves , stems and roots of Lamium moschatum Mill.
The study showed that the plant accumulated (Fe - Cu) in different concentrations ,
with an increase i
n the concentration of (Fe) in all samples specially in roots . The highest
concentration of (Cu) was in flowers (1669.23 mlg/kg) , and for (Fe) was in roots (4539.5
mlg/kg) .
The results showed a convergency in the concentrations of (Cu) in the parts of plant
for the same sample (432.62 - 490.75 - 353.409 - 272.73 mlg/kg) in flowers , leaves , stems
and roots in order . but the concentrations of (Fe) in roots was higher than that in flowers ,
leaves and stems for the same sample .
In sample -5- the value of (Fe) in roots was (1124.91 mlg/kg) but in flowers , leaves
and stems at the same sample was ( 234.83 - 218.82 - 205.24 mlg/kg ) in order.
The concentrations of copper (Cu) and zinc (Zn) in samples of some cereals available at
local markets in Syria weredetermined, after nitric digestion, using Atomic Absorption
Spectrometry. The study showed that the heavy metals were present in all
samples at different
levels. The concentration of heavy metals varied from trace to higher concentration.
The maximum level of copper (Cu) in the cereal samples was 0.426 mg kg-1 on dry
weight basis, where the maximum level of zinc (Zn) in the cereal samples was 2.325mg mg kg-
1 on dry weight basis. The analytical results obtained for the heavy metals indicate that the
copper and zinc were present in all samples at concentration well below the acceptable
concentration recommended by the World Health Organization.
The concentrations of Copper (Cu) and Zinc (Zn) in samples of some spices
available at some local markets in Syria were determined, after nitric digestion, using
Atomic Absorption Spectrometry. The study showed differences in metal concentrations
according to the edible part. Studied heavy metals were present in all samples at different
levels. The concentration of Copper (Cu) and Zinc varied from trace to higher
concentration. The maximum level of Copper (Cu) in the spices samples was 0.668 mg/kg.
The maximum level of Zinc (Zn) in the spices samples was 2.523mg/kg. The analytical
results obtained for the heavy metals indicate that the Copper and Zinc were present in all
samples at concentration well below the acceptable daily intake recommended by the
World Health Organization.

Studied the distribution coefficient of elemental copper and lead contaminants in the aqueous phase using a Bi-phase system: solid phase (the sands of Palmyra) and liquid phase (water containing the former two elements), where they were sampling sand
samples from different regions in Palmyra to investigate for possible use as an adsorbent for elemental copper the lead from contaminated water, and after adjustment for certain transactions from time mixing phases, granular size, concentration of hydrogen ions, the concentration of the contaminated ingredient, the concentration of rival element (calcium) in addition to the ratio v / m in order to get the best rate for removal of these elements. The removal rate of copper componentamounted to 99.9% using four sites samples of sand a Palmyra, (al qareaten - the third leg to pump crude oil T3 - Alhl field - the valley between Mount aldahek and Sokhna) For lead removal ratio stood at 76.35% for the qareaten and 87.75% of the station the third to pump crude oil and 95 0.0% of the field Alhl and 96.25% of the valley between Mount aldahek and Sukhna. The application of the conditions that we have obtained in the laboratory to industrial water samples from the water income for the unity of treatment in Banias refinery and Water Company Drinaj of the Syrian Company for Oil Transport and the ratio of the removal of lead in the four samples ranging from ( 97.79 - 100)% for water Banias Refinery Company ranged between (83.89 - 88.08)% for water Syrian Company for Oil Transport, while the percentage of removal of the copper in the four samples ranging from (96.52 - 99.37)% for water Banias refinery Company and ranged ratio remove copper from the Syrian Company for Oil Transport water between (82.66 - 96.28)% in four samples.
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.
The samples of bee pollen were collected from inside and outside
the honey beehives of apiaries situated in five different locations of
Latakia; Al-Qardahah, Al-Haffeh, Jableh, Latakia city and Eastern
Entryway to Latakia during the autumn in 2014
. The
concentrations of three heavy metals, zinc (Zn), lead (Pb), cadmium
(Cd) were determined in pollen by using atomic absorption.
The aim of the study is to determine the concentration of some heavy metals in some
imported tattoo inks (black and colored).
Sold in Homs, Tartous, Ybroud and DeirAtieh, and assess whether tattoo inks comply with
maximum concentrations of heavy m
etals in the EPA’s guid line -2012 and find out the
relation of colours by Ni, Cu, Pb, Cd and Cr contents.
18 Samples of tattoo inks purchased from different sources.
5 Samples black, 4 samples green, 5 samples red, 2 samples brown,1 sample white and 1
sample oily.
This samples reveals that the concentration of heavy metals previously mentioned very
high and varies depending on the source of the tattoo ink.
These concentrations above the maximum limits according to the EPA’s-2012 quid line.
This study reveals also that the type of pigment used in tattoo inks contributes to its heavy
metal content.
The use of tattoo inks could result increase in the heavy metal level in human body which
could lead to health problems.
أصبح تأثير الانسان على البيئة واسع النطاق وقد أدى إلى تغيرات بيئية كثيرة بعضها غير عكوسة ففي حين تكون التغيرات الجيولوجية والبيولوجية لسطح الأرض بطيئة عادة إلا أن الانسان قد تسبب في تغيرات سريعة في العقود الأخيرة
