This study was conducted to identify the levels of heavy metals (lead, cadmium, mercury, nickel, copper, iron, zinc) in the following processed local and imported meat: Sardine (canned full), Tuna (canned chunks), Hammour (frozen full), Euphrates Fis
h (frozen full), fish produced at Qattinah Lake in Syria (frozen full) , lamb (frozen ground), beef (frozen ground), lamb sausage (frozen full), beef sausage (frozen full), sausageproduced in Netherlands (frozen stuffed), lamb liver (frozen full), broiler chicken liver (frozen full), broiler chicken (frozen full), chicken mortadella (canned), beef mortadella (canned), chicken mortadella (canned) produced in Netherlands. Heavy metal concentrations were identified in the samples of the studied meat by atomic absorption spectrometer. The concentrations taken in the wet weight measured in (ppm) were as follows: lead values range between (0.1–5.61),cadmium(0.01–2.02), mercury (0.14 –79.01), nickel (0.11 - 0.82), copper (0.24 – 6.89), iron (1.01 - 91.03), zinc (8.14 - 45.5). It was noticed that in some of the studied samples of the imported and locally-processed meat the levels of lead, cadmium, mercury, and nickel were above the levels permitted by WHO (World Health Organization) and by FAO (Food and Agriculture Organization).While the concentrations of copper, iron, and zincwere belowthelevels permitted.
This research carried out in Al- Bassa village at Lattakia province during 2013-2014, to determine the effects of increasing rates of boron and zinc fertilization by foliar spraying, on root nodulation and seed yield of broad beans (Viciafaba L.). Se
eds were planted in plastic pots (15 kg capacity), filled with sandy-silty soil, characterized by its poor content of boron, and represents most of lands in the region. Boron and zinc were sprayed by five increasing concentrations (Bo, B25, B50, B75 and B100) and (Zno, Zn25, Zn50, Zn75, Zn10)on broad bean plants at 33 and 65 days post-emergent. Results showed that treatments high significance than control, in termsof root length witch the best treatment was B100Zn100with 31c.m, and 2.85 g for B75Zn75 as a wight of length, on the other hand the best treatment for number of nodules was B75Zn75, 179.03 c.m, B100Zn100 was the best for height of the plant with 100.20, for protein B100Zn100 the best with 37.4%, However, boron and zinc fertilization treatment B75Zn75 is the best, economically.
The sludge of wastewater used in agriculture processes, in order to knew the effect of
its application on soil and plant contents from zinc and cadmium, Hordeum vulgare L. was
planted by using graded amounts of sludge to the soil for two years, fou
r treatments were
used: o kg/pot (control), 2, 4, 6 ton/ha (with 5 erplicates for each treatment), concentrations
of zinc and cadmium in soil, roots, straw, and grain in all treatments were measured.
Results showed that the application of sludge improve the physical and chemical
properties of the soil, the concentration of zinc and cadmium in the soil were 164.66 μg/g,
324.22 ng/g, respectively, in 60 ton/ha treatment.
Concentration of Zn increased significantly and showed positive correlation with the
amount of sludge, the highest concentration of Zn was in root of plant in comparison with
other parts of plant, in all treatments, it was 69.3 μg/g in the root while it was 45.15, 38.2
μg/g in straw and grain respectively, in 0.6 kg/pot treatment.
Concentration of cadmium increased significantly in 0.6 kg/pot treatment in
comparison with control, the highest concentration was in the root of plant in comparison
with other parts of plant.
This study showed that Hordeum vulgare L. doesn't accumulate zinc and cadmium
because it´s concentration in roots was higher than in straw and grain.
Concentration of Zn and Cd still within permissible limits in the soil and plants in all
treatments.
Field experiment was conducted during the season (2011 – 2012) at Bhanine village
in Tartous city. Maize seeds of Ghouta 82 variety were planted in plastic pots filled with
calcareous soil .Treatments including three levels of B (0, 3, and 6 kg.ha−
1) and four levels
of Zn (0, 8, 16 and 24 kg.ha−1) added to the soil, in a completely randomized block design
with three replications, to study the effect of different levels of boron and zinc and their
interactions on maize content of some nutrients. Results of this study showed that there
was a clear effect of B and Zn and their interactions in soil on leaf content of Mn, Fe and
Cu. High amounts of zinc in the soil had a clear effect on reduced leaves content of B and
increased its content of K. The presence of a of B in the soil, assisted to increasing of leaf
N content. There was a significant effect of B and Zn interaction on leaf content of Zn, and
no effect on leaf P content.
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 concentrations of copper (Cu), zinc (Zn), nickel (Ni), lead (Pb),
cadmium (Cd) in dead and live honeybees were determined by using
atomic absorption spectrophotometry. The samples were collected from
beehives of stationary apiariessituated in
five different locations of
Latakia; Qardahah (Asitamo), Haffeh (Dabba), Jableh (Snouper),Latakia
city (Al-Ramel Al-Shamali\ Autostrade of Al-Jomhouria) and Eastern
Entryway to Latakia (behind Al-Jood factory) , during the spring and
autumn in 2014.

zinc) in the following spices: Nutmeg, turmeric, cinnamon, ginger,
cardamom, nigella sativa, black pepper, cumin, coriander, curry,
and mixed spices.
The study was carried out in apple orchard and at the laboratories of Agricultural
Scientific Research Center, and Pome and Grapevine Division in Sweida (GCSAR),
Syria, during the growing seasons of 2015 and 2016 to study the effect of organic

idues, and boron and zinc addition on some soil characters, fruit set ratio and
some fruits qualitative traits in Starking delicious apple cultivar in Sweida.
