تم قياس تراكيز كل من النحاس و الزنك و النيكل و الرصاص و الكادميوم في نحل العسل الحي و الميت باستخدام جهاز الامتصاص الذري. جمعت العينات من مناحل ثابتة في خمس مواقع مختلفة بمحافظة اللاذقية: القرداحة (اسطامو)، الحفة (دبا)، جبلة (الصنوبر)، مدينة اللاذقية (الرمل الشمالي/ أتوستراد الجمهورية) و المدخل الشرقي لمدينة اللاذقية (خلف معمل الجود) خلال فصلي الربيع و الخريف من عام 2014 .
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.

The aim of this study isto determinat the concentration of (Pb, Cu, Cd, Co, Cr , NiZn,
Fe) in storm water and their content of sediments during four seasons, the samples were
collected in four areas along Tartous beach. After make necessary treatme
nt concentrations
of elements determination by flame atomic absorption spectrometry.The results showed a
high levels of elements iron and zinc, in stormwater (138.6 μg/l - 99.7 μg/l) and sediments
(17.863 μg/l – 138.735 ppm), in all samples and there were concentrations another
elements difference between stations and rainfalls related to the human activities.
The purpose of this research is to deduce the basis for calculating the cost of honey bee
products since the actual costing of various levels on accurate basis is the right starting
point for achieving all the goals of the cost systems. Because the
actual cost is the basis of
planning, control and reduction of that cost. Lack of information to properly determine
product cost may cause choosing unhealthy competitive strategies, and make bad
decisions, whether it related to product pricing or product selection.
The research objective was reached through an analytical study of previous studies that
discussed the economic feasibility of honey bee production projects in a variety of
environments. In addition, a field study was carried out on the working beekeeping firms in
Lattakia governorate during the period between the month of 11/2017 and the end of the
month 8/2018.
A number of conclusions were reached on the determinants of the cost of honey bee
products, including the need to rely on the variable cost approach in preparing the list of
honey product costs, the adoption of the production season as a period for the preparation
of this list and a number of conclusions regarding the basis for calculating the depreciation
of the assets of the honeybees and classified it as fixed cost which must included in the
income statement for the financial cycle which ends at the end of the production seasons
on 31/10 of each year.
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.
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.
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.
