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.
This study was conducted in the Syrian coastal region, and the honey samples have
been collected from eight different sites belonging to the provinces of Latakia and Tartous
during the autumn of 2012. Their content of heavy metals (zinc, copper, le
ad & cadmium)
was estimated by Atomic Absorption at the Higher Institute for Environmental Research at
Tishreen University. The results showed that zinc concentration in the bee honey samples
ranged from 2.86 to 12.64 mg / kg (mean 7.98±3.67), and copper ranged from 0.125 to
0.652 mg / kg (mean 0.328±0.176 ), lead ranged from 0.084 to 0.378 mg / kg (mean
0.205±0.112), cadmium ranged from 0.0002 to 0.0132 mg / kg (mean 0.0053±0.0052). The
results indicated that the largest amounts of heavy metals were found in honey sample
taken from the apiary which is located at the eastern entrance of Latakia city (near Joud
factory), while the lower concentrations of zinc and lead were in Banias area (Wadi Al
Saqi), and the least concentration of copper was in Safita area, and of cadmium was in the
Gablah area (Bani Qahtan Castle).Comparing elements concentration in the studied honey
samples, Zinc concentration was found to be the highest, followed by copper, lead and then
finally cadmium.The results of statistical analysis indicated the existence of significant
differences between the studied sites during the autumn of 2012.
This research was conducted in the countryside of Tartous, to aim for the analysis of moisture, protein, TSS and pH of royal jelly (RJ) harvested after 24 to 48 hours of grafting, compared with that traditionally harvested after 72 hours of grafting.
As well as to analysis of these compounds in (RJ) within cells to brood of workers, compared with the (RJ) product in cups. 50 samples were analyzed in wet weight and dry weight for (RJ), which was harvested in this research.
This study was conducted in the spring of 1999 in Al-Souida Region of
Syria, to know the effect of flower pollination by honeybees on flower and fruitset
and on the crop productivity of three varieties of apple. The experiment was
repeated in the
spring of 2001 on the same varieties in addition to others like
Yellow sport, but the weather conditions (spring-frost) didn’t allow to obtain
results.
