Sažetak
Beeswax is natural product of honeybees. it is an extremly complex mixture consisted mainly of esters of higher fatty acids, alcohols, hydrocarbons, acids and other minor substances, like proteins. Lead is one of principle toxic heavy metal and contained at environment can contaminate honeybee Products, primary nectar and honeydew, but as consequence of order and way performing social activity of foragers and house bees, also combs and inside hives. There is a very few studies on lead contamination of beeswax and lack of dana about its influence of comb foundation quality and correlations with rearing and biological characteristic of brood of honeybee colonies situated on contaminated combs. also, thw effectiveness of performing casting comb foundations production tehnology with long term of cooling on reducing heavy metals is total unknown. To compare the concentrations of lead in different layers of wax a 15 samples were collected. beeswax samples were digested using microwave closed system. concentrations of lead were mesured by graphite furnace-atomic absorption spectrometer Analyst 800. concentrations of lead were in range: 28, 118-71, 971 after resolving was combs, 17, 336-66, 251 after sterillisation upon 125 0C, and 1338, 277-10801, 479 after sedimentation, respectively. The obtained results indicate a tendency to reduce the lead content in the wax and comb foundations as final product contain lowest concentrations and material was used just from highest layer.
