2011
Hussein, M.H. | Rateb, S.H. | Salman, A. | Abou-Zeid, A.
Content of copper (Cu), lead (Pb) and zinc (Zn), was determined (mg/100 gm honey and p.p.m.) in 33 bee honey samples from north, middle and south of Egypt. These samples were compared with respect to botanical and geographical origin and time of collection from 2004 to 2010 years. More (Cu) and (Pb) were found in honey samples from north of Egypt, while more (Zn), and least content of (Cu and Pb) were detected in middle of Egypt. Least content of (Zn) and medium content of (Cu and Pb) were detected in samples from south of Egypt and Rea Sea. Higher content (p.p.m.) of tested heavy metals were found in north and middle of Egypt, while minimum content was found in south. Significant differences in heavy metals content (in p.p.m.) were detected between middle Egypt from one sie and each of north and south of Egypt from the another side. In general, more (Zn) was detected in samples, followed by (Cu), and (Pb). In citrus honey maximum content (mg/100 gm honey) of (Pb) and minimum content of (Zn) were observed. In eucalyptus honey, maximum content of (Cu) was detected, while maximum content of (Zn) was found in sesame honey. Minimum content of (Cu and Pb) were determined in medicinal and aromatic plants honey. Minimum content (mg/100 gm) of (Cu), or 0.119 mg and (Pb), or 0.009 mg were detected in honey collected during 2004, while maximum content, or 0.338 mg and 0.0256 mg, respectively were found in 2010 honeys. Higher content of (Zn) was noticed in 2005 honeys, then decreased, and afterwards increased from 2008 to 2010, however no significant differences were noticed between years or honey types, with respect to heavy metals content. Relation between heavy metals content in Egyptian honey and environmental pollution was discussed, and is of special merits.
