Abstract
In the present work, the results of analysis of 10 Libyan honey samples, representing various floral honeys, collected from Benghazicity during different seasons in 2009-2010 were demonstrated. All samples were examined for the physicochemical quality parameters, phenolic compounds and heavy metals contents. The moisture; optical density (O. D.); electrical conductivity; water insoluble solids; ash content; pH; total acidity; hydroxylmethyl furfural (HMF); sugar contents and phenolic compounds content were detected according to AOAC 1990-Official Methods and reference methods. The results were compared with Libyan Standard Legislation and the European Standard Legislation. The obtained results indicated that the quality of the tested Libyan honey samples were very good and worth to the world standard properties of honey. Even more, the tested Libyan honey samples have high level of phenolic compounds content. On the basis of heavy metals content, three metals were determined (Cadmium, copper and lead) using atomic absorption spectrophotometer. The level of each metal-content was variable, which may be due to the conditions of processing, packing and storage conditions of Libyan honey samples.

Honey is defined as “the natural sweet substance produced by honey bees from nectar of blossoms or from secretions of living part of plants, which collected by honey bees”

The researchers in this study found that the concentrations of the metals such as cadmium, copper and lead were varied in the different honey samples, due to differences in honey types, the geographical regions and the weather of each region
Summary
Honey is defined as “the natural sweet substance produced by honey bees from nectar of blossoms or from secretions of living part of plants, which collected by honey bees”. They transform and combine their secretions with specific substances of their own, store and leave in honey comb to ripen and mature” [1,2,3]. Honey is produced in almost every country of the word and it has been consumed as a high nutritive and very important energy food. Honey cannot be considered as a completed food for human nutritional, but it offers potential as a dietary supplement [5]. This study detected some of physicochemical properties, such as moisture; electrical conductivity; color; sugar content; total pro-
