Metal Content in Honey with Different Coloring from Industrial Areas of Bosnia and Herzegovina

Honey is the food which is used by humans since ancient times and is highly valued due to its nutritional value. Most metals which are found in soil - plants system can be found in honey also. The aim of this research is to see could some metals from industrial areas of Bosnia and Herzegovina be found in honey samples and to see is there a difference in amount of metals in dark and light versions of honey. In honey samples some basic quality parameters were measured: water activity, pH, electrical conductivity, moisture content, dry matter content. Also, concentrations of five metals were determined: K, Na, Ca, Mg and Fe. Concentration of metals were determined by means of FAAS (Flame Atomic Absorption Spectrophotometry) and FP (flame photometry). For statistical evaluation, descriptive statistics was used, one – way ANOVA, and correlation. The results are showing differences between honeys from different industrial areas, and among honeys of different coloring. High correlations (above 0.900) were found between concentrations of K and pH (0.962) and between K and EC (0.975).
