Determination of trace elements in Croatian floral honey originating from different regions

The concentrations of As, Cd, Cu, Hg and Pb were determined in 54 multi-floral honey samples collected from five regions of Croatia during 2009 and 2010. Element contents decreased in the following order: Cu > Pb > As > Hg > Cd. Significant differences in lead and copper levels were observed between regions. Mean levels of elements (g kg-1) in all honey samples measured were: 19.7 for As, 1.51 for Cd, 1074 for Cu, 2.72 for Hg and 65.2 for Pb. Copper and lead were the most abundant elements in the Centre region with range and mean contents of 108 to 41271 and 3232 g kg-1 and 22 to 440 and 131 g kg-1, respectively. The highest element contents were: As 23.8 g kg-1 in the South region, Cd 2.11 g kg-1 in the Southwest region and Hg 2.63 g kg-1 in the Northeast region. The finding that lead contents in Croatian honey were higher than most reported lead levels in honey from other European countries is of particular concern. These indicate that the attention must be focused on setting positions for honey production hives in areas distant from highways and railways.
