Concentrations of elements in floral and acacia honey from Bosnia and Herzegovina and the Republic of Croatia

Abstract

Cilj ovog rada bio je istražiti postojanje razlika u mineralnom sastavu dvije vrste meda iz Bosne i Hercegovine (BH) i Republike Hrvatske (HR) obzirom na botaničke razlike i zemljopisni položaj. Ispitane su dvije vrste meda: bagrem (Robinia pseudoacacia L.) i cvjetni med, s područja BH i HR. Koncentracije makrolemenata (Ca, Mg, Na), mikroelemenata (Ag, Co, Cr, Cu, Fe, Mn, Mo, Se, Zn) i toksičnih metala (Al, As, Ba, Cd i Pb) određene su primjenom induktivno spregnute plazme s masenom detekcijom (ICP-MS). Koncentracije elemenata su određene u rasponu (mg kg-1, BH/HR): Al 0,18-6,25/0,31-7,28; Ca 19,9-61,2/5,97-137; Na 4,82-50,3/2,16-47,0; Mg 9,75-55,9/2,09-68,5; Fe 0,38-1,89/0,22-3,04; Mn 0,21-3,54/0,06-7,16; Cu 0,05-0,47/0,05-1,01; Zn 0,32-1,72/0,15-11,7; (μg kg-1): Ba 20,7-167/8,6-251; Cd 11,2; Pb 10,3/10,3- 72,1; Co 9,71-49,7 /13,7-94,8; Mo 11,9-33,3. Krom je određen u samo tri uzorka cvjetnog meda porijeklom iz HR u rasponu koncentracija 15,0-143 μg kg-1. Od ispitivanih toksičnih metala (As, Cd i Pb) najviša koncentracija Pb zabilježena je u uzorku cvjetnog meda (72,1 μg kg-1). Najviše koncentracije određene su za makrolement Ca, a od mikroelemenata za Mn. Obzirom na geografsko podrijetlo iz BH i HR u bagremovom medu utvrđene su statistički značajne razlike u koncentracijama elemenata Al, Na, Mg i Mn, odnosno za bagremov i cvjetni med za Ba i Ca. Nisu ustvrđene značajne razlike u koncentracijama elemenata As, Pb, Cd, Fe, Cu i Zn obzirom na geografski položaj, odnosno podrijetlo iz BH ili HR.The aim of this study was to investigate the differences in the mineral composition of two honey types from Bosnia and Herzegovina (BH) and the Republic of Croatia (HR) with respect to botanical differences and geographic position. Two types of honey, acacia (Robinia pseudoacacia L.) and flower honey were observed from BH and HR areas. Macroelement, (Ca, Mg, Na), microelements (Ag, Co, Cr, Cu, Fe, Mn, Mo, Se, Zn) and toxic metals (Al, As, Ba, Cd and Pb) concentrations were determined using inductively coupled plasma with mass detection (ICP-MS). The concentrations of the elements are determined in the ranges (mg kg-1, BH/HR): Al 0.18- 6.25/0.31-7.28; Ca 19.9-61.2/5.97-137; Na 4.82-50.3/2.16-47.0; Mg 9.75-55.9/2.09-68.5; Fe 0.38-1.89/0.22-3.04; Mn 0.21-3.54/0.06-7.16; Cu 0.05-0.47/0.05-1.01; Zn 0.32-1.72/0.15- 11.7; (μg kg-1): Ba 20.7-167/8.6-251; Cd 11.2; Pb 10.3/10.3-72.1; Co 9.71-49.7 /13.7-94.8; Mo 11.9-33.3. Chromium was determined in only three samples of honey from HR in the range of 15.0-143 μg kg-1. the highest concentration of the toxic metals (As, Cd and Pb) tested was measured for Pb in a floral honey sample (72.1 μg kg-1). The highest concentrations were determined for macrolement Ca, and of microelements for Mn. Considering the geographic origin of BH and HR in acacia honey, statistically significant differences were found in the concentrations of Al, Na, Mg and Mn, respectively, for acacia and flower honey for Ba and Ca. No significant differences were found in the concentrations of the elements As, Pb, Cd, Fe, Cu and Zn in terms of geographic position or origin of BH or HR
