“…The highest content of manganese (9.40 mg kg -1 ) was characteristic for buckwheat honey, being significantly lower in acacia (0.27 mg kg -1 ) and oilseed rape honeys (0.45 mg kg -1 ). Similarly to our experiment in the Lower Silesia, BOGDANOV et al (2007) found a higher content of manganese in linden than in acacia and oilseed rape honeys, whereas KOT and ZARÊBA (2008) reported the highest manganese content in acacia and buckwheat honeys.…”

“…Significantly more iron was determined in linden and goldenrod honeys (2.11 and 2.00 mg kg -1 , respectively) than in the other varieties. KOT and ZARÊBA (2008) found the highest Fe content in linden honey and the lowestin acacia one. The Swiss experiment (BOGDANOV et al 2007) demonstrated that acacia honey was the poorest in iron.…”

“…In unpolluted areas of Romania, the zinc content was the highest in linden honey and the smallest in oilseed rape honey (BRATU, GEORGESCU 2005), analogously to our tests completed in Lower Silesia. In honey samples collected in various regions of Poland, the Zn content was the largest in oilseed rape and linden honeys (KOT, ZARÊBA 2008). The zinc content in linden, buckwheat and oilseed rape honeys collected in Pomerania was on average: 4.33, 6.66 and 4.17 mg kg -1 , respectively (PRZYBY£OWSKI, WILCZYÑSKA 2001).…”

“…Less copper in honeys was found by BOGDANOV et al (2007): 0.180 mg kg -1 in acacia, 0.382 mg kg -1 in linden and 0.265 mg kg -1 in oilseed rape honey. The experiment conducted in Poland by KOT and ZARÊBA (2008) showed that buckwheat honey accumulated the largest amounts of copper (0.30 mg kg -1 ), with linden, oilseed rape and acacia honeys to follow. A high content of copper in buckwheat honey may be due to buckwheat's ability to absorb from the soil some hardly available elements, including copper, which in soil occurs in its hardly mobile forms.…”

“…The research is stimulated by the importance of honey in human diet. Honey is a source of many vital elements (KOT, ZARÊBA 2008). However, when present in excessive amounts, some of these elements may become a health hazard.…”

Analyzing the content of bioelements and toxic metals in honeys of various botanical origin is important for the consumers' health. In addition, many authors notice that results of such analyses can help to identify the botanical and geographical origin of honey and to use the product as a bioindicator of the overall contamination of the environment. The content of As, Cd, Pb, Zn, Cu, Mn, Ni, Mg, Fe, Cr was determined in samples of nectar honey (acacia, linden, goldenrod, multifloral, buckwheat, oilseed rape) originating from some areas in the Province of Lower Silesia unexposed to industrial and traffic emissions. In order to demonstrate differences in concentrations of the metals in particular honey samples, one-factor analysis of variance or the Kruskal-Wallis test was applied, and the correlation between levels of individual metals in the honeys was investigated. Similarities between the honeys with regard to the metal content were determined using Ward's method of cluster analysis. Among the analyzed nectar honeys from Lower Silesia, the content of zinc was the highest in linden flower honey (13.41 mg kg-1), copper and manganese-in buckwheat (1.50 mg kg-1 and 9.40 mg kg-1 , respectively), nickel-in multifloral (1.03 mg kg-1) and buckwheat (1.25 mg kg-1), magnesium-in goldenrod (29.6 mg kg-1) and iron-in linden flower (2.11 mg kg-1) and goldenrod (2.00 mg kg-1) honeys. The content of arsenic, cadmium and lead did not exceed the permissible values, i.e. 0.20, 0.03 and 0.30 mg kg-1. The correlation analysis performed on the concentrations of the metals in the honeys demonstrated that manganese was positively correlated with copper and nickel, while iron correlated with zinc. Najwiêksze podobieñstwo, jeoeli chodzi o kumulacjê metali, wykaza³y miody rzepakowy i akacjowy oraz wielokwiatowy i naw³ociowy. Wykorzystuj¹c ten fakt do bioindykacji ska¿enia oerodowiska, nale¿a³oby zweryfikowaae go na materiale pochodz¹cym z obszarów, gdzie wy-st¹pi³yby ró¿nice w zawartooeci metali szczególnie niebezpiecznych, zw³aszcza kadmu i o³owiu.
