Abstract

Analysis of elements content in honey is important for honey quality and safety and for monitoring of environmental pollution. The levels of 22 elements, aluminum (Al), barium (Ba), calcium (Ca), cadmium (Cd), chromium (Cr), cobalt (Co), iron (Fe), copper (Cu), potassium (K), magnesium (Mg), manganese (Mn), nickel (Ni), sodium (Na), lead (Pb), strontium (Sr), silver (Ag), bismuth (Bi), gallium (Ga), indium (In), lithium (Li), thallium (Tl) and zinc (Zn), were determined in 70 samples obtained from beekeepers located in the West Mediterranean region of Turkey. Determination of elements content was carried out using ICP-OES. Chromium, Co, Cd, Ag, Bi, In and Tl were not detected in any of the tested honey samples. The most abundant metal was K which has an overall average of 764.26 mg kg-1. Higher concentrations of Pb, Ni, Mg, Na, K and Mn were found in the samples obtained from Burdur compared to other provinces. The levels of Cu were statistically lower in Antalya in comparison to other regions. No significant differences were observed in Al, Zn, Fe, Sr, Ba, Ca and Ga levels between regions. The differences in the chemistry of honey samples collected from different regions may be due to geochemical soil composition and geographical differences. Their levels were below to the European limits and the honeys are safe for human consumption.
