Mineral element and heavy metal (cadmium, lead and arsenic) levels of bee pollen in Turkey

Abstract

In this study, mineral element and heavy metal levels in bee pollen produced in various regions of Turkey (20 samples) and imported bee pollen (4 samples), were determined using an Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) device. Mineral and heavy metal levels of bee pollens produced in Turkey were determined to be within the following ranges (minimum-maximum, mu g/g(pollen)); Cr (chromium): 0.124-1.595, Cu (copper): 3.728-14.994, Fe (iron): 28.603-725.360, Mg (magnesium): 271.107-1278.340, Mn (manganese): 8.151-201.036, Se (selenium): 0.593-5.085, Zn (zinc): 14.832-39.079, B (boron): 0.592-61.33, Ni (nickel): 0.002-1.761, Si (silicon): 0.082-10.500, K (potassium): 992.107-2894.154, Ca (calcium): 491.853-1472.102, P (phosphorus): 795.899-5246.992 and Cd (cadmium): 0.006-0.181, Pb (lead): 0.000-0.479, As (arsenic): 0.006-1.035. As a result of this study, it can be concluded that bee pollens produced in Turkey may be a good source of mineral regarding the trace elements Se, Mn, Fe, Cr and Cu.
