Studiul conţinutului micro-, mactoelementelor şi prezenţa metalelor grele în componenţa polenului

Abstract

Quality and biological value of bee products depends largely on the maintenance conditions of bee families. Our research was conducted to determine the micro- and macroelements content, and heavy metals in the composition of pollen. It was established that the composition of pollen dry mass is 85.89- 93.06% absolutely dry 82.68 - 86.90%, initial water is 6.94 - 14.11%, hygroscopic 2.90- 6.98% total from 13.10 to 19.54%. It revealed that the total amount of studied elements in pollen composition is from 53.2 to 95.1 mg / kg, of which Mn from 11.1 to 29.6 mg / kg, Cr 0.5 - 0.9 mg / kg, Co 1.0 mg / kg, Zn from 28.6 to 47.3 mg / kg, Cu 9.7 to 16.4 mg / kg. It was found that in the composition of pollen macroelements consist 11,810.2 to 15,140.4 mg / kg, of which Ca from 1480 to 3304.6 mg / kg, Mg 652.8 to 1532.8 mg / kg, Fe 49.8-190, 3 mg / kg, K 3450-6750 mg / kg, Na 29.4 to 61.0 mg / kg, P2O5 4117-7680 mg / kg. It was established that in the composition of the pollen heavy metals consist from 41.34 to 50.08 mg / kg, of which Pb 0.23 to 0.68 mg / kg, Cd from 0.07 to 0.12 mg / kg. The amount of micro, and macroelements and heavy metals in pollen is not identical and depend largely on their origin and period of collection. The richest in micro-and macroelements is pollen collected during spring.
