The aim of the research is to study the influence of heavy metal migration in the trophic chain on honey quality. The content of micro-, macroelements and the presence of heavy metals were determined by atomic absorption spectrometry. It was found that the mass fraction of water in honey collected from different zones was 16.1-18.05%, invert sugar – 76.4-78.5%, sucrose content – 1.6-2.07%, diastase number – 8.0-16.59 units. Gote, hydroxymethylfurfural - 3.3-7.3 mg / kg and acidity - 1.1-2.73 milliequivalents per 100 g. It was found that the amount of manganese in acacia honey of the Central zone from rural areas was on average 0.443 mg / kg, and in urban areas - 10.657 mg / kg more, zinc, respectively - 0.520 mg / kg and 2.14 mg / kg, copper - 1.363 mg / kg and 0.137 mg / kg, iron - 1.730 mg / kg and 1.230 mg / kg. It has been established that the total amount of macroelements in different types of honey fluctuates, on average, from 483.81 mg/kg (acacia) to 1435.19 mg/kg (linden honey), and heavy metals – from 2.507 mg/kg (sunflower honey) to 3.837 mg/kg (acacia honey). During the migration of heavy metals along the trophic chain (soil – flowers of honey plants – honey – pollen pellets – propolis – body of bees), their total amount changed, in the soil it averaged 2.089 mg/kg, in flowers of honey plants it increased by 16.38 times, in honey – by 1.45 times, in pollen pellets – by 21.86 times, in propolis – by 59.13 times and in the body of bees – by 36.17 times.
