Влияние миграции тяжелых металлов в трофической цепи на качество пчелиного меда

Abstract

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.
