Abstract
The content of heavy metals, non-etherified and anionic forms of fatty acids, and also fatty acids of common lipids in honeycomb cells, obtained from hives placed in areas with high, medium and low levels of technogenic loading is investigated. The hives were located at the educational apiary of Lviv National University of Veterinary Medicine and Biotechnologies named after S.Z. Gzhytskyj (area with very heavy traffic and industrial activity) and in private beekeeping farms in the town Vynnyky and the village Chyzhyky, Pustomyty district, Lviv region (areas with lower intensity of traffic and industrial activity). Our research has shown that the newly-built honeycomb cells obtained from hives placed in the territory with medium and low levels of technogenic loading contain a lower quantity of such heavy metals as iron, zinc, cuprum, chromium, nickel, lead and cadmium. The total amount of non-etherified fatty acids with even and odd number of carbon atoms in the chain, monounsaturated fatty acids of n-7 and n-9 families and polyunsaturated fatty acids of n-3 and n-6 families was higher in these honeycombs. However, the total concentration of anionic forms of fatty acids with even and odd number of carbon atoms in the chain, monounsaturated fatty acids of n-7 and n-9 families and polyunsaturated fatty acids of n-3 and n-6 families was lower in these honeycombs. Due to the above-mentioned monounsaturated and polyunsaturated fatty acids the amount of fatty acids of common lipids rises. It leads to increase in the antibacterial and antifungal properties of honeycomb cells and reduction of fragility of their walls. The greatest changes in concentration of heavy metals, non-etherified and anionic form of fatty acids, and also fatty acids of common lipids occur in the newly built honeycomb cells in the territory with low technogenic loading on the environment.
Highlights
Intensive development of the chemical industry and agriculture, environmental degradation and pollution by heavy metals causes growth of toxic lesions in humans and animals
It is ascertained that in the honeycombs, obtained from beehives located in areas with medium and low technogenic loading, compared with the honeycombs, selected from hives that are kept in a high level of anthropogenic impact the level of iron, zinc, copper, chromium, nickel, lead and cadmium is likely to be reduced (Table 1)
In the newly built honeycombs obtained from the beehives located in the areas with medium and low technogenic loading compared to the honeycombs received from the beehives located in the areas with high anthropogenic impact the concentration of the major saturated fatty acids of total lipids with even number of carbon atoms in the chain decreases
Summary
Intensive development of the chemical industry and agriculture, environmental degradation and pollution by heavy metals causes growth of toxic lesions in humans and animals. One feature of heavy metals is that in small amounts almost all of them are necessary for plants and organisms (Kulbachko et al, 2011; Brygadyrenko and Ivanyshyn, 2014, 2015; Tsvetkova et al, 2016). Some heavy metals (mercury, cadmium, lead) are distinguished by a special feature of toxicity (Vymazal and Březinová, 2016). The development of industry, agriculture, energy and transport, intensive mining all lead to an increase of the concentrations of heavy metals in the air, water, soil, plants and plant pollen (Conti and Botrè, 2001; Wang Haiyan and Arne, 2003; Pashayan, 2006; Vikram Reddy еt al., 2013). Heavy metals are rapidly accumulated in the tissues of honey bees and honeycombs (Bogdanov, 2006; Perugini еt al., 2011)
