调查了蜂巢中重金属、非醚化和阴离子形式的脂肪酸以及常见脂肪的脂肪酸含量，这些脂肪酸来自高、中、低技术负荷地区的蜂巢。这些蜂箱位于利沃夫国立兽医和生物技术大学的教育蜂场，以S.Z.Gzhytsky(交通和工业活动非常繁忙的地区)命名，以及Vynnyky镇和利沃夫地区Pustomyty区Chyzhyky村的私人养蜂场(交通和工业活动强度较低的地区)。我们的研究显示，在中等和低水平的科技负荷下，从放置在香港境内的蜂巢获得的新建蜂窝含有较少的重金属，如铁、锌、铜、铬、镍、铅和镉。这些蜂窝中碳原子为偶数和奇数的非醚化脂肪酸、n-7和n-9家族的单不饱和脂肪酸以及n-3和n-6家族的多不饱和脂肪酸总量较高。而链上碳原子为偶数和奇数的阴离子形式的脂肪酸，n-7和n-9家族的单不饱和脂肪酸以及n-3和n-6家族的多不饱和脂肪酸的总浓度较低。由于上述单不饱和脂肪酸和多不饱和脂肪酸，常见脂肪中的脂肪酸含量上升。它可以提高蜂窝细胞的抗菌和抗真菌性能，并降低其壁脆性。重金属、非醚化和阴离子形式的脂肪酸，以及常见脂肪的脂肪酸的浓度变化最大的是在对环境的技术负荷较低的地区新建的蜂窝细胞。
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.
