In recent years, on a global scale, more and more reports of a phenomenon called CCD (Colony Collapse Disorder) have been reported. In addition to pesticides, diseases, and other environmental stressors, electromagnetic fields are also mentioned as one of the possible causes of CCD. One of the body’s first lines of defense against harmful factors is the antioxidant system. We hypothesized that electromagnetic field upregulate the activity of SOD (superoxide dismutase), CAT (catalases), and changed FRAP (total antioxidant potential) in honeybee hemolymph. In our research, 12 h bee’s exposure to E-field was analyzed to determine changes in the antioxidant system. The frequency of 50 Hz and various intensities were used: 5.0 kV/m, 11.5 kV/m, 23.0 kV/m, and 34.5 kV/m. Superoxide dismutase was characterized by four times higher activity in the study groups as compared to the control group. Catalase activity in all groups was characterized by statistically significantly different activity between the groups. The highest activity was recorded in the 34.5 kV/m group. The lowest activity was recorded in the 11.5 kV/m group. A relationship was found between different E-field intensities and changes in the antioxidant system.

暴露于50 Hz电磁场频率和可变强度的12 h后，蜜蜂抗氧化剂系统的变化

近年来，在全球范围内，已经报道了越来越多的关于称为CCD（殖民地崩溃障碍）的现象的报道。除了农药，疾病和其他环境胁迫因素外，电磁场也是引起CCD的可能原因之一。人体抵御有害因素的第一道防线是抗氧化系统。我们假设电磁场上调了蜜蜂血淋巴中的SOD（超氧化物歧化酶），CAT（分解酶）和FRAP（总抗氧化能力）。在我们的研究中，分析了蜜蜂在电场中暴露12 h的情况，以确定抗氧化剂系统的变化。使用50 Hz的频率和各种强度：5.0 kV / m，11.5 kV / m，23.0 kV / m和34.5 kV / m。研究组中超氧化物歧化酶的活性是对照组的四倍。所有组中的过氧化氢酶活性的特征在于组之间的统计学上显着不同的活性。在34.5 kV / m组中记录到最高的活性。在11.5 kV / m组中记录的最低活性。发现不同的电场强度与抗氧化剂系统的变化之间存在关系。
