Abstract

Influence of Electromagnetic Field with Frequency of 50 Hz in form of Doses on Selected Biochemical Markers of Honey Bee Plotnik M, Bieńkowski P, Berbeć E, Murawska A, Latarowski K, Migdał P. Influence of Electromagnetic Field with Frequency of 50 Hz in form of Doses on Selected Biochemical Markers of Honey Bee. Journal of Apicultural Science. 3923;67(1): 27-36. doi: 10.2478/jas-2023-0003. Abstract The honey bee has a significant environmental and economic impact. While collecting food or water, bees are exposed to negative physical and chemical factors that lead to physiological and behavioral changes and, consequently, even death. Along with the development of technology and communication, electromagnetic fields produced by artificial emitters have begun to have an impact on the environment. The aim of the study was to check whether the electromagnetic field also impacts antioxidant enzymes functioning in the honey bee’s organism. The study was conducted under laboratory conditions, and one-day and seven-day-old honey bee workers were used in the experiment. Honey bee workers were exposed to an electromagnetic field with a frequency of 50Hz and variable intensity in the range of 1-10 kV/m. Immediately after the end of the exposure, hemolymph was collected from the bees for biochemical analysis. The results of the research did not show clearly whether changes in the activity of biochemical markers were affected by the time spent in the electromagnetic field orits intensity but did show that there was a difference in physiology between one-day-old and seven-day-old bees.

Main findings

Honey bee workers were exposed to a 50 Hz electromagnetic field with variable intensity (1–10 kV/m). Results did not clearly show whether changes in biochemical marker activity were affected by exposure time or field intensity, but did show physiological differences between one-day-old and seven-day-old bees.

Outcomes measured

  • Activity of antioxidant enzymes/selected biochemical markers in hemolymph

Limitations

  • Sample size not reported in abstract
  • Exposure duration/time in field not specified in abstract
  • Results described as not clearly attributable to exposure time or intensity
  • Laboratory conditions may limit generalizability to field exposures
