Effect of an 1800 MHz electromagnetic field emitted during embryogenesis on the blood picture of one-day-old domestic hen chicks (Gallus gallus domesticus)

Anotace: Exposure to artificial electromagnetic fields emitted mainly by mobile telephony has been steadily increasing with the development of modern technology. Haematological indices are among the most common indicators of the body’s physiological status. The aim of the study was to determine the effect of an 1800 MHz electromagnetic field emission on the blood picture of one-day-old domestic hen chicks. During the experiment, chick embryos were exposed to artificial electromagnetic fields throughout incubation for 13 ´ 2 min/day, 4 ´ 10 min/day and 1 ´ 40 min/day. After hatching, blood was collected from 10 one-day-old chicks from each group to determine: red blood cell count, haemoglobin concentration, haematocrit, mean corpuscular volume, mean corpuscular haemoglobin, mean corpuscular haemoglobin concentration, white blood cell count, and leukocyte differential count. In addition, the heterophil/lymphocyte ratio was calculated. The present study is probably the first to show an increase in the red blood cell count, haemoglobin concentration, haematocrit, white blood cell count, segmented heterophils and the heterophil/lymphocyte ratio, and a decrease in lymphocyte percentage of embryos exposed to an 1800 MHz electromagnetic field. The observed changes may be indicative of the stress-inducing effect of EMF on living organisms.
