Cows salivary cortisol levels were measured on 17 dairy farms in Bavaria under exposure to radiofrequency electromagnetic fields of mobile phone networks.
Background/further details:
Data are intended to give an impression of the stress situation of the animals (via cortisol secretion). The investigation differentiated between low-exposure and high-exposure farms. Five cows per farm were treated intravenously with adrenocorticotropic hormone. By means of saliva samples a cortisol profile over four hours was then determined.
Under chronic stress situation the adrenal cortex activity is increased. Therefore, the organism response to a exogenous stressor (stimulated via ACTH administration) by an increase of the peripheral cortisol level. Endpoint Exposure
General category: digital mobile phone, GSM
FIELD View further expo parametersExposed system:
animal (species/strain): cow
whole body exposure Methods
Endpoint/Measurement parameters/Methodology investigated material: isolated bio./chem. substance (in vitro), saliva
investigation on living organism
investigated organ system: endocrine system
time of investigation: during and after exposure
Main outcome of study (according to author)
Highly exposed cows had a higher and more sustained cortisol level than animals with exposure of a lower level. Therefore it is concluded that cows with prolonged exposure to radiofrequency electromagnetic fields are chronically stressed. This could lead to a higher susceptibility to diseases.
