| 2 | Effects of Exposure to GSM Mobile Phone Base Station Signals on Salivary Cortisol,Alpha-Amylase,and Immunoglobulin A显示文摘Objective The present study aimed to test whether exposure to radiofrequency electromagnetic fields(RF-EMF) emitted by mobile phone base stations may have effects on salivary alpha-amylase,immunoglobulin A(IgA),and cortisol levels. Methods Fifty seven participants were randomly allocated to one of three different experimental scenarios(22 participants to scenario 1,26 to scenario 2,and 9 to scenario 3).Each participant went through five 50-minute exposure sessions.The main RF-EMF source was a GSM-900-MHz antenna located at the outer wall of the building.In scenarios 1 and 2,the first,third,and fifth sessions were'low'(median power flux density 5.2μW/m^2) exposure.The second session was'high'(2126.8μW/m^2), and the fourth session was'medium'(153.6μW/m^2) in scenario 1,and vice versa in scenario 2.Scenario 3 had four'low'exposure conditions,followed by a'high'exposure condition.Biomedical parameters were collected by saliva samples three times a session.Exposure levels were created by shielding curtains.Results In scenario 3 from session 4 to session 5(from'low'to'high'exposure),an increase of cortisol was detected,while in scenarios 1 and 2,a higher concentration of alpha-amylase related to the baseline was identified as compared to that in scenario 3.IgA concentration was not significantly related to the exposure.Conclusions RF-EMF in considerably lower field densities than ICNIRP-guidelines may influence certain psychobiological stress markers. | CHRISTOPH AUGNER GERHARD W.HACKER GERD OBERFELD MATTHIAS FLORIAN WOLFGANG HITZL JORG HUTTER GERNOT PAUSER | 2010 | Biomedical and Environmental Sciences2010，23，3： | 0 |
