この研究は、900MHz GSM電磁界ばく露によるヒト末梢血単核細胞(単球およびリンパ球)での酸化ストレス誘導および細胞内の活性酸素種(ROS)レベルの変化を調べた。健康なボランティア(n=13:21-30歳)から採取した末梢血の試料(6ml)をそれぞれ2分し、一方は携帯電話シミュレータから放射されるRF電磁界に2時間ばく露し、他方は対照(無ばく露)とした。ばく露後に各試料から単核細胞を遠心分離し、単球およびリンパ球の細胞内ROS含有量を測定した。その結果、単球の豊富な試料では、ばく露群でのROS産生の有意な増加が見られた;リンパ球の豊富な試料では、このような影響は見られなかった、と報告している。

The effects of exposure of human blood samples to a 900 MHz electromagnetic field (GSM) on oxidative stress in monocytes and lymphocytes should be investigated.
Blood samples were obtained from 13 healthy volunteers. Each sample was divided and one half was assigned to an exposure group (group 1) and the other half to a control group (group 2). After exposure, enriched fractions of monocytes and lymphocytes were investigated, respectively.
A positive control was conducted.

ばく露装置の詳細 | the signal was generated by a GSM simulator and transferred to a rectangular waveguide made of aluminum by a co-axial wire; the samples were placed at a location with maximum electric and magnetic fields in the waveguide to provide a relatively homogeneous field for exposure; the increase of temperature was not more than 0.1°C |

Monocytes in the exposure group (group 1) showed a significantly increased content of reactive oxygen species compared to the control group (group 2). No significant differences between both groups were found in lymphocytes.
The authors conclude that exposure of human blood samples to a 900 MHz electromagnetic field (GSM) might induce oxidative stress in monocytes, although the consequences for health are not clear.
