Exposure to mobile phone (900-1800 MHz) during pregnancy: tissue oxidative stress after childbirth. med./bio.

Published in: J Matern Fetal Neonatal Med 2018; 31 (10): 1298-1303

Aim of study (acc. to author)

The effects of exposure of mice during pregnancy to a 900-1800 MHz electromagnetic field on oxidative stress in different organs of dams and the offspring should be investigated.

Background/further details

Pregnant mice (n=64) were divided into an exposure group and a control group (groups sizes not stated). After birth, 5 dams and 5 newborn animals were killed and their organs were investigated.

Main outcome of study (acc. to author)

Overall, significantly increased malondialdehyde levels were found in several organs of exposed dams and newborn animals compared to animals of the control group, while the total thiol content and the superoxide dismutase and catalase enzyme activities were significantly decreased in several organs of dams and their offspring compared to animals of the control group.
The authors conclude that exposure of mice during pregnancy to a 900-1800 MHz electromagnetic field might induce oxidative stress in different organs of dams and the offspring.
