Participants in this study were employees working in different sections of a thermalpower plant. A total of 102 plant workers were included in the study as the exposure group and 136 office workers were included as the control group. For statistical analysis, the exposure group was further divided into the following sub-groups: low (< 11.3 µT; n=38), medium (11.3-18.9 µT; n=33) and high ( > 18.9 µT; n=31) exposure to magnetic field and low (< 14.7 V/m; n=38), medium (14.7-27.4 V/m; n=28), and high ( > 27.4 V/m; n=36) exposure to electric fields based on the 33rd and 66th percentiles of personal exposure measurements. Blood samples were taken from all participants before the start of the work shift of the last working day of the week.
each worker stated their working and non-working spots (e.g. their places of resting and eating lunch) during a normal work shift and the amount of time they spend at each spot; measurements were conducted at these spots at a height of 1 m above ground Ievel and for 2 min; the control group was mainly exposed to electric fields and magnetic fields generated by power lines, computers and appliances at the workplaces
