Abstract

To investigate the public health, risk perception (RP) and negative feeling (NF) effects of power frequency electromagnetic fields (PF-EMF), a survey was conducted among 615 residents near 16 operating 110~500kV high-voltage transmission lines (HVTLs). Relative exposure intensity of PF-EMF was calculated by running parameters of HVTLs. The differences of health effects between respondents inside 50m and outside 50m from the center of HVTLs were analyzed, as well as the mean difference of RP and NF of respondents near HVTLs with different exposure intensity of PF-EMF, voltage level and types of tower. Optimal regression models were established through multiple linear stepwise regression analysis to estimate RP of and NF to PF-EMF. Results showed that the health effects of PF-EMF had a relative risk of 0.87 for respondents inside 50m compared with outside 50m from the center of HVTLs. In the scope of PF-EMF of this survey, i.e., E<0.35kV/m and B<0.80 μT, the public RP and NF were slightly influenced by PF-EMF exposure intensity, while greatly influenced by size of HVTLs, types of tower, health status and etc.
