Abstract

We investigated the characteristics of charged aerosols produced by high-voltage power lines (HVPLs) to explore the effects on respiratory disease incidence among those who handle HVPLs. Charged aerosol currents (fA) and charged aerosol concentrations were measured over 24 hours at 12 sites. Aerosol currents effective levels were 2.7 times higher compared to exposed and control site. This pattern of relative enhancement at exposed sites was seen consistently in all measurements and differences was 1.7 higher at exposed sites. Correlation analysis among all important variables revealed strong positive correlations between (1) currents and concentration, (2) currents and magnetic field, (3) humidity and concentration, and (4) humidity and PM₁₀, while negative correlations were observed between (1) charged aerosol concentrations and wind velocity and (2) wind velocity and humidity. Estimated production of charged aerosols from HVPLs and found that people who work with HVPLs are highly likely to be exposed to charged aerosols.
