Comparison of charged nanoparticle concentrations near busy roads and overhead high-voltage power lines (Abstract, E.R. Jayaratne, X. Ling, L. Morawska, May 28, 2015)
Also discussed here: Roadside air can be more charged than under a high-voltage power line (Science Daily, May 28, 2015)
Today we review research from Brisbane, Australia, comparing the number of charged particles emitted by vehicles near highways to what is found under power lines. Results indicate more than twice as many charged vehicles near roads. The charges alone do not present a health hazard but the fact that the particulates are charged means that they adhere more closely to the lungs when they are breathed in – and this as earlier research has shown presents a number of health impacts which would be increased by the electrical charging.
