Roadside air can be highly charged
A new study has found that there are far more charged particles beside busy roads than under high-voltage power lines. A study by the Queensland University of Technology (QUT) researchers found that within 10 metres of a freeway, charged particles were up to 15 times more concentrated than beneath high-voltage power lines.
Melbourne: A new study has found that there are far more charged particles beside busy roads than under high-voltage power lines. A study by the Queensland University of Technology (QUT) researchers found that within 10 metres of a freeway, charged particles were up to 15 times more concentrated than beneath high-voltage power lines.
"Although the effects of ions and charged particles generated by high-voltage power lines on human health, is still open to conjecture, there has been a lot of attention on increased exposure due to expanding power networks in urban residential areas.
However, people do not realise that a large number of charged particles in urban environments come from motor vehicle emissions," said researcher Rohan Jayaratne. The researchers found that the concentration of charged particles was higher especially when the traffic included heavy-duty diesel trucks.
