Electric cars have been announced for the big cities of the environmental panacea.
However, new studies conducted in China have shown that electric vehicles generally have higher polluting effect and may be more harmful to health than regular trucks.
The study of pollution in 34 Chinese cities found that electricity generated by power stations and supply electric vehicles leads to a greater release of fine particles emissions than gasoline vehicles.
Assistant professor of civil and environmental engineering graduate student Chris Cherry and Shuguang Ji analyzed the emissions and environmental health impacts of five vehicle technologies, focusing on dangerous fine particles.
They found that the electricity supply for the electric machinery is more particulate contamination than the same number of gasoline-fueled cars.
Solids derived from the combustion of fossil fuels and include acids, organic matter, metals and particle dust.
Professor Cherry says: "The common assumption was that the air quality and health impacts for electric vehicles are lower than for conventional vehicles. Our results contradict this. "
