“Research consistently links traffic emissions to negative effects on both the environment and human health. “Whether it be cancer, respiratory problems, cardiac problems or neurodegenerative problems, there are numerous adverse health effects associated with the chemicals in these emissions,” said Evans. “If we were able to reduce emission of pollutants like black carbon, we would also see an immediate climate benefit.” Black carbon — commonly called soot — is a marker for exposure to diesel exhaust which is known to have negative health effects.”
