Abstract
Recent predictions from the World Health Organization indicate urban air pollution is the cause of nearly four million deaths annually. In particular, diesel soot, abundant in ultrafine (nanoscale) size, is shown to be carcinogenic and affects the cardiovascular and respiratory systems. Diesel soot contains mainly black carbon and adsorbed carcinogenetic substances as PAHs. Furthermore, soot and methane are both recognized as remarkable greenhouse-effect drivers. In its 65th General Assembly, the World Medical Association (WMA) recommended a series of measures to its member organizations to follow through via their respective governments. The recommended measures include utilizing the best available technology (BAT) for all new diesel vehicles and soot-filter retrofits for all in-use engines, curbing on nanosize soot emission, and further scrutiny of health impacts due to ultrafine particles, instilling further preventing measures and public awareness programs, protection against ultrafine particles in aircraft cabins, trains and alike, and to shift urban traffic to public transportation systems.
