Today we summarize the results of a paper that reviewed sources of PM2.5 and PM10 in 51 countries. By far the greatest source globally is traffic-related urban air pollution which amounted to 25% of ambient PM. The highest traffic emissions come from North America, Western Europe, Turkey and the Republic of Korea. The highest industrial pollution was found in Japan, Middle East and Southern Asia, Turkey, Brazil, Central Europe, and South Eastern Asia.
