"Characterization of carbonaceous aerosols including CC (carbonate carbon), OC (organic carbon), and EC (elemental carbon) were investigated at Xi'an, China, near Asian dust source regions in spring 2002. OC varied between 8.2 and 63.7 mu g m(-3), while EC ranged between 2.4 and 17.2 mu m(-3) during the observation period," investigators in Xian, People's Republic of China report.

"OC variations followed a similar pattern to EC and the correlation coefficient between CC and EC is 0.89 (n=31). The average percentage of total carbon (TC, sum of CC, CC, and EC) in PM2.5 ...
