Short summary
To characterize primary emissions over the eastern coast of China, a series of field campaigns were conducted. The high loadings of both BC and CO implied severe anthropogenic pollution over the areas. The slopes between BC and CO at different areas revealed the vehicular emission as the common source and the distinct fuel structures between North and South China. The comparisons of slopes and correlation coefficient among these areas can indicate the aging extent of BC at the macroscopic level.
