Abstract To better understand the pollution characteristics of black carbon (BC) in Shenzhen, BC and meteorological factors were measured from January 1, 2014 to June 30, 2015 at XC (suburban site) and ZZL (urban site) in Shenzhen. The results showed the average mass concentrations of BC at XC and ZZL sites during the campaign were (1.12±0.90) μg/m³ and (2.58±2.00) μg/m³ respectively. The background concentrations of BC at the two sites were (0.27±1.31) μg/m³ and (1.07±0.85) μg/m³ respectively. The σ_abs at XC site was (5.87±4.81) Mm^-1 while at ZZL site was (13.47±10.50) Mm^-1. It was found that the values at the urban site were much higher than those at the suburban site. The BC concentrations at both sites were following the logarithmic normal distribution with higher concentrations in the dry season than that in the rainy season. A distinct diurnal pattern of BC with two peaks was observed at ZZL site. In contrast, XC site did not show obvious diurnal variations. The Absorption Angstrom Exponent (AAE) can be considered as an indicator of BC mixing state. It was found to be close to 1at both sites, indicating that BC at the two sites were dominated by fossil fuel combustion. Further study suggested high BC concentrations at XC site were usually associated with northwest wind (10~20m/s) when polluted aerosols were transported from the Shenzhen container wharf, which is the world's third largest container terminal. The backward trajectories clusters analysis indicated that BC at XC site was mainly affected by the long-range transport. WhileBC at the ZZL site was affected by the surrounding areas and local emissions.

Key words： BC Shenzhen mass concentration AAE
