| 英文摘要 | PM2.5 samples were collected during summer and winter in Wangzhou, a mountainous city in Three Gorges Reservoir, China. Organic carbon (OC) and elemental carbon (EC) were analyzed by thermal optical reflection (TOR) and investigated for their pollution characteristics and sources. The average concentrations of OC and EC were (7.09±1.86) μg·m-3 and (3.49±0.64) μg·m-3 in summer, higher than that in winter of (16.82±6.87) μg·m-3 and (6.21±2.06) μg·m-3, respectively. This may be related to biomass burning by local residents. The concentrations of OC in PM2.5 were significantly correlated with EC in winter (r=0.89), suggesting that they might have similar primary sources. The correlations between TC and K+ in PM2.5 were stronger in winter (r=0.88) than summer (r=0.69), suggesting biomass burning contributed significantly to the carbon pollution. The concentrations of secondary organic carbon (SOC) were estimated by OC/EC ratio method. The average concentration of SOC was (2.17±1.46) μg·m-3 in summer and (4.46±3.69) μg·m-3 in winter, contributed 28.18%±13.85% and 23.13%±12.30% to total OC, respectively. By calculating and analyzing the abundances of eight kinds of carbon components in PM2.5, motor vehicle emissions and biomass burning were indicated to be the major sources of carbon components in Wanzhou. ©, 2015, Science Press.
