英文摘要 | Ambient PM2.5 samples were collected in suburban area of Zhengzhou, China to investigate the impact of straw open burning on local aerosol during wheat harvest season in 2015. Secondary formation and accumulation processes were found under unfavorable meteorological conditions through the chemical composition analysis in PM2.5. And spatial and temporal variation of the agricultural activities were observed through MODIS fire spots data combined with back trajectory analysis. Results showed elevated levoglucosan was affected directly during biomass burning episodes and transportation periods. In order to estimate the contribution, levoglucosan/K+ combined with levoglucosan/mannosan were analyzed to identify biomass burning sources. And the results showed that levoglucosan were emitted from straw burning mixing with softwood combustion during the study period, emphasizing that wood combustion for households was non-negligible which consists part of the levoglucosan background in Zhengzhou aerosol. Based on emission factors (levoglucosan/OC or levoglucosan/PM2.5) summarized by laboratory simulation experiments, the study period was divided into 7 depending on the former characteristics to estimate the contribution of biomass burning to aerosol, and the average contributions of biomass burning emission to OC and PM2.5 were 46% and 13% relatively, indicating biomass burning have a significant impact on ambient aerosol levels during harvest season. |
