在大气中，生物质燃烧会与其他污染源相互作用，从而加剧空气污染。然而，它对空气污染发生和发展的影响仍然知之甚少。基于2014-2016年上海地区的实地观测，研究了生物质燃烧对大气污染事件的影响特征。结果表明，整个观测期内细颗粒物污染严重，高颗粒物污染时段主要出现在冬春季。4个研究案例表明，引发高污染事件的方式是多样的，包括本地污染源、外部输送和多个污染源的联合作用。4个高污染时段均表现出较高的K+、CO和NH3浓度，表明生物质燃烧污染的存在。生物质焚烧污染主要来自中国西北部和中国东部、东南部部分省份，生物质焚烧活动较为活跃。在高污染时段，二次无机气溶胶(SIA)在PM2.5中所占比例较大，但SIA并不总是引发高污染时段。生物质燃烧运输带来的高浓度硫酸盐和硝酸盐气溶胶也会导致高污染事件的发生。此外，生物质燃烧羽流与其他污染源的混合可促进SIA的形成，加剧空气污染。这项研究强调了生物质燃烧在高度空气污染的发生和发展中的重要作用。
In the atmosphere, biomass burning can interact with other pollution sources and thereby aggravate air pollution. However, its influences on the occurrence and development of air pollution remain poorly understood. In this study, the characteristics of air pollution episodes influenced by biomass burning was investigated based on the field observation in Shanghai from 2014 to 2016. Results indicated that the fine particle pollution was serious during the whole observation period, and the high particulate pollution episodes mostly occurred in winter and spring. Four studied cases indicated that the ways to initiate high air pollution episodes were diverse, including local pollution sources, external transport and combined interaction of multiple pollution sources. All four high air pollution episodes behaved high K+, CO and NH3concentrations, showing the existence of biomass burning pollution. And most of biomass burning pollution were from northwest China and some provinces in east and southeast China, which had active biomass burning activities. In the high pollution episodes, secondary inorganic aerosols (SIA) accounted for a large proportion of PM2.5, but SIA did not always initiate high pollution episodes. The high concentrations of sulfate and nitrate aerosols brought by the transport of biomass burning could also induce the occurrence of high pollution episodes. Also, the mixing of biomass burning plumes with other pollution sources could enhance SIA formation and aggravate air pollution. This study highlights the significant roles of biomass burning in the occurrence and development of high air pollution.
