Smoke haze episodes, resulting from uncontrolled biomass burning (BB) including forest and peat fires, continue to occur in Southeast Asia (SEA), affecting air quality, atmospheric visibility, climate, ecosystems, hydrologic cycle and human health. The pollutant of major concern in smoke haze is airborne particulate matter (PM). A number of fundamental laboratory, field and modeling studies have been conducted in SEA from 2010 to 2020 to investigate potential environmental and health impacts of BB-induced PM. The goal of this review is to bring together the most recent developments in our understanding of various aspects of BB-derived PM based on 127 research articles published from 2010 to 2020, which have not been conveyed in previous reviews. Specifically, this paper discusses the physical, chemical, toxicological and radiative properties of BB-derived PM. It also provides insights into the environmental and health impacts of BB-derived PM, summarizes the approaches taken to do the source apportionment of PM during BB events and discusses the mitigation of exposure to BB-derived PM. Suggestions for future research priorities are outlined. Policies needed to prevent future BB events in the SEA region are highlighted.

烟霾事件，包括森林和泥炭大火在内的不受控制的生物质燃烧（BB）造成的后果，在东南亚（SEA）继续发生，影响了空气质量，大气能见度，气候，生态系统，水文循环和人类健康。烟霾中主要关注的污染物是空气中的颗粒物（PM）。从2010年到2020年，在SEA中进行了许多基础实验室，现场和模型研究，以研究BB诱发的PM对环境和健康的潜在影响。这篇综述的目的是基于我们从2010年到2020年发表的127篇研究文章，汇总我们对BB衍生PM各个方面的理解的最新进展，而在以前的评论中并未传达。具体而言，本文讨论了BB衍生的PM的物理，化学，毒理学和辐射特性。它还提供了对BB来源的PM的环境和健康影响的见解，总结了在BB事件期间进行PM来源分配的方法，并讨论了减少BB来源的PM暴露的方法。概述了未来研究重点的建议。重点介绍了防止在SEA区域发生未来的BB事件所需的政策。
