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.
烟雾事件是由不受控制的生物质燃烧（BB）引起的，包括森林和泥炭火灾，继续在东南亚（SEA）发生，影响空气质量、大气能见度、气候、生态系统、水文循环和人类健康。烟雾中的主要污染物是空气中的颗粒物（PM）。从 2010 年到 2020 年，SEA 进行了许多基础实验室、现场和建模研究，以调查 BB 诱导的 PM 对环境和健康的潜在影响。本综述的目的是根据 2010 年至 2020 年发表的 127 篇研究论文，汇集我们对 BB 衍生 PM 各个方面的最新认识，这些论文在以前的综述中没有涉及。具体来说，本文讨论了 BB 衍生 PM 的物理、化学、毒理学和辐射特性。它还提供了对 BB 衍生 PM 的环境和健康影响的深入了解，总结了在 BB 事件期间进行 PM 源分配的方法，并讨论了减轻对 BB 衍生 PM 的暴露。概述了未来研究重点的建议。强调了防止东南亚地区未来发生 BB 事件所需的政策。
