摘要

气候变化正在增加极端天气事件的频率，如植被火灾。植被火灾排放的排放物含有大量影响地球系统和人类健康的有机化合物。本文综述了左旋葡聚糖（一种由纤维素和半纤维素热解产生的脱水单糖）的来源、稳定性、运输、降解和地球化学记录。在气溶胶、水、冰雪、湖泊或海洋沉积物中检测到左旋葡聚糖。对环境和地质样品中的左旋葡聚糖进行分析，可以确定植被火灾模式变化的时间节奏和详细特征，范围从单个事件到季节到年尺度，直至冰期-间冰期旋回。

Geochemistry of vegetation fires using levoglucosan: a review

Climate change is increasing the frequency of extreme weather events such as vegetation fires. Vegetation fires emissions contain numerous organic compounds that impact the Earth system and human health. Here, we review the sources, stability, transport, degradation and geochemical records of levoglucosan, a dehydration monosaccharide produced by the pyrolysis of cellulose and hemicellulose. Levoglucosan has been detected in aerosols, water, snow and ice, and lake or marine sediments. Analysis of levoglucosan in environmental and geological samples enable the identification of temporal rhythms and detailed features of changes in vegetation fire patterns, ranging from individual events to seasonal to annual scales, up to glacial-interglacial cycles.

期刊介绍： Environmental Chemistry Letters explores the intersections of geology, chemistry, physics, and biology. Published articles are of paramount importance to the examination of both natural and engineered environments. The journal features original and review articles of exceptional significance, encompassing topics such as the characterization of natural and impacted environments, the behavior, prevention, treatment, and control of mineral, organic, and radioactive pollutants. It also delves into interfacial studies involving diverse media like soil, sediment, water, air, organisms, and food. Additionally, the journal covers green chemistry, environmentally friendly synthetic pathways, alternative fuels, ecotoxicology, risk assessment, environmental processes and modeling, environmental technologies, remediation and control, and environmental analytical chemistry using biomolecular tools and tracers.
