Biomass burning is one source of air pollution that emits soot, smoke, particulate matter, free radicals and other substances, affecting human health, air quality, cloud formation processes and climate change. During biomass burning, organic biomass burning tracers are emitted, such as levoglucosan and its isomers mannosan and galactosan, which are formed at temperatures above 300 °C during cellulose and hemicellulose pyrolysis. The objective of this research is the measurement of biomass burning tracer concentrations in PM 10 samples in Krynica during two winter seasons from 01.12.2017 to 31.03.2018 and from 01.12.2018 to 26.03.2019. The average concentrations of organic carbon were 9.48 μg/m 3 in the 2017/2018 season and 8.79 μg/m 3 in the 2018/2019 season. The average concentration of levoglucosan in the PM 10 samples in 2017/2018 was 137 ng/m 3 , while in 2018/2019, the average concentration reached 245 ng/m 3 . Levoglucosan was the dominant compound among the determined biomass burning tracers, accounting for 88.6% in 2017/2018 and 72.4% in 2018/2019. The conducted measurements show that the levoglucosan to mannosan ratio was equal to 10.5 and 3.9 in 2017/2018 and 2018/2019, respectively. The biomass smoke organic carbon was approximately 10.6% in 2017/2018 and 20.5% in 2018/2019. These results correspond to the contribution of biomass smoke to organic carbon, which was equal to 14.4% and 28.4% in the 2017/2018 and 2018/2019 seasons, respectively.

Krynica Zdrój 两个冬季生物质燃烧示踪剂浓度的比较

生物质燃烧是一种空气污染源,会排放烟尘、烟雾、颗粒物、自由基和其他物质,影响人类健康、空气质量、云形成过程和气候变化。在生物质燃烧过程中,会排放有机生物质燃烧示踪剂,例如左旋葡聚糖及其异构体甘露聚糖和半乳糖,它们是在纤维素和半纤维素热解过程中在 300°C 以上的温度下形成的。本研究的目的是在 01.12.2017 至 31.03.2018 和从 01.12.2018 至 26.03.2019 的两个冬季期间测量 Krynica 的 PM 10 样品中的生物质燃烧示踪剂浓度。2017/2018 季节有机碳的平均浓度为 9.48 μg/m 3 ,2018/2019 季节为 8.79 μg/m 3 。2017/2018年PM 10 样品中左旋葡聚糖的平均浓度为137 ng/m 3 ,而2018/2019年平均浓度达到245 ng/m 3 。左旋葡聚糖是确定的生物质燃烧示踪剂中的主要化合物,占 2017/2018 年的 88.6% 和 2018/2019 年的 72.4%。进行的测量表明,2017/2018 年和 2018/2019 年,左旋葡聚糖与甘露聚糖的比率分别等于 10.5 和 3.9。2017/2018 年生物质烟有机碳约为 10.6%,2018/2019 年约为 20.5%。这些结果对应于生物质烟雾对有机碳的贡献,在 2017/2018 和 2018/2019 季节分别等于 14.4% 和 28.4%。左旋葡聚糖是确定的生物质燃烧示踪剂中的主要化合物,占 2017/2018 年的 88.6% 和 2018/2019 年的 72.4%。进行的测量表明,2017/2018 年和 2018/2019 年,左旋葡聚糖与甘露聚糖的比率分别等于 10.5 和 3.9。2017/2018 年生物质烟有机碳约为 10.6%,2018/2019 年约为 20.5%。这些结果对应于生物质烟雾对有机碳的贡献,在 2017/2018 和 2018/2019 季节分别等于 14.4% 和 28.4%。左旋葡聚糖是确定的生物质燃烧示踪剂中的主要化合物,占 2017/2018 年的 88.6% 和 2018/2019 年的 72.4%。进行的测量表明,2017/2018 年和 2018/2019 年,左旋葡聚糖与甘露聚糖的比率分别等于 10.5 和 3.9。2017/2018 年生物质烟有机碳约为 10.6%,2018/2019 年约为 20.5%。这些结果对应于生物质烟雾对有机碳的贡献,在 2017/2018 和 2018/2019 季节分别等于 14.4% 和 28.4%。
