“…Size-resolved BB chemical composition analysis has demonstrated that the molecular tracers peak in the fine mode of ambient aerosols (Chen et al, 2014;Zhang et al, 2015). Measurements of PM emissions from ten biomass fires showed that potassium ions, chlorides, and sulfates are the dominant inorganic species in the fine mode, while calcium ions are an important component in coarse particles (Park et al, 2013).…”

Aerosol particles significantly impact the regional environment, including climate change, specifically in periods of extensive biomass burning. The major agricultural and domestic combustion emission sources were assessed in nearsource and ambient monitoring campaigns in northwestern Vietnam during the dry season. The composition and microstructure of on-field burning and cooking emissions were analyzed with a variety of techniques. A wide range of observed PM 2.5 mass concentrations was categorized according to the smoke level, supported by the evolution of carbon fractions (OC and EC) as well as ionic species and molecular tracers (K + , levoglucosan, and mannosan). The OC/EC and individual organic compound ratios on days with high smoke levels indicate smoldering combustion of softwood and other local biomass species, impacting aerosol composition at the regional level. Acid and non-acid carbonyls, carboxylates, and aliphatic carbon functionalities in the PM 2.5 size fraction evolved with increasing smoke intensity, together with carbonates in coarse (PM 1-2.5 and PM 2.5-10 ) size fractions, indicating a large impact of smoke emissions and soil lifted up by the intense fires. Biomass burning influence increased the abundance of soot and organic particles in the submicron fraction from 12% at low to 59% and 68% at moderate and high smoke levels, respectively. Smoke micromarkers of local biomass burning source emissions determined the microstructure of ambient aerosols representative for northern Southeast Asia.

“…K has been widely used as a tracer for biomass burning. Besides, higher mass fractions of K, Cl and SO 4 2-were observed in the ultrafine particles from combustion of biomass materials (Park et al, 2013). Na and Ca can be mixed in particles internally when they are transported from biomass burning regions .…”

“…Moreover, size distributions of elements in size-fractionated particles can help to solve the collinearity problem in source appointment (Tan et al, 2015). For example, Cl in coarse particles primarily originates from sea salt (Masiol et al, 2015), however, combustion process, such as biomass, coal and waste burning, is the dominant source of Cl in smaller particle (Park et al, 2013;Kumar et al, 2015;Sui et al, 2016). Compared to the crustal origin of coarse particle, Ca, K and Fe detected in fine and ultrafine particles are possibly vaporized from lubricating oil (Hays et al, 2011).…”

To investigate the characteristics of elements in size-segregated atmospheric particulates, samples were collected using a 14-stage electrical low-pressure impactor (ELPI+) at an urban site in Zhengzhou from October 1 till 25, 2016, and analyzed for 25 elements. Results show that crustal elements were concentrated in coarse particles and toxic elements were concentrated in ultra-fine particles. The size distributions of Na, Mg, Al, Si, Ca, Fe, Ti, S and Cl were uni-modal with dominant peaks in the size range of 1.43-2.14 µm or 0.295-0.487 µm. K, P, Mn and Ba exhibited bimodal distributions, and the remaining elements showed multimodal distributions. Enrichment factor, correlation and principal component analyses indicated that vehicles were the dominant source of particles. Biomass burning, coal combustion and dust also contributed to the accumulation of particles. The elemental concentrations affected by different air masses are discussed to investigate the effects of regional transport. An increase in elemental concentrations related to vehicle and coal sources was observed when air masses came from eastern areas. Furthermore, air masses from the southeast could be a major factor in air pollution for Zhengzhou during special times, such as periods of biomass burning or naked cropland. When air masses came from the northwest, the majority of elements from dust and coal combustion were lower in concentration compared with clean days, while elements originating from vehicle emissions increased.

“…Extracts were then analyzed for eight ionic species and oxalate, as well as WSOC, using ion chromatography (IC, Metrohm861), and a total organic carbon analyzer (TOC, Sievers 5310C, USA). The detailed discussions for ion concentrations can be found elsewhere (Park et al, 2013). We only described the result of WSOC by TOC in this study.…”

The study of carbonaceous aerosols in the atmosphere is critical to understand the role of aerosols in human health and climate. Using standardized thermal optical transmittance methods, organic carbon (OC), elemental carbon (EC), and water soluble organic carbon (WSOC) were determined using a combustion sampling system for four types of agricultural crop residues (rice straw, red pepper stems, soybean stems, and green perilla stems) and eight types of forest trees (pine stems, pine needles, ginkgo stems, ginkgo leaves, maple stems, maple leaves, cherry stems, and cherry leaves). The aerosol particles between 0.056 and 5.6 μm in size were analyzed using a Micro-Orifice Uniform Deposit Impactor (MOUDI). In the current study, the Carbonaceous Thermal Distribution (CTD) by carbon analyzer was discussed in order to understand the carbon fractions from the twelve types of biomass burning. Also, the concentration of OC, EC, WSOC, and water insoluble organic carbon (WIOC) detected in the emissions were described.
