“…The AAE of wood burning emissions (AAE wb ) is commonly reported in a range that extends from about 1 to upwards of about 5 [10,11,14,27], while the AAE of emissions from fossil fuel sources (AAE ff ) appears to be less variable and has been observed close to 1 [11]-as is expected for aerosols comprised of nearly pure BC. Residential heating and recreational fires [28] are the main local wood combustion sources.…”

“…AAE wb and AAE ff values vary by the nature of the sources that produce an aerosol sample [27], as factors like fuel type, characteristics of the combustion event and technology, and atmospheric aging will affect the refractory properties of an aerosol. It is thus important to consider the specific local and regional combustion sources when selecting AAE wb and AAE ff values for analysis.…”

Black carbon (BC) or soot contains ultrafine combustion particles that are associated with a wide range of health impacts, leading to respiratory and cardiovascular diseases. Both long-term and short-term health impacts of BC have been documented, with even low-level exposures to BC resulting in negative health outcomes for vulnerable groups. Two aethalometers—AethLabs MA350 and Aerosol Magee Scientific AE33—were co-located at a Utah Division of Air Quality site in Bountiful, Utah for just under a year. The aethalometer comparison showed a close relationship between instruments for IR BC, Blue BC, and fossil fuel source-specific BC estimates. The biomass source-specific BC estimates were markedly different between instruments at the minute and hour scale but became more similar and perhaps less-affected by high-leverage outliers at the daily time scale. The greater inter-device difference for biomass BC may have been confounded by very low biomass-specific BC concentrations during the study period. These findings at a mountainous, high-elevation, Greater Salt Lake City Area site support previous study results and broaden the body of evidence validating the performance of the MA350.

“…For the quantification of BrC, various optical measurement techniques have been employed (Fang et al, 2022;Pani et al, 2021;Pokhrel et al, 2017;Olson et al, 2015;Martinsson et al, 2015;Bahadur et al, 2012;Zhang et al, 2020;Li et al, 2022;Sun et al, 2021;Zhang et al, 2021;Rathod and Sahu, 2022;Massabò et al, 2015). The methods commonly involve the determination of the wavelength-dependent light absorption and subtracting the inferred BC absorption at 65 specific wavelengths.…”

Abstract. Residential biomass combustion significantly contributes to light-absorbing carbonaceous aerosols in the atmosphere, impacting the Earth's radiative balance at regional and global levels. This study investigates the contribution of brown carbon to the total particulate light absorption in the wavelength range of 370 to 950 nm (BrC370-950) and the particulate absorption Ångström exponents (AAE470/950) in 15 different European residential combustion appliances using a variety of wood-based fuels. BrC370-950 was estimated to be from 1 % to 21 % for wood log stoves and was primarily influenced by fuel moisture content and minimally affected by combustion appliance type. The BrC370-950 contribution was 10 % for a fully automatized residential pellet boiler. Correlations between the ratio of organic to elemental carbon (OC/EC) and BrC indicated that a one unit increase in OC/EC corresponded to approximately a 14 % increase in BrC370-950. Additionally, BrC370-950 increased with decreasing combustion efficiency. AAE470/950 of wood log combustion aerosols ranged from 1.06 to 1.61. By examining the correlation between AAE470/950 and OC/EC, an AAE470/950 close to unity was found for pure black carbon (BC) particles originating from residential wood combustion. This supports the common assumption used to differentiate light absorption caused by BC and BrC. Moreover, diesel aerosols exhibited an AAE470/950 of 1.02, with BrC370-950 contributing only 0.66 % to the total absorption, aligning with the assumption employed in source apportionment. These findings provide important data to assess the BrC370-950 of RWC emissions with different emission characteristics and confirm that BrC can be a major contributor to particulate UV and near-UV light absorption for Northern European wood stove emissions with relatively high OC/EC ratios.

This work evaluates Black Carbon emissions produced in Ciudad Valles, San Luis Potosí, México, during the harvest 2020–2021 of Ingenio Plan de Ayala and its association with the sugarcane sector in its area of influence. Black Carbon concentrations were measured each hour by the 7-wavelength aethalometer (AE-33) from November 13, 2020, to June 7, 2021, at Tecnológico Nacional de México - Campus Ciudad Valles, located northeast of the city, approximately 1 kilometer from Ingenio and bordered by the sugarcane area. The maximum daily concentration recorded was 4.5 ± 0.072 µg m− 3 with a daily average of 0.9 ± 0.014 µg m− 3, enough to increase the mortality of the long-term exposed population by almost 6.0% moreover, according to the World Health Organization, and to cause environmental and productive effects. The burning of fossil fuels represented 62.9% of the total Black Carbon, indicating that contrary to official statistics, Ingenio Plan de Ayala may continue using fuel oil. Likewise, there was a statistically significant difference in Black Carbon concentrations during harvest and no harvest periods, indicating a direct relationship between its emissions and the sugarcane sector of this region. The highest concentrations were in the surrounding area of Ingenio Plan de Ayala and sugarcane lands, which supports the previous theory. With the results obtained, the bottom line is that evaluating other agricultural burning emissions near the growing cities is necessary to minimize adverse effects on human health and reduce CO2eq emissions.
