“…Due to its complex organic and mineral matrices, the separation and quantification of BC in sediments is complicated, and several procedures have been developed for specific studies (Gustafsson et al, 1997(Gustafsson et al, , 2001Song et al, 2002;Hammes et al, 2007;Han et al, 2007aHan et al, , 2007bKhan et al, 2009;Poot et al, 2009;Meredith et al, 2012;Wiedemeier et al, 2015). In the present work, the wet-chemical treatment combined with thermal/optical reflectance (TOR) detection was adopted (Han et al, 2007a(Han et al, , 2007bFang et al, 2015).…”

a b s t r a c tThe coastal margins around Southeast Asia (SE Asia) may serve as an ideal location to study the sourcesink process of sedimentary black carbon (BC) because SE Asia has been identified as one of the major BC emission source regions in the world. This study provides an extensive picture of recent regional-scale sedimentary BC sequestration in the Gulf of Thailand (GOT), a tropical marine system in SE Asia. Generally, the sedimentary BC concentrations (0.07e3.99 mg/g) were in the low to moderate ranges of those obtained in other coastal sediments around the world. Regional variability of the BC and its correlation with the sediment grain size and total organic carbon (TOC) content indicated a general hydrodynamic constraint on BC occurrence in the lower Gulf in contrast to the upper Gulf with a more source dependence due to the direct land-based input. BC/TOC% values and the varied BC components (char and soot), as well as their correlations suggested that char was the predominant constituents of sedimentary BC both in the upper and lower Gulf, which could be mainly derived from biomass burning and entered into the nearshore region through direct fluvial transport and surface run-off. The estimated BC burial flux (~212 mg/cm 2 /y) and mass inventory (~200 Gg/y) in the GOT on the hundred-year timescale were of the same order of magnitude compared with other oceanic margins, and thus the tropical shelf sediments from SE Asia could serve as an important sink of land-emitted BC.

“…It has been increasingly applied to the characterization of organic matter (OM) in soils (Di Giovanni et al, 2000;Disnar et al, 2003;Hetényi et al, 2005;Sebag et al, 2006;Graz et al, 2012;Saenger et al, 2013;Hétényi and Nyilas, 2014), the detection of black carbon (Copard et al, 2006;Poot et al, 2009) and even the analysis of pure organic products (Carrie et al, 2012). It has also been applied for several decades to the study of recent lacustrine sediments (Campy et al, 1994;Di Giovanni et al, 1998;Meyers and Lallier-Vergès, 1999;Ariztegui et al, 2001;Steinmann et al, 2003;Sanei et al, 2005;Jacob et al, 2004;Boussafir et al, 2012;Zocatelli et al, 2012;Lavrieux et al, 2013;Sebag et al, 2013, amongst others) or recent marine sediments (Peters and Simoneit, 1982;Hussain and Warren, 1991;Calvert et al, 1992;Combourieu et al, 1999;Ganeshram et al, 1999;Ozcelik and Altunsoy, 2000;Holtvoeth et al, 2001Holtvoeth et al, , 2003Holtvoeth et al, , 2005Tamburini et al, 2003;Baudin et al, 2007Baudin et al, , 2010Kim et al, 2007;Marchand et al, 2008;Tribovillard et al, 2008Tribovillard et al, , 2009Biscara et al, 2011;…”

“…BC is a product of incomplete combustion of both fossil and contemporary (biomass) fuels, arising from combustion residues (e.g., charcoal) and condensed carbonaceous products [7] [8]. The continuum of properties from char and charcoal to soot particles does not have clear-cut boundaries [9], but the entire class of material is recognized to have large impacts on the global atmospheric carbon cycle and also provides a record of fire history [2] [7] [10]- [12]. Due to its inertness and thermal stability [5], BC transfers carbon from the rapid atmosphere-biosphere cycle into a much slower geological cycle.…”

We evaluate the applicability of an optical transmission measurement method commonly used for the analysis of the Black Carbon (BC) content of aerosol sample, to determine the BC content of loess sediments. A number of different sample pretreatment procedures are developed and compared, leading to an optimum preparation process. The results include: 1) Subtraction of the optical attenuation values before and after heating of the sample filters ("ΔATN") varies linearly with the sample mass. The slope of the regression line provides the best determination of BC concentration. 2) When the sample mass is small, (NaPO3)6 pretreatment is best for BC measurement, and the BC concentration results are given by the slope of the regression between ΔATN and sample mass, for a series of samples of varying mass. 3) HF pretreatment accompanied by centrifugation and rinsing may produce a negative bias on the result. 4) Replicate measurements of BC for loess samples showed a maximum deviation less than 5.6%, suggesting that measurements of the BC concentration of a sequence of loess samples could determine variations to this degree of significance. 5) The overall trends of BC concentration in loess section sequences were similar for all chemical pretreatments. The BC concentration result for replicate samples is comparable when pretreated by the same procedure.
