“…ATR is applied for the investigation of SOM (Artz, et al, 2008;Cecillon, et al, 2012;Delarue, et al, 2013;Gezic, et al, 2012;Li, et al, 2010;Neves-Fernandes, et al, 2010;Tremblay, et al, 2011;Vergnoux, et al, 2011) or when ions, like nitrate, ammonium etc., are assayed in soil (Du and Zhou, 2009;Jahn, et al, 2006). This technique ensures a direct analysis of undiluted opaque samples in a highly reproducible way (Tremblay, et al, 2011), permitting band intensities to remain within a linear range.…”

“…Depending on fire severity, the effects on the OM consist in slight distillation, charring, or complete oxidation. The fire effects, both in situ and in laboratory, led to an enrichment in aromaticity and a decrease in O-containing functional groups Knicker, et al, 2005;Nocentini, et al, 2010;Vergnoux, et al, 2011). Although the identification of charcoal in soil is difficult, there is now evidence for the presence of charred material in soils thought FTIR spectroscopy Nocentini, et al, 2010;Vergnoux, et al, 2011).…”

“…KBr-pellet), DRIFT or ATR, depends on parameters such as the sample size, the information needed (bulk versus surface analysis) or the time required for the sample preparation. Currently, the improved design of DRIFT accessories has made this technique widely used for studying soil compounds (Aguiar, et al, 2013;Calderon, et al, 2011aCalderon, et al, , 2011bDemyan, et al, 2012;Ellerbrock, et al, 2009;Francioso, et al, 2009;Leue, et al, 2010;Ludwig, et al, 2008;Minasny, et al, 2008); ATR is also now being widely used (Artz, et al, 2008;Gezic, et al, 2012;Neves-Fernandes, et al, 2010;Vergnoux, et al, 2011).…”

The present review highlights the recent applications of mid-infrared spectroscopy and in particular of diffuse reflectance spectroscopy (DRIFT) and attenuated total reflectance (ATR) and processing methods (e.g., deconvolution, derivative and chemometrics) to rapidly provide valuable information on soil composition and organic geochemistry. Research has demonstrated that both DRIFT and ATR techniques can be considered useful tools for the analysis of a large number of soil samples, giving not only typical spectral patterns but permitting an accurate prediction of quantitative parameters such as, e.g., total carbon, total nitrogen, C/N ratio, lignin, dissolved OC, carbonyl-C, aromatic-C, O-alkyl-C, and alkyl-C contents. Based on literature results, infrared spectroscopy can be recognized as one of the most promising analytical techniques for investigating soil science.

“…The content and quality of HS strongly influence the total and labile trace elements content in the soil (Karabcová et al 2015) that can play the role of possible glue agents. HS are one of the most important fractions of SOM (Vergnoux et al 2011), which may also through its functional groups enter into interactions with metal ions to form complexes. In terms of a long term stability of soil aggregates, their humified and hydrophobic components are mainly important (Sodhi et al 2009).…”

Tobiašová E., Barančíková G., Gömöryová E., Dębska B., Banach-Szott M. (2018): Humus substances and soil aggregates in the soils with different texture. Soil & Water Res., 13: 44−50.Humus substances (HS) influence the incorporation of carbon into soil aggregates in many ways. In this study the influence of HS and their fractions in the soil on the proportions of carbon (total organic, labile, non-labile) in water-resistant macro-aggregates (WSA) and differences between the amount of carbon in WSA in coarsegrained (CGS) and fine-grained (FGS) soils with dependence on the proportions of HS in the soil were determined. The experiment included three soils (Haplic Chernozem, Haplic Luvisol, Eutric Cambisol), each of them with two different soil textures (CGS, FGS) from four ecosystems (forest, meadow, urban, and agro-ecosystem). In CGS, higher proportions (52 and 50%) of smaller (< 1 mm) dry-sieved macro-aggregates (DSA) and also WSA were determined, while in FGS, higher proportions (51 and 53%) of larger DSA (> 7 mm) and WSA (> 2 mm) were detected. A negative correlation was recorded between the content of organic carbon in the fractions of WSA and the amount of extracted humic acids (HA) in CGS, and fulvic acids (FA) in FGS. In CGS, the correlation between the carbon content in WSA and HA bound with Ca 2+ and Mg 2+ , which forms humates (HA2), was negative. In FGS, a negative correlation was recorded between the carbon content in WSA and free aggressive FA (FA1a) and free FA and those, which are bound with monovalent cations and mobile R 2 O 3 (FA1) in the soil. In the case of FA1a, a negative correlation was recorded in FGS and also in CGS, however this influence was more marked in CGS than in FGS (by about 21% higher correlation). In CGS, the influence of HA and FA in soil on the content of labile carbon in aggregates was stronger than in FGS. In CGS, a higher proportion of carbon in aggregates was detected in the case of lower stability of HS and HA and, on the contrary, in FGS, a higher content of carbon in aggregates was detected in the case of their higher stability.

Analysis of aerosol composition data for western United States wildfires between 2005 and 2015: Dust emissions, chloride depletion, and most enhanced aerosol constituents

This study examines major wildfires in the western United States between 2005 and 2015 to determine which species exhibit the highest percent change in mass concentration on day of peak fire influence relative to preceding nonfire days. Forty‐one fires were examined using the Environmental Protection Agency (EPA) Interagency Monitoring of Protected Visual Environments (IMPROVE) data set. Organic carbon (OC) and elemental carbon (EC) constituents exhibited the highest percent change increase. The sharpest enhancements were for the volatile (OC1) and semivolatile (OC2) OC fractions, suggestive of secondary organic aerosol formation during plume transport. Of the noncarbonaceous constituents, Cl, P, K, NO3−, and Zn levels exhibited the highest percent change. Dust was significantly enhanced in wildfire plumes, based on significant enhancements in fine soil components (i.e., Si, Ca, Al, Fe, and Ti) and PMcoarse (i.e., PM10–PM2.5). A case study emphasized how transport of wildfire plumes significantly impacted downwind states, with higher levels of fine soil and PMcoarse at the downwind state (Arizona) as compared to the source of the fires (California). A global model (Navy Aerosol Analysis and Prediction System, NAAPS) did not capture the dust influence over California or Arizona during this case event because it is not designed to resolve dust dynamics in fires, which motivates improved treatment of such processes. Significant chloride depletion was observed on the peak EC day for almost a half of the fires examined. Size‐resolved measurements during two specific fires at a coastal California site revealed significant chloride reductions for particle aerodynamic diameters between 1 and 10 μm.
