“…Given the importance of knowing the behavior of different types of soil when affected by fire, a significant number of scientific studies have been made by analyzing, in field or laboratory, these structural changes (Certini 2005;González-Pelayo et al 2006;Arcenegui et al 2010;Salgado et al 2004;Carrington 2010;Esque et al 2010;Santin et al 2008;Ferreira et al 2008;Notario del Pino et al 2007). …”

“…The use of near-infrared spectroscopy (NIRS) analytical techniques has gained, in recent years, increasing importance in widely different areas of knowledge, namely, medical and biomedical, − pharmaceutical, − food, − biofuels, − and forestry. − These techniques are popular because they allow the development of new methodologies that simplify analysis and provide accurate and precise results in agreement with those obtained by the usual traditional methods. Also, when needed, the pretreatment of the sample is minimal, although in most of the situations the samples do not need pretreatment at all.…”

Near-infrared spectroscopy (NIRS) in conjunction with multivariate calibration have proved to be adequate techniques to predict water content as well as methanol concentration in a industrial multicomponent mixture. The calibration models were developed using real industrial complex samples of water, methanol, and several other components in variable but lower concentrations such as sulfonic acids, acetone, and methyl cyanide. These samples come from industrial distillation of hydrated methanol. Prior to the establishment of the two calibration models, wavelength selection, original spectral data compression by means of the principal components analysis technique, and preprocessing optimization were performed. Calibration was modeled according to partial least squares (PLS) regression which was developed using the mean centering and the leave-one-out cross validation (LOOCV) method for the optimization of the principal components (PC) number. Both models were developed in the 5369−5153 cm −1 spectral region. Karl Fischer titration and gas chromatography were used as reference methods for water and methanol quantification, respectively. The suitability of the models was evaluated through the calculation of the standard error of calibration and standard error of prediction. For the water content determination the variance scaling pretreatment was applied with 12 PLS factors, the calibration and prediction errors being 2.56% and 1.76% respectively. As for the methanol concentration variance scaling was applied in conjunction with Savitzky−Golay's second order derivative with six PLS factors. In this case the calibration and prediction errors were 0.42% and 0.90%, respectively.

“…The effects of fire on slash‐and‐burn agriculture, as well as socioeconomic impacts, are reported in different ecosystems of the tropics (Are et al, 2009; van Vliet et al, 2012; Thomaz, 2013; Ngo‐Mbogba et al, 2015). In addition to fire caused intentionally by humans, wildfire is another event responsible for severe disturbance in many ecosystems (Shakesby and Doerr, 2006; Arcenegui et al, 2010; Vega et al, 2013; Yusiharni and Gilkes, 2012). An important aspect in evaluating fire effects is to assess the soil burn severity (Shakesby and Doerr, 2006; Mataix‐Solera et al, 2011; Bento‐Gonçalves et al, 2012; Vega et al, 2013; Moody et al, 2013).…”

“…In the last years, given the advances in analytical instrumentation and in computational data evaluation, spectroscopy techniques present an alternative for determining several parameters. For instance, a recent study involving nuclear magnetic resonance for 13 C analysis aided in the interpretation of organic matter thermal properties (Merino et al, 2014) and the use of near‐infrared reflectance (NIR) spectroscopy to estimate the maximum reached temperature in fire affected soil (Guerrero et al, 2007; Arcenegui et al, 2010) and the presence of ash in burned areas (Arcenegui et al, 2008). Moreover, thermal analysis is increasingly being used (Neris et al, 2014; Merino et al, 2015).…”

An important aspect for the evaluation of fire effects in slash-and-burn agricultural system, as well as in wildfire, is the soil burn severity. The objective of this study is to estimate the maximum temperature reached in real soil burn events using energy dispersive X-ray fluorescence (EDXRF) as an analytical tool, combined with partial least square (PLS) regression. Muffle-heated soil samples were used for PLS regression model calibration and two real slash-and-burn soils were tested as external samples in the model. It was possible to associate EDXRF spectra alterations to the maximum temperature reached in the heat affected soils with about 17% relative standard deviation. The results are promising since the analysis is fast, nondestructive, and conducted after the burn event, although local calibration for each type of burned soil is necessary.
