“…The use of internal standard calibration in LIBS is a good alternative to minimizing the standard deviation of the results, caused especially by the variations of the laser energy and by the heterogeneity in the density of material [13], which changes the amount of ablated material and consequently the precision of the results. The use of C as an internal standard in wood analysis by LIBS was previously proposed by Gething et al [13] and Uhl et al [14], who used calibration by the increase of spiking concentration of Al, As, B, Cd, Cr, Cu, Hg, K, Mg, Na, Pb, Si and Sn in wood samples. According to Uhl et al [13], C is present in wood matrix in a high mass fraction (approximately 50%) and the variation between different types of wood is not significant.…”

a b s t r a c tThe calibration and quantitative measurement is the ''Achilles heel'' of the LIBS technique. This paper deals with a method developed for the direct measurement of K and Mg in plant samples. Instrumental parameters were optimized and the best condition found was a 50 lm spot size, 10 Hz laser repetition rate, 75 accumulated laser pulses with 25 mJ/pulse and 0.25 ls of delay time. For method calibration, the use of synthetic standard calibrating material prepared by the addition of increasing concentrations of K and Mg in wood, filter paper and babassu mesocarp was proposed in order to assess the feasibility of using these various matrices in plant samples analysis. The limits of detection of proposed method were 2-30 and 6-27 lg g À1 for K and Mg, respectively. The use of the carbon emission wavelength at 247.856 nm was used as internal standard to improve the analytical results. Certified reference materials of plants were used to check the accuracy of the proposed method and recovery around 82% and 100% were obtained in all cases. Ó 2015 Published by Elsevier B.V.

“…Another application that is of great interest to plant and forestry scientists is the chemistry of wood response to precipitation and forest fires that occur naturally in the environment or controlled fire events. The housing industry is very much interested in sorting preservative treated wood [21,[60][61][62]. The authors have shown that LIBS has practical applications in recycling facilities and on building sites.…”

This chapter details the application of LIBS in a number of environmental areas of research such as carbon sequestration and climate change. LIBS has also been shown to be useful in other high resolution environmental applications for example, elemental mapping and detection of metals in plant materials. LIBS has also been used in phytoremediation applications. Other biological research involves a detailed understanding of wood chemistry response to precipitation variations and also to forest fires. A cross-section of Mountain pine (pinceae Pinus pungen Lamb.) was scanned using a translational stage to determine the differences in the chemical features both before and after a fire event. Consequently, by monitoring the elemental composition pattern of a tree and by looking for abrupt changes, one can reconstruct the disturbance history of a tree and a forest. Lastly we have shown that multivariate analysis of the LIBS data is necessary to standardize the analysis and correlate to other standard laboratory techniques. LIBS along with multivariate statistical analysis makes it a very powerful technology that can be transferred from laboratory to field applications with ease.
