Laser induced breakdown spectrometry (LIBS) is a simultaneous multi elemental methods that enables a direct and fast analysis (0.5 min) of solid, liquid and gaseous samples; it shows a microanalytical capability since allows analysis of a very low sample mass size (<100ug) and for this reason is a quasi-nondestructive method; it allows an on-site and remote analysis since portable instrum…
Considering the refractory characteristic of high silicon content samples, such as rocks and slags that require use of different acid mixtures, high pressure and temperature to reach quantitative dissolution, the possibility of performing direct analysis seems to be a good alternative. Laser induced breakdown spectrometry (LIBS) has become an attractive and much explored technique in chem…

Brazil has 98.8% of niobium and 33.7% of tantalum reserves, holding a prominent position in the global market for these elements. Extraction occurs from columbite and tantalite minerals and the economically viable mines are often found associated with cassiterite (Sn content ore) in the northern Brazil, including states of Amazonas and Rondônia. These ores also contain rare earth elements…
The growing demand for new energy sources, including lithium batteries, has led to the beginning of a new era of exploration of sources of this element, the largest being brines and pegmatites. Among minerals, spodumene stands out for being the only one with an economically viable extraction route. Currently, around 70% of the world's lithium reserves are found in brines, located mainly b…
The remarkable worldwide production of nanomaterials and applications in different areas for biological and industrial purposes raises important environmental and public health issues. Thus, the inevitable increasing disposal of nanoparticles, such as silver (AgNPs) and gold nanoparticles (AuNPs), significantly increases the release of these compounds into the environment. In this scenari…
Laser-Induced Breakdown Spectroscopy (LIBS) has become a very attractive and widely explored technique in analytical chemistry. Despite the advantages, quantitative analysis is not an easy task, and has been considered the "Achilles' heel" of the technique. This fact is duet to the complex nature of laser-sample interaction which causes strong matrix interference. One way of minimizing th…
Laser induced breakdown spectroscopy (LIBS) has been an attractive and fairly explored analytical technique for elemental analysis of environmental, agronomic, and industrial samples with minimal or no sample preparation. Besides of characteristics of the direct analysis techniques, LIBS is multielement and can be used in field analyzes due to availability of portable instruments. However…

Increasing global production and application of nanomaterials for biological and industrial purposes escalate their release into the environment, raising ecological and public health concerns. Nanomaterial such as silver and gold nanoparticles, present in the growth medium, are potentially taken up by plant roots and then translocated to edible parts. In this way, nanomaterial may enter t…
