Laser-Induced Breakdown Spectroscopy for Rapid Discrimination of Heavy-Metal-Contaminated Seafood Tegillarca granosa

Abstract: Tegillarca granosa samples contaminated artificially by three kinds of toxic heavy metals including zinc (Zn), cadmium (Cd), and lead (Pb) were attempted to be distinguished using laser-induced breakdown spectroscopy (LIBS) technology and pattern recognition methods in this study. The measured spectra were firstly processed by a wavelet transform algorithm (WTA), then the generated characteristic information was subsequently expressed by an information gain algorithm (IGA). As a result, 30 variables obtained w… Show more

“…), compared to EDS (or EDX) technique [23,24]. Currently, owing to the rapid development of this technique, the use of LIBS is widespread in the theoretical and experimental research of many fields, such as those of mineral products, archaeology, biomedicine and aerospace exploration [25][26][27][28][29]. In particular, LIBS is currently the only feasible technique in fields that require remote elemental analysis [26].…”

In particular, LIBS is currently the only feasible technique in fields that require remote elemental analysis [26]. We have [30,31] evaluated the feasibility of using LIBS to achieve rapid, accurate, online monitoring of the ageing performance of silicone rubber and to determine the components (C, O, Fe and Si) that are closely related to the ageing state of silicone rubber.…”

“…There are numerous fields where LIBS analysers are used [ 12 ], such as basic scrap metal analysis [ 13 ], classification of alloys [ 14 ], or mapping of geological cores [ 15 ]. Additional uses include sophisticated applications such as adulteration detection in milk [ 16 ], discrimination of heavy-metal-contamination in seafood [ 17 ], analysis of pathological tissues [ 18 ], or precision agriculture [ 19 ]. They are even used with the most demanding space missions [ 20 ] and biohazard detection [ 21 ].…”
