Laser Induced Breakdown Spectroscopy (LIBS) is an emerging analytical technique that allows the direct analysis of solid samples. The combination of total LIBS spectra profile and chemometric strategies can lead to analytical methods able to identify toxic elements in solid samples. This approach is intended to be applied for waste electrical and electronic equipments (WEEE) and cosmetic analysis. Old mobiles phones, personal computers accessories (mouse, keyboards, integrated circuits, among others) will be tested. During the experimental work, several spectra from different equipments will be recorded and the total peak profile will be applied to build classification models aiming the identification of fabricant and source. The goal is with the use of LIBS spectra and elements' concentration obtained by FAAS and ICP-MS to build calibration models using chemometric tools like PLS (Partial Least Squares). The proposed project can offer a current scenario of the WEEE and cosmetics commercialized in Brazil with potential impact to support recycling programs and critical information for public health.
