Plastics are the most important materials used in a number of applications. Since the plastic has been synthesized commercially, the production, consumption and generation of plastic waste is still growing. Appropriate plastic waste treatments are very essential for both economically and environmentally. Because plastic material has a very high calorific value, it could play a roll as a alternative energy source instead of fossil fuels. As a necessary consequence, however, the combustion of plastic waste emits several hazardous air pollutants (HAPs). Therefore, the composition of plastic waste might be fundamental and preliminary information for evaluating their economic values, environmental impacts, and human health risks. LA-ICP-MS has been widely investigated as a powerful analytical technique for the direct analysis of solid matrix samples. The advantages are fast in-situ analysis, low sample consumption, and lack of polyatomic interference species. Moreover, LA does not require complicated sample-preparation procedures, so the risk of contamination or sample loss can be avoided. In this study, polyethylene (PE) materials were analyzed by LA-ICP-MS. We describe using the LA-ICP-MS equipment to explore the most optimal conditions for in-situ quantitative trace element analysis of plastic waste. The BCR-680 was used for the analytical QA/QC.
