摘要	This study focuses on copper (Cu) and zinc (Zn), the two heavy metals with the largest polluted areas in Taiwan’s soil, as the primary research subjects. The aim is to develop and assess the feasibility of applying multiple metal isotopes (Cu-Zn-Pb) for source identification of soil pollution. To achieve the research goals of this study, we have established a new high-precision isotopic technique, which has been successfully applied to the international soil standards and real samples. The tasks completed for this year’s project are as follows: (1) We have collected and compiled domestic and international literature and technical reports regarding the application of the Cu-Zn-Pb isotopes in polluted soils as tracers for source identification, which serves as a fundation for method development and the future applications. (2) Using a new generation high-resolution MCICP- MS, we have developed and refined a novel protocol, including sample preparation, chemical purification and isotopic analyses, for a variety of environmental materials. The analytical precision of the Zn isotope analysis has successfully impoved (±0.05‰, 2 s.d., for 20 ng of Zn) by using double-spike (67Zn-70Zn) technique and a desolvation system. The sample requirement for Cu can be significantly reduced to 10 ng while maintaining the analytical precision of ±0.06‰ (2 s.d.). (3) Sediments and soils collected from Taoyuan and Changhua pollution sites were selected to conduct sequential extraction experiments and the Cu isotope analysis, and the combined results suggested that the sources of Cu in Taoyuan and Changhua soils with the heaviest Cu isotope ratios were most likely related to water bodies in the farmlands. For the Miaoli site, the measured data indicate that the coupled Cu and Pb isotope tracing method can accurately identify three main sources of copper pollution at the site: factory wastewater, wastewater from cleaning tanks, and natural sources. (4) Two training courses covered sample preparation, sequential extraction, Cu-Zn-Pb purifications, isotopic measurements, as well as case studies were completed on July 5, 2024 and October 17, 2024.

This study focuses on copper (Cu) and zinc (Zn), the two heavy metals with the largest polluted areas in Taiwan’s soil, as the primary research subjects. The aim is to develop and assess the feasibility of applying multiple metal isotopes (Cu-Zn-Pb) for source identification of soil pollution. To achieve the research goals of this study, we have established a new high-precision isotopic technique, which has been successfully applied to the international soil standards and real samples. The tasks completed for this year’s project are as follows: (1) We have collected and compiled domestic and international literature and technical reports regarding the application of the Cu-Zn-Pb isotopes in polluted soils as tracers for source identification, which serves as a fundation for method development and the future applications. (2) Using a new generation high-resolution MCICP- MS, we have developed and refined a novel protocol, including sample preparation, chemical purification and isotopic analyses, for a variety of environmental materials. The analytical precision of the Zn isotope analysis has successfully impoved (±0.05‰, 2 s.d., for 20 ng of Zn) by using double-spike (67Zn-70Zn) technique and a desolvation system. The sample requirement for Cu can be significantly reduced to 10 ng while maintaining the analytical precision of ±0.06‰ (2 s.d.). (3) Sediments and soils collected from Taoyuan and Changhua pollution sites were selected to conduct sequential extraction experiments and the Cu isotope analysis, and the combined results suggested that the sources of Cu in Taoyuan and Changhua soils with the heaviest Cu isotope ratios were most likely related to water bodies in the farmlands.
