" ， 欄位Project Subject的內容是"This three-year project aimed at the development of LA-ICP-MS method in conjunction with X-ray fluorescence (XRF) and X-ray absorption spectroscopic (XAS) methods for determining the speciation and spatial distribution of heavy metals in soils and plants for understanding the key reactions and factors determining the chemical transformation and translocation of heavy metals in soils and plants. The abovementioned analytical techniques were developed to study the transportations of As, Cd, Cr, Cu, Hg, Ni, Pb and Zn in soils and plants and at soil/plant root interfaces in the first two years of this project and those of four emerging contaminants (i.e. Ga, In, Tl and Mo) in the third year. Ga, In, Tl and Mo were analyzed on soil and plant samples and certified materials. As shown in the results, the accuracy of LA-ICP-MS method is not sufficient for analysing the contents of Ga, In, Tl and Mo in soil and plant samples. Nonetheless, it provides a good precision of quantification for determining the spatial distributions of different metals in plant and soil samples. The accuracy and precision of quantification by LA-ICP-MS can be further improved by the internal standard method. In addition, vanillic acid could be employed as binder for soil sample to improve the analytical performance of the LA-ICP-MS method. Subsequently, the LA-ICP-MS method was applied to determine the spatial distributions of Ga, In, Tl and Mo in the thin sections of the grain and rhizophere samples of rice and wheat. In addition, micro-XRF and XAS methods were used to investigate the spatial distribution and speciation of heavy metals in soils and plants. The results indicated that the mobilities and availabilities of Tl and Mo in soils were higher than those of Ga and In. This study has developed the methodology of using LA-ICP-MS and synchrotron-based X-ray microprobe methods to determine the speciation and spatial distribution of metals within a heterogeneous sample, such as soils and plants, and at soil-plant root interfaces using. The information will advance our understanding of the key processes that determine the bioavailability of heavy metals in soils and their transformation within the plants after metals are absorbed by the plants.
