Abstract

We have constructed a network system which enables one to access and analyze environmental data obtained at different and distant laboratories. As a preliminary feasibility test of the system, we studied the elements in the water of the Tesio River using PIXE and ion chromatography. Students used the data online to carry out analysis via internet. We found two factors with different features in calcium from the factor analysis. The comparison of the specific result and relevant geology information has revealed a remarkable presence of Ca²⁺ which might come from dissolution of limestone in the upper Tesio River. PIXE data gave crucial information to draw such a conclusion. The present system has been found useful in environmental education in universities, online sharing of PIXE data in particular.
