誘導結合プラズマ質量分析法を用いた環境水中微量有害金属元素分析

Abstract

To clarify the influence of unlawfully dumped wastes in the boundary area between Aomori and Iwate prefecture,we are analyzing the trace and toxic metal elements in leached water from the field and collected water samples around the field by using inductively coupled plasma spectrometry. We collected water samples from eleven points and confirmed that the concentrations of cadmium,lead and mercury indicate below the environmental standard values. But the obtained values for arsenic and selenium in some of the samples showed the higher values affected by the coexistence materials. We therefore measured these concentrations of the two elements by another method of atomic absorption analysis and clarified that each concentration for arsenic and selenium is also lower than the environmental standard for each element
