LOCAL ANALYSIS OF STRONTIUM USING FISH SCALE BY MICRO-PIXE WITH A CdTe X-RAY DETECTOR

Abstract

Sr is an indicator used in studies on fish migration. In this study, the Sr profiles of ridges, which are growth lines in fish scales, in Sakhalin taimen (Hucho perryi) were examined by micro-PIXE analysis. Sakhalin taimen were reared under freshwater conditions for six months. The ridges that formed during the rearing experiment were subjected to PIXE spot analysis. This analysis was performed in a 5 × 5 µm 2 area in the center region of each ridge of the scale section, and the Sr levels were calculated using the thin-section standard. The mean Sr concentration in the ridges was 428 ± 48 µg/g. The quantitative PIXE spot analysis successfully provided Sr profiles for the scale corresponding to ridge formation.

“…The ridges are sh growth lines in the scale, called sh scale ridges. 17 Two kinds of ridges are observed in the picture, narrow intervals and wide ones. In the narrow area, there is a crack which may have emerged during the drying process.…”
