Various foods including farm products, fishes and dairy products collected in the contaminated areas in Bangladesh and Mongolia have been analyzed. As a result, it becomes possible to evaluate the actual condition of contamination, to presume the pathways of exposure and to estimate total intakes of toxic elements for the people considering their eating habits. Also, a two-detector measurement system, consisting of two Si(Li) detectors with a vacuum cap and an X-ray absorbers, has been established in in-air PIXE system, and the method of quantitative analysis has been developed. Furthermore, the new method of quantitative analysis of living plants has been developed, and it became possible to observe movement of certain toxic elements in living plants.

在孟加拉国和蒙古的污染地区收集的各种食品，包括农产品，鱼类和乳制品进行了分析。因此，可以评估污染的实际情况，推测接触途径，并根据人们的饮食习惯估计有毒元素的总摄入量。在空气中建立了由两个Si（Li）探测器和一个X射线吸收器组成的PIXE双探测器测量系统，并建立了定量分析方法。此外，还开发了活体植物定量分析的新方法，使观察活体植物中某些有毒元素的运动成为可能。
