Two subjects offered in reply to a campaign for promotion of accelerator application are studied. One is quantitative analysis of boron content in the seabed mud, which might be related to triphenylboranepyridine (TPBP) currently used as antifouling agent. It is shown that nuclear reaction analysis (NRA) using 11B(p,3α) reaction is able to quantify B concentration of the order of ppm in highly pure carbon, and that the seabed mud in Fukae port contains B with a concentration of the order of 100 ppm, which is one order of magnitude greater than that in the earth crust. The other is elemental analysis of garlic to distinguish the place of its cultivation. Particle-induced-X-ray-emission (PIXE) analysis and 7Li(p,2α)-NRA are successfully applied to find that the garlic cultivated in China contains richer amount of Fe, Sr and Li than domestic one by a factor of 3.0, 2.4 and 94, respectively. It is concluded that the accelerator analyses could be widely applied in a variety of fields of environmental science and agriculture.
