Polycyclic aromatic hydrocarbons (PAHs) were analyzed in oysters collected from 18 stations in the Yatsushiro Sea, western Japan. PAHs were detected in all samples analyzed, and the highest concentration (mean 230 ng/g wet weight) was found in oyster

The movements of the water masses are evaluated by Ra-228/Ra-226 (radioisotope ratio) in the open sea. However, the study on the water's movement in the littoral region based on this ratio is few, because the supply process of Ra-228 is complex. The
