Abstract

Trace elements in shells of short necked clams were analyzed with PIXE. Two groups of the shells ware sampled from high salinity and low salinity. Strontium (Sr) and Iron (Fe) concentration ware significantly different between the two groups. Although water temperature and salinity may affect Sr concentration in the shells, the Sr concentration was higher in better growth clams.
