Abstract
    Concentrations of dissolved Cu, Zn and Mn have been recorded together with salinity, suspended particulate load, dissolved oxygen and pH, in twenty-two transects of the Tamar Estuary carried out between 1976 and 1985. The axial profiles of dissolved Mn accord with the results of previous studies. These showed persistent minima indicating varying degrees of removal within the low salinity, high turbidity region. The pattern of Zn distributions was similar to that of Mn. Removal of Zn occurred in the same low salinity region but was generally less accentuated. The mid-estuarine Zn maxima fell within the salinity range 3-20 ppt. Cu was also removed within the low salinity region but the mid-estuarine maxima were confined to the 1-8ppt salinity range.
