Abstract
Cultures of the marine diatom, Nitzschia liebethrutti were maintained in 1.5 μg-at/L of either inorganic Hg or Sn ions. Electron micrographs of cleaned frustules from these cultures were analyzed for frustule abnormalities. Abnormalities were significantly greater in diatoms grown with Hg and Sn ions than in controls. Frustule abnormalities common to both Hg and Sn were reduction in length/width, fused carinal dots and reduction in the number of carinal dots/frustule. Curved raphes and carinal dots aligned parallel to the raphe appeared only in frustules from Sn treatment.
