| Popis: | Measurements using atomic absorption spectrometry have established the prescence of Pb, Hg, Cd, Zn, Cu, and Cr in shells of the oyster Crassostrea virginica in amounts considerably higher than their concentration in sea water. Preliminary comparisons of trace elements in shells from widely separated areas do not suggest large differences. The relatively high values obtained for Pb, Cu, and Cd suggest these analyses have a good potential for assessment of man's contribution to global pollution. Comparison of these data with trace element content of ancient shells may be useful in evaluating the importance of pollution induced changes in coastal waters. |
