Dredge Disposal Study San Francisco Bay and Estuary. Appendix F. Crystalline Matrix Study.

Abstract

A study was undertaken to determine the quantity and nature of certain heavy metals (Cd, Cu, Hg, Pb, Zn) that may be released from selected San Francisco Bay sediments as a function of various physical and chemical parameters. Ten sediment sampling stations in San Francisco Bay were selected to represent the range of sediment types and heavy metal concentrations which are involved in routine maintenance dredging and disposal. For three regions a semi-selective chemical extraction procedure was utilized to determine the relative distribution of the heavy metals among the various geochemical phases. The greatest portions of heavy metals were found bound in clay or crystalline lattice-like and organic or sulfide-like sites.
