Metals in the hydrological cycle represent a very broad subject covering
all parts of the geological cycle. The present version of this book,
therefore, would not have been possible without the comments and
suggestions for improvement on draft ver- sions of the various chapters
by a large number of colleagues. We wish to express our gratitude to:
P.A. Cawse (AERE, UK), J.N. Galloway (University of Virginia, USA) and
S.E. Lindberg (Oak Ridge National Labo- ratory, USA) for reviewing the
chapter on atmospheric trace metals. G. Batley (CSIRO, Australia) and
B.T. Hart (Chisholm In- stitute of Technology, Australia) for reviewing
the chapter on speciation of dissolved metals. E.K. Duursma (Delta
Institute, The Netherlands), J.M. Bewers and P.H. Yeats (Bedford
Institute of Oceanography, Canada) and D. Eisma (Netherlands Institute
for Sea Re- search, the Netherlands) for reviewing the chapter on
estuaries. P. Baccini (EAWAG, Switzerland) and W. Davison (Fresh- water
Biological Association, UK) for reviewing the chapter on lakes. E.T.
Degens (University of Hamburg, W-Germany) for re- viewing the chapter on
the oceans, and J.P. Al (Public Works Department, The Netherlands) for
reviewing most of the indi- vidual chapters. Without the collaboration
of these colleagues this book would not have been possible in its
present form.
