Llilfusion it, Environmental Pollution. Volumes IXA and 1XB are a sequel
to Volume 6: which contained the first symposium; though published
16 years ago. a number of these papers are still widely cited. Thcre is
little doubt that the contents of the present volumes contain equally outstanding conlrihutions. The organizers of the Symposium were singularly
successful in attracting a worldwide group or authorities in the field and
deberve for this the gratitude of the intcrcstcd scientific public. We also

Munn did an outstanding job for which the readers should give them full
credit.
A second reason why we arc particularly pleased to see these volumes
appear is the current nced to present all wailable knowledge in the field
in a world threatened by pollution. Admittedly we are still far from the

problems in the field. Yet there has been great progress in understanding
and not inconsidcrable success in use of whatever insight has been gained.
Moreover, iis these voluines show, there is a close alliance between pure
and applied science that has helped in the past and bodes well for the
future. I t is our hope. nay our conviction, that the papers in these volumes
will provide considcrablc stimulus for further research in an intriguing
