Brussels · Luxembourg, 1995 Foreword
One of the great unknowns in the current unplanned experiment of mankind on
stratospheric ozone depletion is the eventual impact of enhanced UV-B radiation on
health and the environment.
Good environmental policy requires a sound scientific basis and the European
Commission has been active at both policy andc levels in aiming to minimise
such impacts. Thus far, we have been remarkably successful in increasing our
understanding of the physical and chemical processes underlying ozone depletion and
now that we have a clearer idea of the possible extent of the damage it is time to
address the consequences ofthat damage.
I am confident that this, the First European Symposium on Environmental UV
Radiaiton will be effective in promoting the establishment of a strong European UV
research community not only through the sharing of ideas and information but also
through the development of new groups, new synergies, and new directions for
Community research. The European Commission will, wherever necessary, continue
to act in fostering research in this area in current and future programmes and I am sure
that the research priorities identified in the Symposium will be noted and acted upon in
the preparation of the new ENVIRONMENT and CLIMATE (1994-1998) research
programme of the Commission.
Finally, I wish to thank our hosts, the GSF Forschungszentrum für Umwelt und
Gesundheit, for their continued collaboration with the environmental research
programmes of the Commisison and I look forward to their active participation in the
future.
