Many areas of Eastern Europe have been polluted to an extent unknown in
the West. Four such sites - Kola Peninsula, northern Bohemia, upper
Vistula Basin, and Katowice - have been identified and detailed accounts
of the pollution at these sites are given. The current status of the use
of biomarkers in hazard assessment is given by several scientists from
NATO countries. Four working groups, comprising scientists working on
the polluted sites and western scientists with expertise in biomarkers,
examine the use of biomarkers to assess the environmental health of each
of these areas and make recommendations on the future direction of
remedial action in these areas.
