Improvement  of  the  methodology  of  analysis
of  some  heavy  metals  which  are  routinely  determined ­
  in  seawater  and  marine  organisms.
Development  of  a  micro-procedure  to  be  able
to  determine  extremely  small  amounts  of
heavy  metals  and  bioavailable  heavy  metals
in  seawater  (speziation).

Determination  of  both  "former"  organohalogens
and  "new"  polar  organochemicals  in  a  screening
procedure.

The  automatic  system  is  a  supplement  to  existing
sample  taking  facilities  for  a  better  determination
of  organic  pollutants.

Examination  of  the  transport  of  dissolved  and
particle  -  bound  heavy  metals  and  radionuclides
through  the  biogeochemical  zones  within  the
sediment  as  well  as  through  the  sediment  -
water  boundary.
(Quantitative  estimation  of  the  intensity  of
remobilization  and  bio-availability  of  heavy
metals  from  the  sediments  as  a  consequence  of
seasonally  varying  biological  events  in  the
shallow  water  areas  of  the  German  Bight.)
