Figure  46:  Trifluralin  concentrations  [pg/L]  in  surface  water  (5  m)  in  2003

In  2004,  some  samples  were  taken  in  the  Greenland  Sea  to  check  for  possible  longrange
  transports  and  investigate  background  concentrations.  No  trifluralin  above  the
LOD  was  detected  in  these  samples.
In  winter,  concentrations  in  the  German  Bight  were  an  order  of  magnitude  higher  than
in  summer,  and  were  in  the  range  from  100  to  580  pg/L  with  a  median  of  180  pg/L.  The
