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 long- 
range 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
