Results of non target screening of lipophilic organic pollutants in the German Bight. IV: Identification and quantification of chloronitrobenzenes and dichloronitrobenzenes

Within this study all three monochloronitrobenzenes were identified and quantified in water of the German Bight of the North Sea. The concentrations ranged from <0.02 to 8.9 ng/L. The latter high value was found in the estuary of the River Elbe, though. Additionally, 2,5-dichloronitrobenzene and 3,4-dichloronitrobenzene were identified and quantified. The concentrations of these compounds ranged from <0.05 to 7.7 ng/L. The major path of input for the chloronitrobenzenes to this marine area is the River Elbe. A method for quantification is described.
