Abstract
The main aim of this project was to provide a basis for assessing the potential health effects of produced water (PW) on the marine pelagic zooplankton Calanus finmarchicus in the field. This report describes three experiments assessing the impact of reconstituted PW extracts on copepod PAH body residue, stress gene expression and metabolic profiles. The project established relationships between produced water exposure, PAH uptake and biological responses in a laboratory settings, in order to be used as a basis for sampling and analyses of copepods exposed to environmentally realistic scenarios in the field. A selection of endpoints are suggested for analyses of field-collected copepods in the water column monitoring in 2017.
