The assessment of a no-effect concentration of oil in thermally treated OBM drill cuttings for marine benthos : sediment analysis and bioaccumulation
The no-effect concentration of thermally treated oil based mud (OBM) drill cuttings for marine benthos has been assessed in a 3 month mesocosm-scale bioassay with intact sediment-cores, including the natural infauna and stocked sea-potatoes (Echinocardium cordatum). This report describes the characterization of the thermally treated drill cuttings, the accumulation of oil and particles shorter than 63 um from this treated cuttings material in the sediment and the accumulation of oil in Echinocardium cordatum and mussels (Mytilus edulis) exposed to sediments dosed with this material and the overlying water respectively.
