dc.description.abstractTwo performance fluids were tested for toxic effects on marine algae and biological degradability. A fluid based on mineral oil was readily degradable (98% DOC removal in 28 days) while a either based oil degraded more slowly (56 % DOC removal in 28 days). The toxicity of both fluids was tested after emulsification of the oils in water and separating the oil and water phase after equilibration. The EC50 values obtained with this approach were 8.15 g/l for the oil based fluid and 116 g/l for the ether fluid.nb_NO
