Q10 values calculated from maximum oxygen consumption rates (rmax) and lag times (tlag) at 0.5 and 5.0 °C (T(Q10)) for crude oil (Oil) and sodium-benzoate (Na-benzoate) from the first exposure. Error bars show the range between minimum and maximum values of Q10. Dotted = oil rmax, darker grey = sodium-benzoate rmax, dashed = oil tlag and lighter grey = sodium-benzoate tlag.
