Content: Our study established oil-specific (sub-)lethal effect concentrations for oil spill risk assessment. The oil types induced different strengths of embryo toxicity. Effects were not correlated with commonly measured PAHs. Sublethal exposure concentrations resulted in CYP1A induction, but no AChE inhibition was found. In contrast, zebrafish larvae showed strong behavioral impairment already at low exposure concentrations. Chemically dispersed oil caused higher toxicity than native oil, and the dispersant also seems to have directly contributed to this effect.
