Are metal-induced hypersensitivities in harbor seals associated with liver function?

► Influence of metal pollutants on the health of marine mammals. ► Chronic metal exposure induces hypersensitivities in harbor seals of the North Sea. ► Comparison of hematological and biochemical parameters of seals with and without hypersensitivities. ► Altered hematological parameters and liver enzyme patterns in seals with hypersensitivity.
