PCB accumulation and tissue distribution in cave salamander (Proteus anguinus anguinus, Amphibia, Urodela) in the polluted karstic hinterland of the Krupa River, Slovenia

► Proteus anguinus anguinus is neotene and troglobiont cave salamander. ► Concentration of PCB in its tissues from polluted area is extremely high. ► The PCB distribution in tissues is similar to distribution in other aquatic vertebrates exposed to PCB contamination. ► Proteus is capable of eliminating less chlorinated and mono-ortho PCB congeners.
