The strongest correlations were observed between Mn-Cu (r=0.780) and Fe-Cu (r=0.744) in the hepatopancreas. The highest metal concentration was observed in hepatopancreas, the lowest was determined in the muscle tissue. Sequence of metal concentration levels were Al> Fe> Mn> Zn> Cu> Ni> Pb> Cr in exoskeleton and gills, Al> Fe> Mn> Cu> Zn> Ni> Pb> Cr in hepatopancreas and Al> Mn> Fe> Zn> Cu> Pb> Ni=Cr in muscle.enAstacus leptodactyluscorrelation analysismetal-metal interactionsArticle281
