Arsenic (As), copper (Cu), nickel (Ni), zinc (Zn), manganese (Mn), lead (Pb), iron (Fe), aluminum (Al), cadmium (Cd) and chromium (Cr) accumulations were evaluated in the gills, hepatopancreas, exoskeleton, and muscles of Pontastacus leptodactylus (crayfish) (Eschscholtz, 1823). The highest metal accumulation was observed in the gills and hepatopancreas. It was detected a negative correlation between Cr-Pb, As-Cr in the muscle tissue. All other metals were displayed positive correlations with each other in the gills, hepatopancreas, and exoskeleton. Strong positive correlations were determined between Ni-Cd and As-Pb in the gills, Ni-Cd, As-Pb and Al-Zn in the hepatopancreas, Zn-Mn and Fe-Cu in the exoskeleton, Ni-Cd, As-Pb, Zn-Mn, Al-Mn, Fe-Cu and Al-Zn in the muscle (r= 1.000). PCA and cluster analysis generally were supported the correlations observed. The correlations between divalent metals may be expressed by the role of divalent metal transporter 1 (DMT1) in the gathering of these metals.
对细足绒螯蟹（小龙虾）（埃施霍茨，1823年）的鳃、肝胰腺、外骨骼和肌肉中的砷（As）、铜（Cu）、镍（Ni）、锌（Zn）、锰（Mn）、铅（Pb）、铁（Fe）、铝（Al）、镉（Cd）和铬（Cr）积累情况进行了评估。在鳃和肝胰腺中观察到最高的金属积累量。在肌肉组织中检测到铬与铅、砷与铬之间呈负相关。在鳃、肝胰腺和外骨骼中，所有其他金属之间均呈正相关。在鳃中，镍与镉、砷与铅之间呈强正相关；在肝胰腺中，镍与镉、砷与铅以及铝与锌之间呈强正相关；在外骨骼中，锌与锰、铁与铜之间呈强正相关；在肌肉中，镍与镉、砷与铅、锌与锰、铝与锰、铁与铜以及铝与锌之间呈强正相关（r = 1.000）。主成分分析和聚类分析总体上支持所观察到的相关性。二价金属之间的相关性可能由二价金属转运蛋白1（DMT1）在这些金属聚集过程中的作用来解释。
