Uptake and Distribution of Different Copper Compound in Tissues of Crayfish (Astacus leptodactylus)

Abstract

This study was carried out to determine accumulation of different copper compounds (organic and inorganic) in various tissues and doses of crayfish (Astacus leptodactylus) during the period by the 7th, 14th and 21st days. The hepatopancreas exhibited the highest copper concentrations and the greatest copper accumulation in A. leptodactylus, followed by gill, muscle and carapace. After the 21st days of exposure, the maximum accumulations occurred in Copper (II) chloride dihydrate medium (90.84 and 106.81 mu g g(-1) wet wt.) which were followed by Copper (II) sulfate pentahydrate (86.46 and 101.50 mu g g(-1) wet wt.) and Copper (II) acetate monohydrate (78.90 and 92.00 mu g g(-1) wet wt.) at 8 and 12 mgl(-1) doses in the hepatopancreas. We suggest that copper limited levels and hazards are important parameters in determining where the structures of copper compounds are coming from.
