Rivers are the sensitive ecosystems due to their conditions. Determination of pollutant such as heavy metals in benthic samples is one of the most important indices for studying of rivers pollution. In this study, sampling of water, sediments and muscle of Crayfish, Astacus leptodactylus, was carried out in six stations of river. Then, the heavy metals chemical analysis of the samples was done by Atomic Absorption Spectrophotometer (A.A.S ). Mean rate of Cu, Pb, Cd, Cr, Zn, Ba and Fe in water of inspected stations was 6.95, 1.33, 2.62, 3.28, 124.2, 134.96 and 5.06 mg/lit, respectively, that aren’t suitable to drink (in the base of global standards), although this water can be used for agriculture and aquaculture. Also, heavy metals content in the sediments had been in the tolerance ranges for aquatic animals. Mean contents of heavy metals in muscle of Crayfish, Astacus leptodactylus, inspected stations are 45.73, 2.44, 3.27, 184.20, 145.12 and 9.66 for Cu, Pb, Cd, Cr, Zn, Ba and Fe respectively (mg/kg dry weight) that is less than range of sanitary standards for human consumes. There is significant correlation between heavy metals contents in water, sediments and Crayfish, Astacus leptodactylus in Abbasa river.
