Investigation of heavy metals accumulation in sediment and aquatic organism in Khodaafarin Dam, Azarbaijan-Sharghi, Iran

Heavy metals occur in the environment special aquatic ecosystems. They may be enter in food chain and can affect human and animals health. In this study concentrations of heavy metlas, such as Cd, As and Cu were determined in sediment, common reed (Phragmites australis) and the muscle fish (Abramis bram, Varicorhinus dapoeta, Capoeta capoet, Cyprinus carpio) using drying ash method and inductively coupled plasma-optical emission spectrometer (ICP-OES) instrument. ANOVA analysis showed significant difference between metal concentrations between samples (P 0.05). Concentrations of As and Cd in sediment and fish is above of standard guideline (EPA and FAO). Common reed accumulated execs of heavy metals.
