Considering copper mine as main industrial unit of the area, Cu concentration in water and in sediments and Common reed roots have examined.
Vegetation of Aras river is comprised of Common reed, Tamarisk, Populus, Sedge distribute from terrestrial to riparian in suitable parts but Tamarisk and common reed is dominated in flooded, full of Potassium & Magnesium and having heavy metals respectively.
In past, extended common reed (Phragmites australis) strips supported huge pig (Sus scrofa) populations but Cu accumulation has decreased its density.
Common reed (Phragmites australis) is considered heavy metals bio-indicator with reference to this study so that it could be effective toward exclusion of throughout pollutants expansion.
Cu concentration, however, is more in sediment and common reed (Phragmites australis) than water.
