Abstract

ABSTRACT. This study aims to determine and compare the heavy metal concentrations in the water, sediment, and plants of the Karasu river in Erzurum, Türkiye. In this context, aluminum (Al), manganese (Mn), iron (Fe), nickel (Ni), zinc (Zn), and barium (Ba) concentrations were measured for this study. Salix excelsa (willow), Rosa canina L., Pyrus elaeagnifolia (wild pear), Malus sylvestris (wild apple), and Hippophae rhamnoides L. (sea buckthorn) plants were used as samples. Heavy metal concentrations follow the order of Al3+ > Fe2+ > Mn2+ > Ba2+ > Ni2+ > Zn2+ in the sediment. Heavy metal concentrations follow the order of Al3+ > Fe2+ > Ba2+ > Mn2+ > Zn2+ > Ni2+ in water. The leaf part of Salix excelsa has the highest bioconcentration factor (BCF) for Mn among plant parts. Mean BCF values were as follows: Zn2+ > Mn2+ > Ba2+ > Ni2+ > Al3+ ≈ Fe2+. In addition, the highest plant translocation factor (PTF) values were determined in Salix excelsa for Al and Fe; in Rosa canina L. for Ni and Zn; in Hippophae rhamnoides L. for Mn and in Malus sylvestris for Ba.
