Trace elements are currently of environmental concern. They are harmful to humans, animals and tend to bioaccumulate into the food chain. In this study, the concentrations of trace elements in soil and sunflower plant parts have been investigated. The concentrations of copper, manganese, iron, zinc in soil and sunflower plant samples collected from 5 different locations in Corlu, Turkey were determined by flame atomic absorption spectrometry after wet ashing. The maximum concentrations of trace elements per kg soil were 6.37 mg Cu, 0.53 10(3) mg Mn, 1.05 10(3) Mg Fe, and 36.07 mg Zn. The orders of their concentrations in soils and plant parts were found to be Fe>Mn>Zn>Cu. The maximum metal concentrations, except for Fe concentration, were observed in the leaves and seeds of plant parts. In addition, the sunflower leaves collected at locations 4 and 5 were observed for phytotoxic Mn concentration.
