Abstract The influence of NTA, EDTA, STPP, Triton X100, PO inf4 sup3 and NO inf3 sup− on the mobilization of Pb, Cd, Cu, Cr and Mn from sediments of two rivers located in Northern Greece was studied. The release caused by all examined complexing agents was higher in deionized water than either Axios or Aliakmon river water due to the lack of competition of Ca and Mg cations with the heavy metals for the studied complexing agents, and the decrease of ionic strength. From all examined agents NTA and EDTA showed the greater mobilization ability. Copper showed the greater tendency for remobilization by all examined agents, (according to the order: EDTA≅NTA, Triton X1004 PO inf4 sup3− 〉 NO inf3 sup3− ≅STPP) while Cr and Mn the smallest following the orders: NTA, PO inf4 sup3− 〉〉 NO inf3 sup− , Triton X1004 EDTA, STPP and STPP 〉 EDTA 〉 NTA 〉 Triton X 100 ≅ PO inf4 sup3− NO3, respectively. An increase in mobilization was noticed with an increase of agent concentration and time of shaking.
