Resumen:
The prediction about metals behaviour in soil requires knowledge on their solid?liquid partitioning.17 Usually it is expressed with an empirical distribution coefficient or Kd, which gives the ratio of the18 metal concentration in the solid phase to that in the solution. Kd values have been determined for Zn,19 Pb and Cd from samples representing the two most exploited aquifers in Argentina, Pampeano and20 Puelche, at three different locations in the province of Buenos Aires. The Pampeano aquifer presented21 higher Kd values than the Puelche aquifer. Comparing Kd values, different relationships could be22 observed: a) Pampeano aquifer: Pb > Zn> Cd, and b) Puelche aquifer: Pb > Cd > Zn.
