Abstract
The NMR spectra were measured in solution, for a series of compounds m odelling the interaction of lead(II) with the humic substances of the soil. From the results it appears that the metal binding site is predo minantly the carboxylate group. The Pb-207 chemical shift is as a sens itive probe of the complexing ability of the various ligands and can b e used as an analitycal tool in the study of the interaction of this m etal with the soil organic matter.
