Aplicación de los isótopos estables del plomo al estudio de la contaminación de aguas subterráneas en un sector del acuífero Almonte-Marismas (Huelva)

Abstract

Results from a lead isotopic content research on a sector of the Almonte-Marismas aquifer are presented.

A strawberry irrigation farming has been introduced on the studied sector. The lowest value of isotopic rate 20SPb/206Pb and 206Pb/207Pb detected in a sampling point are interpreted as the natural isotopic content of the sector, that is to say unaffected by anthropogenic contamination. On the contrary, highest values may be associated to high contents of nitrates, lead, beryllium and other elements from the agriculture activities
