RT Journal Article T1 Aplicación de los isótopos estables del plomo al estudio de la contaminación de aguas subterráneas en un sector del acuífero Almonte-Marismas (Huelva) T1 Aplication of lead stable isotopes to groundwater contamination study on a sector ofthe Almonte-Marismas aquifer A1 Olías Álvarez, Manuel A1 Cerón García, Juan Carlos A1 Fernández, I. A1 Olivas, E. A1 Rosa Díaz, Jesús de la AB 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 PB Sociedad Geológica de España YR 2002 FD 2002 LK http://hdl.handle.net/10272/9093 UL http://hdl.handle.net/10272/9093 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 30 may 2026
