Tume, Pedro; Bech, Jaume; Tume, Luis; Bech, Joan; Reverter, Ferran; Longan, Lluis; Cendoya, Patricio (2008)Concentrations and distributions of six elements – Ba, Cr, Sr, V, Al, and Fe – in 29 Torrelles soil profiles (135 soil samples) were investigated. The soils were classified as Alfisols, Entisols, Inceptisols, Mollisols, ... -
Concentrations of heavy metals in urban soils of Talcahuano (Chile): a preliminary study
Tume, Pedro; Bech, Jaume; Sepúlveda, Bernardo; Tume, Luis; Bech, Joan (2008-05)Concentrations of Cd, Cr, Ni, Pb, and Zn in the top-(0–10 cm) and sub-surface (10–20 cm) soils of the Talcahuano urban area were measured. The main soil properties (organic matter, CaCO3, pH, particle sizes) were determined ... -
