  1. New insights into arsenic and cadmium distribution and origin in paddy soils using electrical resistivity tomography por Chaali, Nesrine, Bravo, Daniel, Ouazaa, Sofiane, Jaramillo Barrios, Camilo Ignacio, Beltran Medina, Jose Isidro, Serralde Ordoñez, Diana Paola, Benavides Erazo, Javier

    Publicado 2025
    “…In-situ geophysical techniques based on electrical resistivity tomography were performed to determine the spatial and temporal distribution of heavy metals. This paper aimed to pursue a novel methodology consisting in combining electrical resistivity tomography measurements, soil chemical data, and statistical analysis to predict As and Cd distribution in paddy soils. …”

  2. Tolerance and Cadmium (Cd) Immobilization by Native Bacteria Isolated in Cocoa Soils with Increased Metal Content por Feria Cáceres, Pedro F., Penagos Velez, Lucas, Moreno Herrera, Claudia X.

    Publicado 2025
    “…Twelve cadmium native bacteria previously isolated in soils of cocoa farms located in the western Colombian Andes (Santander), and tolerant to 2500 M CdCl2 (120 mg Cd/L), were chosen in order to test their tolerance and Cd immobilization using liquid culture medium (Nutritive broth) at different concentrations of heavy metals. Furthermore, in the greenhouse experiments, the strains Exiguobacterium sp. (11-4A), Klebsiella variicola sp. (18-4B), and Enterobacter sp. (29-4B) were applied in combined treatments using CCN51 cacao genotype seeds grown in soil with different concentrations of Cd. …”
