  • Evaluation of tests to assess the quality of mine-contaminated

    2008/02/02· An acid metal-contaminated soil from the Aljustrel mining area (a pyrite mine located in SW Portugal in the Iberian Pyrite Belt) was subjected to chemical characterisation and total metal quantification (Cd, Cr, Cu, Ni, Pb and Zn). Water-soluble metals were determined and a sequential extraction procedure was used to investigate metal speciation. Two bioavaile metal fractions were

  • Field Portable XRF for Agriculture: Environmental Quality

    ChallengeSolutionXRF SpecificationsReferencesThe safety of sources is becoming increasingly important as the human population expands. As the demand for sources has grown, precision agriculture and peri-urban farming are becoming more commonplace. However, farming in areas adjacent to industrial and other urban facilities raises questions about the safety of crops grown in soil or irrigated with water fraught with pollution.
