It has been argued that the identification of the phytotoxic metal thresholds in soil should be
based on field-collected soil rather than on artificially-contaminated soils. However, the use …

The revegetation of soils affected by the historic pollution of an industrial complex in central
Chile was studied. Spontaneous and assisted revegetation and changes in the …

Abstract Copper (Cu), a redox-active transition metal, is known to be involved in protein
