Pteris vittata is known to hyperaccumulate arsenic, and a large number of studies on this fern species can be found in the literature aimed at evaluating its behavior when coexposed to other toxic elements. In the present study, P. vittata was treated with different concentrations of As and/or Cd in a hydroponic system, that is, under complete...

Zn uptake and compartmentalisation were studied in two ferns, the European Polypodium cambricum L., a possible Zn tolerant, and the sub-tropical Pteris vittata L., an As accumulator also able to accumulate Zn. Ferns growing in hydroponic systems were exposed to Zn concentrations ranging from non-toxic to lethal doses (0, 50, 125, 250, 500 mg/kg...
