| Ten native terrestrial plants from soils polluted by former mining activities (Mónica mine, NW Madrid, Spain), with high total arsenic concentration levels (up to 3,500 µg/g), have been studied to determine the fraction of arsenic present as toxic forms (inorganic and methylated species), which present a higher mobility and therefore the potential risk associated to their reintegration into the environment is high. Roots and aboveground parts were analyzed separately, to assess possible transformations from translocation processes. Extractions were carried out with deionized water by microwave-assisted extraction, at a temperature of 90 ºC and three extraction steps of 7.5 min each. Total extracted arsenic concentrations were determined by inductively coupled plasma atomic emission spectrometry, whereas speciation studies were performed by high performance liquid chromatography-photo-oxidation-hydride generation-atomic fluorescence spectrometry. | |
