Figure 1

As phytofiltration experiment with P. vittata over 16 weeks. (a) Time course of As removal in medium with P. vittata (Fern) and without P. vittata (NC) over 16 weeks. After 4 weeks As phytofiltration experiment, (b) As concentration in fronds, rhizomes and roots of P. vittata. After 16 weeks As phytofiltration experiment, (c) As concentration in fronds, rhizomes and roots of P. vittata. (d) As concentration in different stages of fronds (fronds brown margin, fronds gray margin, fronds new) of P. vittata. (e) The dry weight of fronds, rhizomes and roots of P. vittata. (f) As amounts in fronds, rhizomes and roots of P. vittata. (g) As mass balance between As uptake by P. vittata and As decline from the medium. Data are expressed as mean + standard deviation (n = 3).
