The two dimensional XRF mapping of G pulex was
pulex, bulk XAS analysis was carried out (using XANES) on one specimen and micro-XANES data were collected from different spots of different As intensity on another specimen used for mapping ( Table 1). XANES measurements were also obtained for a leaf sample. Bulk XANES measurements of G. pulex showed 78% As(V)–O, 20% As(III)–O and 2% MMA ( Table 1).
