Abstract
The newly implemented Dynamic Analysis method for on-line elemental im aging was used to study Ni hyperaccumulation in Senecio coronatus (Thu nb.) Harv. Asteraceae, one of only nine Ni hyperaccumulating plants fo und in the African continent. Elemental maps were obtained from sample s with thicknesses varying from 0.4 to 5 mg/cm(2) by assuming cellulos e (C6H10O5) as constant matrix composition for the whole scanned area. The agreement between point analyses and results inferred from maps i s good for small thickness variations within scanned regions. Maps of very inhomogeneous samples require a more time-consuming approach of t hickness corrections in every pixel.
