A Spectroscopic Approach to Assess Trace-Heavy Metal Contents in Contaminated Floodplain Soils via Spectrally Active Soil Components

Soil samples from grassland plots in the Hase floodplain near Osnabruck (NW Germany) were analyzed using visible and near-infrared laboratory spectroscopy (VNIRS) by means of an ASD FieldSpec II Pro FR- spectroradiometer (spectral range 0.4-2.5 mu …
