“…Fe analysis was carried out by inductively coupled plasma optical emission spectrometry (ICP/OES, IRIS Intrepid Typ Duo, Thermo Nicolet GmbH) at 259.9 nm, Al at 396.1 nm, and Zn at 206.2 nm (Nölte, 2003). Cd was measured in the same samples by GF-AAS (graphite furnace atomic absorption spectrometry) (Zeeman 4100-Perkin-Elmer) (Schlemmer and Radziuk, 1999).…”
