Within a set of various fertilizer samples, main and trace elements were determined with ICP-OES after dissolution with hydrochloric acid, or ashing with subsequent dissolution, respectively. In spite of high P contents, ICP-OES gave reliable results when compared to conventional AAS determinations. With respect to previous investigations, trends in Cd, Cr, Zn and Ni contents of fertilizers were observed. The solid samples were also submitted to magnetic susceptibility measurements. Similarly, a set of soil samples from a remote plain area in the East of Austria was investigated for aqua regia leachables and magnetic measurements. High magnetic susceptibility was found only in basic slag and basic slag potash. Other fertilizers were much lower in magnetic susceptibility than the soils investigated. Thus, fertilization would not interfere with magnetometric profiling for the detection of environmental contaminations in the field.
