• Cobalt, Cr, Cu, Fe, Mn, Ni, Pb, Zn and As concentrations in the grain size and elemental normalization using Fe in gravel-free total soil ((X sub(m)/Fe) sub(total sample); X sub(m) = Cu, Pb, Zn, etc.) were used to determine the influence of variable grain size on the concentration of anthropogenic trace metal contaminants in the reclaimed area adjacent to Port Jackson, Sydney, Australia. Trace metal concentrations in soils in reclaimed area are greatly influenced by the heterogeneous nature of the waste materials buried at the site. The confounding effects of variable grain size in soils can be reduced by analyzing the contaminant concentration of the material after removing > 2 mm size in sample. An example from Sydney Harbour is used to demonstrate the comparability between grain size normalized data and elemental normalized data using Fe in soils from reclaimed areas. Results from the current study reveal that the vertical distribution of trace metal concentrations in soils is remarkably similar between the grain size and elemental normalization, using Fe. Normalization methods might be beneficial in overcoming texturally driven variations of contaminant concentrations in soils in the reclaimed or infilled land area.
