Abstract In this study, statistical analysis and spatial distribution were performed to compare raw data centred log-ratio ( clr ) transformed of three copper (Cu), lead (Pb), zinc (Zn) potentially toxic elements (PTEs) concentration for 550 surface soil samples in Khuzestan plain. The results both approaches showed that classical univariate compositional are essential find the real structure c...

The objectives of this study were to establish geochemical background values aluminum (Al), iron (Fe), arsenic (As), barium (Ba), cadmium (Cd), cobalt (Co), chromium (Cr), copper (Cu), manganese (Mn), nickel (Ni), lead (Pb), vanadium (V), and zinc (Zn) for eastern Amazon soils assess the relationship between soil chemical granulometric attributes using univariate multivariate procedures.
