Environmental soil quality of the city of Aveiro

Urban soils were analysed in 77 sites and 2 depths. Several parameters considered as general indicators of soil quality of the soils were measured: soil pH, organic C, total N, H, S, size distribution analysis (sand, silt, clay), cation exchange capacity, and contents of several metals that are considered as potential pollutants: Cd, Cr, Cu, Ni, Pb and Zn, and also Fe and Mn as metals that can be considered to be unlikely to be influenced by human intervention. The metal contents were determined by digestion with aqua regia and analysed by ICP-OES. This represents the metal forms of greater environmental interest ("pseudo totals").
