Understanding of trace elements distribution in different soil chemical fractions and of the total mobility and concentration is essential for the diagnosis of contamination and the definition of remediation strategies for contaminated sites. This study aims to evaluate Cd behavior in the soil chemical fractions and Cd total concentration extracted by aqua regia of a Fluventic Dystrudept. After the contamination with increasing doses applied and incubation of the metal in the soil, samples were analyzed following the protocol described by GOMES et al. (1997) for sequential fractionation, and the ISO 11047 (1998) (aqua regia) for total extraction. Cd determination was performed by atomic absorption spectrometry. The results were subjected to...
