RESUMO
Among the instrumental techniques that can be useel for eletermination of trace elements in soils inductively coupled plaSl1la mass spectroscopy (ICP-MS) presents aelvantages such as multielemental character and superb sensitivity. However, aspects such as the content of total e1issolveel solids anel the polyatomic íons formeel in complex matrices may limit its application. The determination of Cr. Cu and V may suffer from polyatomic intelierences either originated in the argon plasma 01' in the matrix. In the case of 65Cu+ the main interferents are 23Na40Ar+ anel 23Na40Ca+ The eletermination of 52Cr+ is affecteel by 40Ar12C+ and 51V+ is affected by 35Cl16O+. Notwithstanding, all these elements also have less abundant isotopes not affected by severe interference processes.
