Chemical characterisation of various archaeological soil samples using main and trace elements determined by inductively coupled plasma atomic emission spectrometry

• In this study a method has been developed to classify archaeologically related soil samples by means of multivariate statistical analysis (principal component analysis) of determined trace and main component concentrations. The Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES) technique was used for the determination of Fe, As, Cu, P, Mn, V, Co, Mo, Zn, Cr, Pb and Ca, and good accuracy was achieved by calibration against a certified reference material. It was shown that Cu, P, Mn, Zn and Ca were accumulated in feature and dwelling samples from a late bronze age site, Vistad, in southeast Sweden. Elements like Fe, V, Co and Cr characterized the control samples (from a surrounding field). It was also demonstrated that in this case, a simpler pretreatment procedure—acid extraction—could be used instead of total dissolution of the samples. Microwave heating was utilized for both procedures.
