Item Investigation of trace elements in ancient pottery from Jenini, Brong Ahafo region, Ghana by INAA and Compton suppression spectrometry(Nuclear Instruments and Methods in Physics Research, Section B: Beam Interactions with Materials and Atoms, 2007-10) Nyarko, B.J.B.; Bredwa-Mensah, Y.; Serfor-Armah, Y.; Dampare, S.B.; Akaho, E.H.K.; Osae, S.; Perbi, A.; Chatt, A.Concentrations of trace elements in ancient pottery excavated from Jenini in the Brong Ahafo region of Ghana were determined using instrumental neutron activation analysis (INAA) in conjunction with both conventional and Compton suppression counting. Jenini was a slave Camp of Samory Toure during the indigenous slavery and the Trans-Atlantic slave trade. Pottery fragments found during the excavation of the grave tombs of the slaves who died in the slave camps were analysed. In all, 26 trace elements were determined in 40 pottery fragments. These elemental concentrations were processed using multivariate statistical methods, cluster, factor and discriminant analyses in order to determine similarities and correlation between the various samples. The suitability of the two counting systems for determination of trace elements in pottery objects has been evaluated. © 2007 Elsevier B.V. All rights reserved.
