Access from EThOS:
Surface sediment samples were collected from 35 locations in Sulaibikhat Bay, Kuwait. Eleven core samples were also taken. As, Cd, Co, Cr, Cu, Hg, Ni, Pb and Zn concentrations were determined and, with the exceptions of As and Hg, element speciation was studied, using the BCR sequential extraction procedure. This allows the fractionation of trace elements into four phases, namely; exchangeable, reducible, oxidizable and residual. Grain sizes, TOC, carbonate, mineralogical and environmental data were also determined. The abundance of the elements, their geographical distribution, and their relationships with each other and with sediment and environmental parameters are described with reference to sediment quality guidelines and the index of geoaccumulation (Igeo). Multivariate statistical analyses have allowed the most important factors in retaining trace elements in sediments to be identified and quantified.
