Geochemical, mineralogical and grain size data from sediment cores in the Lamjana Bay shipyard were obtained to determine the Toys extent of contamination due to ship refits.The concentration and distribution of Ni, Pb, Cr, Zn, Cu, Mn, Cd, As and Fe in 9 sediment samples were measured.No increase of the analysed elements above natural background levels was detected, but contamination was not excluded due to possible DESK dilution of seabed sediment by quartz sand used in process of abrasive blasting.
