De analyses zijn uitgevoerd in de fractie 63 mu m van 14 lokaties en in het totale monster van 6 lokaties. Het onderzoek was ongeveer analoog aan dat in de jaren 1990 t/m 1992. In het algemeen nemen de concentraties van microverontreinigingen af in de richting van de Noordzee, als gevolg van een toename van het aandeel van relatief schoon marien sediment in de waterbodem in dezelfde richting. Ten opzichte van de concentraties in hun omgeving zijn relatief hoge concentraties gemeten van arseen, koper en lood op de drempel van Hansweert; van kwik op de drempel van Bath; van koper op de drempel van Krankeloon; en van PAKS nabij Terneuzen en Bath. De resultaten van de analyses aan de monsters van 1993 zijn vergeleken met die van de voorgaande jaren aan de hand van de verhouding met aluminium voor wat betreft de metalen en de verhouding met
