Abstract

Uranium was determined in extracts of inter-tidal sediment, obtained from a contaminated harbour, using the three-stage sequential extraction procedure recommended by BCR. The element was found mainly in association with reducible, or reducible and oxidisable, phases and the overall concentration was enhanced (up to 6.7 mu g g(-1) dry weight) with respect to typical, UK levels. The (238)Ur-U-235 ratio has been measured in digests of stream sediments obtained from the vicinity of a uranium enrichment plant. Significant enhancement in U-235 with respect to the natural U-238/U-235 ratio (137.88:1) was observed at some locations.
