✦ Synopsis
Uranium concentrations in seawater ranging from background levels to a maximum of 2 mg L -I were determined by either the fission track method (direct or preceded by scavenging with chromic hydroxide) or delayed neutron analysis.
The same techniques were applied to study the uptake of uranium from the above seawaters and its distribution in various marine biota, including the mussel Mytilus edulis and the amphipod Allorchestes compressa.
The results indicated that these biota accumulate a significant quantity of uranium which depends on time and concentration, e.g. mussel flesh accumulated approximately 30 ~gU g-i (:b:y weight) after 30 days in seawater containing 2 mgU L -I.
