Any other information on results incl. tables
Neutron activation analysis revealed no enhanced content of SASIL in tissues compared to surrounding sediment. After 4 weeks exposure, 238 mg SASIL/kg were measured in tissues, and after additional 7 days exposure in SASIL-free sediment, 147 mg Sasil/kg were determined.
