Title: Toxicity of Uranium Adsorbent Materials using the Microtox Toxicity Test

Abstract

The Marine Sciences Laboratory at the Pacific Northwest National Laboratory evaluated the toxicity of a diverse range of natural and synthetic materials used to extract uranium from seawater. The uranium adsorbent materials are being developed as part of the U. S. Department of Energy, Office of Nuclear Energy, Fuel Resources Program. The goal of this effort was to identify whether deployment of a farm of these materials into the marine environment would have any toxic effects on marine organisms.

  • Results were correlated from the Microtox assay and the whole effluent acute toxicity test for effluents from the (1) wastewater treatment plant (WWTP) and (2) terminal ponds located at the Rocky Flats Plant. Literature reviews indicate that Photobacterium phosphoreum (Microtox assay) may be used as screening test for the reaction of Ceriodaphnia dubia and Pimephales promelas to toxins present in effluents. This study indicates that the Microtox is less sensitive to toxins present in the WWTP effluent than other test organisms (Ceriodaphnia dubia and Pimephales promelas). Toxicity appears to be from unionized ammonia. Ten months of data reveal that themore » surface water effluents which leave Rocky Flats boundaries are non-toxic when judged by all three test organisms.« less
  • Toxicological screening of reservoir sediments (porewater or interstitial water) and reservoir water (collected three meters above the sediments) was initiated in fourteen Tennessee River mainstem impoundments during the summer of 1990 as part of TVA's Reservoir Vital Signs monitoring. Twenty-four stations representing transition-zone and forebay reservoir habitats were identified for study. Toxicity test methods evaluated acute response of the freshwater rotifer Brachionus calyciflorus (Rotox[trademark]) and the light emitting bacterium Photobacterium phosphoreum (Microtox[trademark]). The second series of Vital Signstoxicity biomonitoring tests was conducted during the summer of 1991. Results of this study indicated toxicity at several locations. The Vital Signs Reservoirmore » Monitoring project allows several years of testing to establish toxicity baseline data and identify trends. Comparison of results from the first two years of testing show that Wilson Reservoir forebay (TRM 260.8) and Nickajack Reservoir forebay (TRM 425.5) bothexhibited mild toxicity to Microtox[trademark] in 1990 and toxicity to rotifers in 1991. No other stations exhibited toxicity both years.« less
  • Toxicological evaluation of water column and sediment samples from six locations in the Ambient Stream Monitoring fixed station network was initiated in 1986 using short-term chronic bioassay methods. Toxicological evaluation of six additional stations was initiated in 1990. Chronic studies were conducted at one of these new stations and acute screening methods were used at all twelve locations now included in the activity. This report provides results from studies conducted during the summers of 1990 and 1991. The 1990--91 studies evaluated toxicity of stream water and porewater extracted from sediments as test media, whereas previous studies evaluated water and sedimentmore » elutriate samples.« less
