Title: Acute toxicity screening of reservoir water and sediment

Technical Report ·
OSTI ID:5305431

Toxicological evaluation of forebay and transition area water column (overlying water) and sediment porewater (interstitial water) samples was initiated during the summer of 1990 as part of TVA's Reservoir Vital Signs monitoring. Twenty-four stations were identified for study using acute toxicity screening test methods with the freshwater rotifer Brachionus calyciflorus (Rotox{reg sign}) and light emitting bacteria Photobacterium phosphoreum (Microtox{reg sign}). No acute toxicity to rotifers was demonstrated in the first series of tests using water column and sediment samples from the locations selected for monitoring. Sediments from three locations indicated some toxicity based on Microtox{reg sign}, although all EC{sub 50} concentrations were greater than 100 percent sample.
