Evaluation of the Efficacy of the Stress Protein Response as a Biochemical Water Quality Biomonitoring Method.

摘要

Potential field validation sites were evaluated in June 1989. Soldier Creek, emanating from Tinker AFB, was selected because of its industrial/sewage effluent. Soldier Creek, emanating from Tinker AFB, was selected because of its industrial/sewage effluent. Soldier Creek is the largest tributary of Crutcho Creek, which empties into the North Canadian River. Twelve sites along the three water ways were evaluated. Water was collected from each site and transported on ice. Toxicity was determined by placing 90d fathead minnows into 1-gallon jars filled with 3L of sample water. Two sites immediately below Tinker AFB exhibited acute toxicity with total mortality occurring within 30 minutes of test initiation. However, all other sites, showed no toxicity. The free chlorine level was in the site immediately below Tinker AFB (site l) at all other sites. Thus, a toxicity and chemical gradient was found in Soldier Creek. Sediment collected at four sites, closest to Tinker AFB, smelled of fuel and solvents. Sediment toxicity was evaluated by placing 90d fathead minnows into 1 gallon glass jars filled 600 ml of Soldier Creek sediment overlaid with 2400 ml of Soldier Creek water. No toxicity was seen in any of the stations. (SDW)
