Aquatic Toxicity Screening of an ACWA Secondary Waste, GB-Hydrolysate
Abstract
The Assembled Chemical Weapons Alternatives (ACWA) Program has been tasked to demonstrate alternative technologies to incineration that will safely dispose of assembled chemical munitions. The ACWA program is currently investigating GB-hydrolysate as a secondary waste that can be transported offsite to a commercial Treatment Storage and Disposal Facility (TSDF). The Microtox assay with bioluminescent marine bacterium Vibrio fischeri and the survival and reproduction of freshwater organism Ceriodaphnia dubia were used to investigate the aquatic toxicities of ACWA GB-hydrolysate or the neutralized (pH adjusted) ACWA GB-hydrolysate. The Microtox assay was also used to assess the aquatic toxicity of Bluegrass Depot GB-hydrolysate. The 5-min EC50 values for V. fischeri exposed to either ACWA GB-hydrolysate or neutralized ACWA GB-hydrolysate were 0.24 and 28% vol/vol, respectively. The 5-min EC50 values for V. fischeri exposed to Bluegrass GB-hydrolysate or neutralized ACWA GB-hydrolysate were 0.05 and 4.7% vol/vol, respectively. The 24-hr EC50 values for C. dubia exposed to either ACWA GB-hydrolysate or neutralized ACWA GB-hydrolysate were 0.8 and 1.3% vol/vol, respectively.
