Dissolved Solids as HD Bioeffluent Toxicants.

Abstract

The U.S. Army, through the Alternative Technology Program at Aberdeen Proving Ground, MD, has developed a neutralization/biodegradation process that treats hydrolyzed sulfur mustard. The effluent produced from this process has been proposed to be discharged to a Federally Owned Treatment Works. Chronic toxicity studies have shown that the effluent from the bioreactors is toxic to ceriodaphnia and fathead minnows. The effluent contains 2.4% salt, which is not tolerated by freshwater organisms. The purpose of this study was to determine if the salt in the effluent was the major contributor to the toxicity. Acute toxicity studies were conducted using ceriodaphnia exposed to a mixture of bloeffluent and synthetic effluent. Results have shown that the salts were the major cause of bioeffluent toxicity.
