Risk of Pore Water Ammonia Toxicity in Dredged Material Bioassays. Dredging Operations Technical Support Program.
Abstract
Ammonia is a highly toxic, naturally occurring constituent of sediment pore water. It is not treated as a contaminant of concern for the regulatory evaluation of dredged material since it undergoes rapid oxidation and dilution during dredging and disposal. Because dredged material is evaluated using effects-based tests (i.e., whole sediment and elutriate toxicity tests), there is the potential for ammonia to exert toxicity and confound the regulatory decision-making process. This report evaluates the potential for ammonia toxicity in dredged material bioassays.
