Toxicity of DEDGN (Diethyleneglycol Dinitrate), Synthetic-HC Smoke Combustion Products, Solvent Yellow 33 and Solvent Green 3 to Freshwater Aquatic Organisms

摘要

The acute toxicities of four munitions compounds to nine freshwater aquatic organisms were determined. The munitions were: diethyleneglycol dinitrate (DEGDN), solvent yellow 33, solvent green 3, and synthetic-HC smoke combustion products which are a complex mixture containing Zinc, Cadmium, Arsenic, Lead, Aluminum, Carbon Tetrachloride, Perchloroethylene, Hexachloroethane, Hexachlorobenzene, and Hydrochloric acid. Fish exposed to the materials for 96 h included the fathead minnow (Pimephales promelas, bluegill (Lepomis macrochirus), channel catfish (Ictalurus punctatus and rainbow trout (Salmo gairdneri). Invertebrates, which were exposed for 48 h, included the water flea (Daphnia magna), amphipod (Gammarus pseudolimnaeus), midge larva (Paratanytarsus parthogenetica) and mayfly larva (Hexagenia bilinata). Growth of the green alga (Selenastrum capricornutum was also tested with all the compounds.
