The acute toxicity of five desensitized primer compounds and primer manufacturing waste effluents to three freshwater species, Daphnia magna water flea crustacean, Lepomis macrochirus bluegillfish and Pimephales promelas fathead minnowfish was determined in static bioassays. The primers tested were trinitroresorcinol TNR styphnic acid, lead styphnate PbTNR, tetracene, pentaerythritol tetranitrate PETN and FA 956 priming mixture. The waste effluents were those resulting from the production of TNR, PbTNR, tetracene and FA 956. In addition, a reagent blank which contained no primer materials but was desensitized by the procedure used for TNR, was also tested. To determine the effect of the high pH, resulting from the desensitization process, of test materials, bioassays were performed with Daphnia magna and Pimephales promelas exposed to neutralized versus unneutralized materials. Results indicated that, except for tetracene, the acute toxicity of the primers and waste effluents tested was due primarily to the high pH resulting from desensitization.
