Recebido em 21/8/06; aceito em 30/3/07; publicado na web em 6/8/07 PHYSICAL, CHEMICAL AND ECOTOXICOLOGICAL CHARACTERIZATION OF AN EFFLUENT FROM AN EXPLOSIVES INDUSTRY. The production and use of nitroaromatic explosives have resulted in their dissemination into the environment, where their presence in waterways and soil represents an ecological and health hazard. The hazardous characteristics of these compounds need to be carefully studied, so that the impact of their discharge on the environment can be better evaluated. This work presents the characterization of wastewater from Brazilian TNT industry using as analytical techniques mass spectroscopy, chromatography, toxicity assays and other physico-chemical analyses.
