Caracterização física, química e ecotoxicológica de efluente da indústria de fabricação de explosivos

Abstract: 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 … Show more

“…These compounds are generally recalcitrant to biological treatment and constitute a source of pollution due to both their toxic and their mutagenic effects on humans, fish, algae and microorganisms [2][3][4][5]. The main source of nitrocompound contamination is associated with industrial processes, storage operations and use in military installations [1,2]. The discharge of residues generated during explosive manufacturing and processing as well as the associated level of contamination varies widely, depending on the intensity of the manufacturing operations and the effectiveness of the technologies used to treat the residues [6].…”

“…The composition of yellow water varies widely depending on the ammunition manufacturing processes [1]. However, among those toxic compounds, TNT is known as the major constituent of yellow water [2]. Due to the toxicity and possible carcinogenicity of TNT, these explosive compounds must be removed from wastewater before it is released into the environment [3][4][5].…”

“…Enquanto os efluentes industriais, geralmente, contêm altas concentrações de sólidos em suspensão, compostos nitrogenados, alta demanda bioquímica de oxigênio (DBO), demanda química de oxigênio (DQO), fenóis, sulfatos, cloretos, organoclorados, metais, derivados do petróleo e interferentes endócrinos (BARBOSA, 1995;BARRETO-RODRIGUES, 2007;GHISELLI;WILKE et al, 2008).…”

“…Historicamente, a toxicologia tem se concentrado nos efeitos adversos dos xenobióticos sobre os seres humanos e animais domésticos, após exposição direta (FERNICOLA, 2004). Já a toxicologia aquática é o estudo dos efeitos de substâncias químicas naturais e substâncias e/ou atividades de origem antropogênicas, em organismos aquáticos nos seus diversos níveis de organização, desde estruturas celulares até indivíduos, populações, comunidades e ecossistemas RODRIGUES et al, 2007;KOVACS et al, 2002;PABLOS et al, 2009;SIMS;STEEVENS, 2008;SOTERO-SANTOS, 2005;WILKE, 2008 Ensaios do potencial genotóxico de amostras de água (CARDOZO et al, 2006;LEMOS et al, 2009;UMBUZEIRO et al, 2001;VARGAS et al, 2008;) e de sedimentos (HORN et al, 2004;LEMOS et al, 2009;TAGLIARIet al, 2004;VARGAS et al, 2001) têm sido bastante utilizados para avaliar o impacto das atividades agrícolas, urbanas e industriais, configurando-se apropriados para avaliação de risco ambiental, ao evidenciar os danos ao DNA e posteriores alterações em organismos aquáticos em nível molecular, celular e tecidual.
