Recent research data on the removal of pharmaceuticals from sewage treatment plants (STP)

Abstract: Recebido em 12/12/08; aceito em 24/7/09; publicado na web em 8/1/10 Pharmaceutical compounds have been detected in sewage treatment plant (STP) effluents, surface waters and, less frequently, in groundwater and drinking water, all over the world. Different sources are responsible for their appearance in the aquatic environment, however, it is widely accepted that the main sources of this type of pollutant are STP effluents. The adverse effects of pharmaceuticals in the environment include aquatic toxicity, dev… Show more

“…Consequently, pharmaceuticals have been detected in surface waters, wastewaters, soils, sludges and sediments across the globe [5,[8][9][10][11]. While the concentrations of these substances in the environment are low and therefore are unlikely to cause acute effects on organisms, it is possible that chronic and subtle effects could occur [12,13]. A range of chronic and subtle effects, including feminization of male fish and effects on wildlife behaviour, have been observed under laboratory conditions with effect concentrations being similar to those measured in the environment, [14][15][16].…”

“…A toxicidade observada, principalmente nos testes agudos, que avaliaram as amostras em concentrações menos diluídas, parece estar relacionada ao Al 2 (SO 4 ) 3 . Porém outro fator que pode ter influenciado no aumento da toxicidade dessas amostras é a formação de produtos intermediários de degradação com toxicidade igual ou maior que a dos compostos vindos diretamente da produção dos medicamentos (Tambosi et al, 2010;Fatta-Kassinos et al, 2011).…”

“…A adsorção é dependente de interações hidrofóbicas e eletrostáticas dos fármacos com partículas e bactérias em suspensão. Porém, quando os fármacos estão presentes preferencialmente na fase solúvel, o processo de eliminação mais importante é a biodegradação (Tambosi et al, 2010). A degradação pode ocorrer em zonas aeróbias (e em alguns casos anaeróbias) nos tratamentos por lodos ativados, e no geral a decomposição biológica de fármacos aumenta com o aumento do tempo de retenção hidráulica e com a idade do lodo (Tambosi et al, 2010).…”
