“…Sulfonamides (SAs) represent one important class of antibiotics commonly used in veterinary and human medical practices because of their broad antimicrobial spectrum, strong antibacterial activity, stable chemical property, and low price (Hess et al, 1999;Huang et al, 2012). SAs are amphoteric and water-soluble compounds with a high environmental mobility (Dirany et al, 2012), so their traces are ubiquitous in almost all waters (e.g., waste, surface, ground, and drinking waters) (Lanuza, 2010;Capdeville and Budzinski, 2011;Fatta-Kassinos et al, 2011). Even though no direct human health effects have been reported (Le et al, 2005), SAs tend to bio-accumulate and have potential adverse effects on aquatic and terrestrial ecosystems by interrupting the normal activities of some microorganisms as well as developing and spreading antibiotic resistance genes (Elmolla and Chaudhuri, 2010;Rivas et al, 2011;Yuan et al, 2011).…”

“…3 Dentro deste contexto, deve ser dado destaque a processos de contaminação envolvendo ftalatos, a partir de fontes de contaminação que podem ser evidentes (por exemplo, mangueiras e vasilhames plásticos) 13 ou não tão evidentes (como ar atmosférico, solventes, materiais de vidro e septos de borracha, dentre outros). 14 …”

“…Em publicação recente, 3 foram discutidos os principais problemas encontrados na determinação de micropoluentes em amostras de água, particularmente a ocorrência de contaminações que levam a resultados falso-positivos e de perdas associadas à obtenção de resultados falso-negativos. Dentro do contexto dos problemas de contaminação salientam-se contribuições das etapas de coleta, armazenamento e transporte; das condições ambientais do laboratório, da qualidade dos equipamentos e insumos utilizados e, ainda, de contaminações associadas à manipulação por parte do analista, enquanto que em relação às perdas de espécies de interesse salienta-se a capacidade de recuperação das técnicas de extração, as quais costumam ser fortemente influenciadas pela composição da matriz.…”

“…In this context, pesticides, pharmaceuticals, personal care products (PPCPs), polycyclic aromatic hydrocarbons (PAHs), textile dyes, and other substances can threaten the quality of water resources, because they are generally toxic and non-biodegradable. [4][5][6] Recent studies have reported the risk of water contamination by pesticides in Southern Brazil and detected pesticides in ground, surface and drinking waters. [7][8][9] In this context, finding a method to reduce the impact of these pollutants is of great relevance.…”
