“…The antibiotic sulfamethazine has been reported in groundwater several studies (n=5), with maximum concentrations ranging from 120-616 ng/L, and the highest concentrations being associated with leaching from farm waste lagoons, although it has also been reported in groundwater reconnaissance studies in Germany, USA and Switzerland (Hirsch et al, 1999;Barnes et al, 2008; NAQUA, 2009). Two other veterinary antibiotics reported in groundwater include monensin and tylosin (Watanabe et al, 2008; Bartel-Hunt et al., 2011).…”

“…isolates discharged to the environment after conventional activated sludge (CAS) WW treatment (Zhang et al 2009) and the detection of antibiotic resistance genes in surface water to which highly treated municipal WW is discharged (LaPara et al 2011). The estimated antibiotic consumption worldwide ranges from 100,000 to 200,000 t annually (Wise 2002), and due to excretion (which can reach up to 90 % of the ingested amount both as the original parent compound or as metabolites) (Daughton and Ternes 1999;Kümmerer 2009c) and disposal, up to microgram-per-liter levels have been detected in untreated WW (Hirsch et al 1999;Kümmerer 2009a, c, b;Perez et al 2005).…”

“…Various antibiotics have been frequently detected in groundwater Batt et al, 2006a), drinking water (Focazio et al, 2008), surface water (Hirsch et al, 1999;Yang et al, 2011), sediment (Zhou et al, 2011) and agricultual lands (Hu et al, 2010;Karci and Balcioglu, 2009). Wide occurrence of antibiotics in the environment could affect aquatic and terrestrial organisms (Costanzo et al, 2005;Kotzerke et al, 2008;Liu et al, 2009), alter microbial activity and community composition (Underwood et al, 2011), and lead to prevalence of bacterial resistance to antibiotics (LaPara et al, 2011;Su et al, 2012;Tao et al, 2010).…”
