Trends in the occurrence of human and veterinary antibiotics in the sediments of the Yellow River, Hai River and Liao River in northern China

Occurrence, distribution and potential affecting factors of antibiotics in sewage sludge of wastewater treatment plants in China

“…It has been reported that the adsorptions of some antibiotics, such as tetracycline and quinolones, are related to organic carbon content of the soil and sediment (Jia et al, 2012;Pomati et al, 2004;Zhang et al, 2011;Zhou et al, 2011). Therefore, the contents of total organic carbon (TOC, %) in sludge samples were also investigated to assess the potential influence on the antibiotic levels.…”

Occurrence and fate of eleven classes of antibiotics in two typical wastewater treatment plants in South China

“…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).…”

Occurrence and distribution of antibiotics in urban soil in Beijing and Shanghai, China

“…Several studies have documented that antibiotics are not completely metabolized in the body and thus are excreted as the unchanged or transformed components into environment via urine and feces (Jjemba 2002;Kümmerer 2009;Sarmah et al 2006). Antibiotics have been detected in various environments, such as surface water (Jiang et al 2011;Tamtam et al 2008;Zou et al 2011), ground water and drinking water (Hu et al 2010;Watkinson et al 2009;Yiruhan et al 2010), sediment (Kim and Carlson 2007;Luo et al 2011;Zhou et al 2011), soil (Golet et al 2002;Hu et al 2010;Shi et al 2012;Tamtam et al 2011), and biological samples Love et al 2011;Zhao et al 2010).…”
