Alterations in soil microbial activity and N-transformation processes due to sulfadiazine loads in pig-manure

Removal of antibiotics and antibiotic resistance genes from domestic sewage by constructed wetlands: Optimization of wetland substrates and hydraulic loading

“…After administration, antibiotic residues can be released into the receiving environments through discharge of the feces or urine, thus posing potential risks to human health and ecosystem (Costanzo et al, 2005;Kotzerke et al, 2008;Liu et al, 2009;Underwood et al, 2011). Use of antibiotics in humans and animals could also lead to development and spread of antibiotic-resistant bacteria (ARB) and antibiotic resistance genes (ARGs) in the environment (Pruden et al, 2006;Tao et al, 2010;Su et al, 2012).…”

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

“…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). In order to reduce the negative impacts on the environment and human health, it is necessary to understand the input sources for various classes of antibiotics.…”

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

“…Some antibiotics can be biodegraded within a few days in soil (Burkhardt and Stamm 2007;Kotzerke et al 2008), while some other antibiotics can be persistent in soil with the half-life time of several months (Marengo et al 1997;Rosendahl et al 2012). The antibiotics, such as tetracyclines and quinolones (QNs), exhibit high adsorption properties to accumulate in soil on the surface of either mineral or organic soil constituents (Tolls 2001).…”
