Occurrence and removal of pharmaceuticals and endocrine disruptors in South Korean surface, drinking, and waste waters

Biodegradation of sulfamethoxazole: current knowledge and perspectives

“…Pilot-scale reactors have demonstrated consistent results with SMX removal rates ranging from 52 to 70 % regardless of initial SMX concentration (145 ng/L to 20 μg/L) (Clara et al 2005;Kim et al 2007;Reif et al 2008). Lab-scale MBR studies (9 and 14 L) have demonstrated SMX degradation as a function of pH and powdered activated carbon (PAC) dose.…”

Monitoring of selected estrogenic compounds and estrogenic activity in surface water and sediment of the Yellow River in China using combined chemical and biological tools

“…Chemical analysis using gas chromatographyemass spectrometry (GCeMS) or liquid chromatographyetandem mass spectrometry (LCeMS/MS) has developed rapidly to provide better systems for identifying EDCs in the environment (Chen et al, 2010;Kim et al, 2007;Ko et al, 2007;Kolpin et al, 2002;Labadie and Hill, 2007;Micic and Hofmann, 2009;Ying et al, 2009). Several in vitro bioassays (e.g.…”

Isolation and characterization of sulfonamide-degrading bacteria Escherichia sp. HS21 and Acinetobacter sp. HS51

“…Some studies have focused on the removal of sulfonamides from the environments, but little research has been done on the biodegradation of sulfonamides (Jones et al 2001;Heberer 2002;Sukul and Spiteller 2006;Kim et al 2007). Biodegradation of sulfonamides present in wastewater treatment plants (WWTPs), surface water, manure and soils was summarized by Jesús García-Galán et al (2008).…”

“…Biodegradation of sulfonamides present in wastewater treatment plants (WWTPs), surface water, manure and soils was summarized by Jesús García-Galán et al (2008). Sulfonamides appeares to resist natural biodegradation rather strongly, which is reflected in the high frequency of their detection in streams and rivers (Kim et al 2007;Vieno et al 2007;Barnes et al 2008;Focazio et al 2008). Kuhn and Suflita (1989) reported the anaerobic biodegradation of para-toluenesulfonamide and benzenesulfonamide in aquifer slurries from a sulphate-reducing and methanogenic site.…”
