“…After administration, some of their residues would be excreted and finally end up in the receiving environment (Miao et al, 2004;Yang et al, 2011;Zhou et al, 2011;Zhou et al, 2013a, b, c). Previous studies showed detection of SMZ and TMP in wastewaters, manures and sludge of animal farms and municipal wastewater treatment plants (Hoa et al, 2011;Sim et al, 2011;Zhou et al, 2013a, b, c). Due to application of wastewaters and sludge on agricultural soils, antibiotics such as SMZ and TMP have been reported in soil environments (Li et al, 2011;Zhou et al, 2013a).…”

“…Indeed, the occurrence of sulfonamide residues, including those of SMX, in river water correlated positively with the presence of sulfonamide resistance genetic determinants [10]. Sulfonamide resistance in water habitats can reach values up to 94% [11], being observed in many commensal and pathogenic bacteria, in particular multidrug resistant [12]. Moreover, sulfonamide resistance genes, often associated with mobile genetic elements, have a widespread distribution in the environment [13].…”

This study aimed to isolate and characterize a microbial culture able to degrade sulfonamides. Sulfamethoxazole (SMX)-degrading microorganisms were enriched from activated sludge and wastewater. The resultant mixed culture was composed of four bacterial strains, out of which only Achromobacter denitrificans PR1 could degrade SMX. This sulfonamide was used as sole source of carbon, nitrogen and energy with stoichiometric accumulation of 3-amino-5-methylisoxazole. Strain PR1 was able to remove SMX at a rate of 73.6 ± 9.6 µmolSMX/gcell dry weight h. This rate more than doubled when a supplement of amino acids or the other members of the mixed culture were added. Besides SMX, strain PR1 was able to degrade other sulfonamides with anti-microbial activity. Other environmental Achromobacter spp. could not degrade SMX, suggesting that this property is not broadly distributed in members of this genus. Further studies are needed to shed additional light on the genetics and enzymology of this process.

“…In Asia, the antibiotic concentrations such as Oxytetracyclin, Trimethoprim and Sulfamethoxazole are high in both wastewater influent effluent and surface water [10]. In additional, researcher analyzed for 10 NSAIDs, 2 blood lipid regulators, and 2 antiepileptic drugs in the Pearl River system in China (Liuxi, Zhujiang, and Shijin Rivers) and four sewage effluents during the dry and wet seasons, results were reported and the environmental risks they posed were assessed [11].…”

Abstract. Southeast Asia countries were developing countries, with the rapid development for a better living condition leads to longer life expectancy, which increased total population. It may result in increased the demand of pharmaceutical in domestic use and or in hospital. Although most wastewater treatment plants (WWTPs) met the local authority's regulatory requirement, there are still many pharmaceutical compound incompletely removed and discharge to the water stream and enter the environment. Recently many studies and researches have published on the occurrence and source as well as the fate of pharmaceuticals all over the world including Asia. As part of Asia region, Southeast Asia countries (Malaysia, Philippines, Singapore, Thailand, Vietnam, Brunei, Cambodia, and Lao PDR) seem has lack of research knowledge and information regarding this emerging pollutant issues compared to developed Asia country as China, Korea and Hong Kong. In this paper, it will review recent studies occurrences (surface and wastewater) on most common pharmaceuticals with several recommendations to overcome and thus summarise the actual situation in Southeast Asia.
