“…For most of the pharmaceuticals investigated, the recovered mass and estimated concentration of a given compound in the downstream sample was significantly higher than in the sample upstream from the WWTP discharge structure. This result indicates that WWTP effluent is a significant source of pharmaceutical loading to the receiving waters, a finding in agreement with other studies which have also demonstrated WWTP effluent to be a significant source of pharmaceutical loading to the environment (Batt et al, 2006;Kim et al, 2007;Lee and Rasmussen, 2006;Roberts and Thomas, 2006). The pharmaceuticals that were detected in all sampling locations (upstream of discharge structure, downstream of discharge structure, and effluent) were caffeine; 1,7-dimethylxanthine, a caffeine metabolite; cotinine, a nicotine metabolite; DEET, and diphenhydramine.…”

“…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).…”

“…HRT is another important factor for the removal of micro-pollutants in WWTPs. Batt et al (2006) pointed out that a longer HRT generally resulted in a higher removal efficiency of micro-pollutants. The HRT of the CW ranged from 24 to 120 h, which was significantly higher than that of the AS (Table 1).…”

a b s t r a c tThe occurrence and removal of 19 antibiotics (including four macrolides, eight sulfonamides, three fluoroquinolones, three tetracyclines, and trimethoprim) were investigated in two ecological (constructed wetland (CW) and stabilization pond (SP)) and two conventional wastewater treatment processes (activated sludge (AS) and micro-power biofilm (MP)) in a county of eastern China. All target antibiotics were detected in the influent and effluent samples with detection frequencies of >90%. Clarithromycin, ofloxacin, roxithromycin and erythromycin-H 2 O were the dominant antibiotics with maximum concentrations reaching up to 6524, 5411, 964 and 957 ng/L, respectively; while the concentrations of tiamulin, sulfamerazine, sulfathiazole, sulfamethazine, sulfamethizole and sulfisoxazole were below 10 ng/L. Although the mean effluent concentrations of target antibiotics were obviously lower than the influent ones (except ciprofloxacin), their removals were usually incomplete. Principal component analysis showed that the AS and CW outperformed the MP and SP processes and the AS performed better than the CW process in terms of antibiotics removal. Both the AS and CW processes exhibited higher removal efficiencies in summer than in winter, indicating biological degradation could play an important role in antibiotics removal. Because of the incomplete removal, the total concentration of detected antibiotics increased in the mixing and downstream sections of a local river receiving the effluent from a typical wastewater treatment facility practicing AS process. Nowadays, ecological wastewater treatment processes are being rapidly planned and constructed in rural areas of China; however, the discharge of residual antibiotics to the aquatic environment may highlight a necessity for optimizing or upgrading their design and operation.
