It can also be seen in Table 2 that the influent EDCs concentrations in urban wastewater (WWTP A and B) are higher than the rural wastewater (WWTP C and D).The average daily variations for the first sampling campaigns for site B is presented in Fig.…”

AB STRACT: Endocrine disrupting chemicals are discharged into the environment mainly through wastewater treatment processes. There is a need for better understanding of the fate of these compounds in the unit processes of treatment plant to optimise their removal. The fate of oestrone, 17β-estradiol, 17α-ethinyestradiol and nonylphenol in the unit processes of full scale wastewater treatment plants in the UK, including activated sludge plant, oxidation ditch, biofilter and rotating biological contactor were investigated. The overall removal efficiencies of all the compounds ranged from 41 % to 100 %. The removals were predominantly during the secondary biological treatment with the rates of removal related to the nitrification rates and the sludge age. The removal efficiency of the treatment processes were in the order activated sludge > oxidation ditch > biofilter > rotating biological contactors. Activated sludge plant configured for biological nutrient removal showed better removal of the endocrine disrupting chemicals compared to conventional activated sludge plant effluents. Tertiary treatment was also significant in the removal process through solids removal. Overall mechanisms of removal were biodegradation and sorption unto sludge biomass. Phytoremediation was also significant in the removal processes. The endocrine disrupting chemicals persisted in the anaerobic sludge digestion process with percentage removals ranging fro 10-48 %. Sorption of the endocrine disrupting chemicals onto the sludge increased with increasing values for the partitioning coefficients and the organic carbon contents of the sludge.

“…However, if an antibiotic concentration was below its LOQ, the removal efficiency was calculated following the rules proposed by Gabet-Giraud et al (2010). Specifically, when an antibiotic was detected at a concentration below its LOQ in both influent and effluent, the removal efficiency was not calculated; when an antibiotic was detected in the influent but not in the effluent, the removal efficiency was calculated using half of its LOQ value for the effluent.…”

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.

“…Regular examination of the levels of hormones in the inflow of different treatment plans in France also revealed the presence of the beta estradiol hormone with a concentration of 3.5 to 50 ng l -1 in all samples. Results of this study indicated that these compounds are present in the urban and rural wastewaters of this OCCURRENCE AND FATE OF 17β-ESTRADIOL IN WATER RESOURCES AND WASTEWATER 857 country (Gabet-Giraud et al, 2010). The presence of this hormone in hospital effluents is proved as well.…”

Estradiol is known as the indicator of the presence of hormones as Endocrine Disruptor Compounds (EDCs) in water and wastewater. The entrance of these compounds into water resources through daily liquid wastes of societies as well as pharmaceutical industries, ranching, and pathology laboratories leads to an increase in their concentrations in these resources. Consequently, due to the metabolic properties of these substances they can cause adverse effects on consumers and aquatics. The main purpose of this research is to determine the occurrence and the fate of estradiol as indicator of endocrine-disrupting compounds in drinking water, surface water, and wastewater in Ahvaz, Iran. 17β-estradiol was detected in 37.5% of samples obtained from drinking water and 68.75% of samples from the Karun River. In the urban drinking water and Karun River, the mean concentrations of 17β-estradiol were 2.96 and 13.66 ng l -1 , respectively.In the domestic and industrial wastewater, the concentrations of 17β-estradiol were higher than that detected in the drinking and surface waters. The mean concentrations of this hormone in these wastewaters were 57.46 and 70.6 ng l -1 , respectively. The highest amount of 17β-estradiol was measured in the hospital wastewater. The fate of 17β-estradiol in the slaughterhouse wastewater treatment plant, in which a septic tank, an anaerobic pond, and an aerobic tank were used for wastewater treatment, was higher than 75%. The highest level of removal in the aerobic stage was also obtained by breaking estradiol down to other metabolites.
