“…A current drawback of these samplers is that to measure the amount of chemical adsorbed, the sampler must first be calibrated for the target compounds by determining their sampling rates (R s in Ld − 1 ). Since the technology is still developing, many uptake rates have yet to be determined and R s obtained in the laboratory can be quite different from those in the field (Bailly et al, 2013). In addition, fouling and clogging of POCIS, especially in untreated wastewater can limit its deployment time.…”

• 19 drugs of abuse were studied throughout a wastewater treatment plant.• Drug levels were generally comparable between composite, POCIS and grab samples.• Overall drug removals during wastewater treatment varied between −84 and 90%.• Time-shifted mass balancing eliminated negative removals obtained with other approaches. In this study the levels of 19 drugs of abuse were estimated throughout a wastewater treatment plant using polar organic chemical integrative samplers (POCIS), 24 h composite samples and grab samples. Overall removal efficiencies and removals in between each treatment unit were calculated using load data for each sampling technique as well as removals that take into account the hydraulic residence time distribution of the treatment plant (time-shifted mass balancing approach). Amphetamine-type stimulants, cocaine and its major metabolite, benzoylecgonine and opioid levels determined with 24 h composite samples were generally comparable to those obtained with POCIS and grab samples. Negative mass balances resulting from the estimation of overall removal efficiencies by POCIS, day-to-day mass balancing of 24 h composite and grab sample data did not occur when the hydraulic retention time (HRT) distributions of the plant were taken into account for calculation. Among the compounds investigated, cocaine exhibited the highest overall removal (90%) while codeine had the lowest with 13%, respectively. Sampling between the treatment units revealed that highest removal occurs during biological treatment as compared to primary or secondary clarification. Methylenedioxyamphetamine (MDA), fentanyl, dihydrocodeine and heroin were not detected in wastewater at any of the sampling locations at the treatment plant regardless of the sampling technique. The study demonstrates the benefits of applying the time-shifted mass balancing approach to the calculation of removals of drugs of abuse during wastewater treatment. a b s t r a c t a r t i c l e i n f o

“…The polar functional groups (carboxylic moieties, aldehydes and amines) of these compounds may interact with suspended organic materials and lead to their high concentration in sewage sludge (Ternes et al, 2004;Carballa et al, 2008). Due to the lack of reliable analytical methods, most previous studies have focused on the water phase of pharmaceuticals in sewage (Ort et al, 2010;Bailly et al, 2013). In fact, most biological wastewater treatment plants have high removal efficiencies for pharmaceuticals resulting from the sorption and sedimentation of these products into the sludge (Jelic et al, 2011;Jia et al, 2012).…”

h i g h l i g h t sPharmaceutical residuals were analyzed for sludge samples from 45 sewage treatment plants in China. Fluoroquinolone and tetracycline were the dominant antibiotics. Other pharmaceuticals such as ketoprofen and ibuprofen also in significant presence. Poor agreement found between the detected and predicted concentrations. t r a c tThe presence of pharmaceuticals in aquatic environment has become a topic of concern because of their potential adverse effects on human health and wildlife species. A total of 45 dewatered sewage sludge samples were collected throughout China and analyzed for 30 commonly consumed pharmaceutical residues. Ofloxacin was found to be the dominant contaminant with concentrations up to 24 760 lg kg ). The concentration of pharmaceutical residues varied greatly depending on the operation conditions of wastewater treatment plants and sampling locations. Poor agreement was found between the predicted (calculation based on the annual consumption and coefficient of sludge water partition) and detected concentrations of the pharmaceuticals indicating that the occurrence of pharmaceutical residues was affected by various factors such as loading rates, sewage properties and the chemical properties such as the contribution from polar groups. National wide fate and ecotoxicity study is required for the development of control strategies.

“…Although some reports suggested that the R s values significantly increased with the flow velocity, [22][23][24] one report suggested that there was less than a twofold increase in accumulated amounts between 0.026 and 0.37 m/s. 25) Harman et al 26) concluded that flow correction might not be necessary in some studies where water flow rates varied over the range studied; therefore, we did not adjust the R s values.…”

The monitoring of pesticide concentrations in Japanese rivers was conducted via a grab sampling method and a passive sampling method using the polar organic chemical integrated sampler (POCIS). The results showed that cumulative detections were 84 with grab sampling and 98 with the POCIS. All of the pesticides detected by grab sampling could be quantified with a POCIS except for one (although its traces were detected). In addition, 15 detections quantified by POCIS were undetected by grab sampling. The average concentrations of pesticides detected by both the POCIS and grab sampling during the investigation period were compared. A good correlation was observed between the two methods with a slope of 1.00 and a coefficient of correlation (r) of 0.897 (n=79). Although high temporal variability was observed in the pesticide concentrations by grab sampling, the average pesticide concentrations obtained by the two methods showed similar values during the investigation period.
