“…Recoveries outside the acceptable range might be associated with the matrix complexity of a samples and/or physicochemical properties of target compounds, such as acidity, solubility, and polarity. Surrogate recovery, which was used to estimate loss in the extraction stage during pretreatment, was 60%-130%, which was similar to the recovery rate suggested in previous studies [19,20]. In general, the results of the method validation indicate that the method used in this study is adequate for the simultaneous analysis of multiple pharmaceuticals in both the liquid phase and solid phase.…”

“…We observed the influent mass load of antibiotics as 121 g/d for STP A, 303 g/d for STP B, 107 g/d for STP C, and 160 g/d for STP D. The relative distributions in the four plants was low at 3%-5%, but the effluent mass load was 35 g/d for STP A, 111 g/d for STP B, 90 g/d for STP C, and 62 g/d for STP D with a relative distribution of 14%-30%. Wang et al (2018) investigated the relative distributions of antibiotics in seven WWTPs in China, and reported a mean relative distribution of 34% in the influent and 28% in the effluent [20]. While this is higher than the influent relative distribution of antibiotics investigated in this study, the effluent relative distributions in both studies are similar.…”

“…For the fluoroquinolones ofloxacin and ciprofloxacin, the contribution of sludge sorption was 13%-64% and 13%-134%, respectively, which was higher than that of other substances. Studies have reported that sorption accounts for much higher removal of these substances than biodegradation because of the large amount transferred from the liquid phase to the solid phase in the activated sludge and waste sludge [20]. Relatively high adsorption properties were also observed for diphenhydramine and diclofenac.…”

“…This enables a more accurate assessment of the behavior and effective removal of pharmaceuticals. In particular, studies have evaluated the removal characteristics of pharmaceuticals by analyzing the mass balance of unit processes in STPs using various treatment processes, such as CAS, anaerobic-anoxic-oxic (A2O), membrane bioreactor (MBR), aerated lagoon, and oxidation ditch processes [14,[17][18][19][20]. However, the results of previous studies were not comprehensive.…”

In this study, we analyzed 27 pharmaceuticals in liquid and solid phase samples collected from the unit processes of four different sewage treatment plants (STPs) to evaluate their distribution and behavior of the pharmaceuticals. The examination of the relative distributions of various categories of pharmaceuticals in the influent showed that non-steroidal anti-inflammatory drugs (NSAIDs) were the most dominant. While the relative distribution of antibiotics in the influent was not high (i.e., 3%–5%), it increased to 14%–30% in the effluent. In the four STPs, the mass load of the target pharmaceuticals was reduced by 88%–95% mainly in the biological treatment process, whereas the ratio of pharmaceuticals in waste sludge to those in the influent (w/w) was only 2%. In all the STPs, the removal efficiencies for the stimulant caffeine, NSAIDs (acetaminophen, naproxen, and acetylsalicylic acid), and the antibiotic cefradine were high; they were removed mainly by biological processes. Certain compounds, such as the NSAID ketoprofen, contrast agent iopromide, lipid regulator gemfibrozil, and antibiotic sulfamethoxazole, showed varying removal efficiencies depending on the contribution of biodegradation and sludge sorption. In addition, a quantitative meta-analysis was performed to compare the pharmaceutical removal efficiencies of the biological treatment processes in the four STPs, which were a membrane bioreactor (MBR) process, sequencing batch reactor (SBR) process, anaerobic–anoxic–oxic (A2O) process, and moving-bed biofilm reactor (MBBR) process. Among the biological processes, the removal efficiency was in the order of MBR > SBR > A2O > MBBR. Among the tertiary treatment processes investigated, powdered activated carbon showed the highest removal efficiency of 18%–63% for gemfibrozil, ibuprofen, ketoprofen, atenolol, cimetidine, and trimethoprim.

The introduction of large amounts of pharmaceuticals into the environmental waters is well‐documented in literature with their occurrence reported in all different water matrices accessible to humans and animals. At the same time, the increasing consumption of coffee and tea‐based beverages results in the generation of solid waste, which is mostly disposed‐off in the environment. To minimize environmental pollution, coffee and tea‐based materials have been proposed as suitable options to remove pharmaceuticals in environmental waters. Therefore, this article provides a critical review on the preparation and applications of coffee and tea‐based materials in removing pharmaceuticals from contaminated water. In this context, most studies in literature focused on the applications of these materials as adsorbents, while only limited work on their role in degradation of pharmaceuticals is discussed. The successful application in adsorption studies is attributed to high surface areas of adsorbents and the ability to easily modify the adsorbent surfaces by incorporating functional groups that provide additional oxygen atoms, which promote easy interactions with pharmaceuticals. Hence, the adsorption mechanisms are mostly described by hydrogen bonding, electrostatic and π–π interactions with sample pH playing a dominant role in the adsorption process. Overall, the present article focused on the developments, trends and future research direction on the preparations and applications of coffee and tea‐based materials for efficient removal of pharmaceuticals in water. Practitioner Points Review of tea and coffee wastes application for removal of pharmaceuticals in water Key applications in adsorption and degradation of pharmaceuticals in water Removal mostly explained by hydrogen bonding, electrostatic, and π–π interactions Trends, gaps, and future research to be explored are reviewed and highlighted

A review of 82 papers published in 2018 is presented. The topics ranged from detailed descriptions of analytical methods, to fate and occurrence studies, to ecological effects and sampling techniques for a wide variety of emerging contaminants likely to occur in agricultural environments. New methods and studies on veterinary pharmaceuticals, microplastics, and engineered nanomaterials in agricultural environments continue to expand our knowledge base on the occurrence and potential impacts of these compounds. This review is divided into the following sections: Introduction, Analytical Methods, Fate and Occurrence, Pharmaceutical Metabolites, Anthelmintics, Microplastics, and Engineered Nanomaterials.Practitioner points New research describes innovative new techniques for emerging contaminant detection in agricultural settings. Newer classes of contaminants include human and veterinary pharmaceuticals. Research in microplastics and nanomaterials shows that these also occur in agricultural environments and will likely be topics of future work.
