Abstract
Tetracycline is one of the most commonly used antibiotics in the world. Eventually, large amounts of this contaminant will enter into the subsurface environment, where a variety of ions exist. In this study, the effects of divalent metal cations (Mg2+, Ca2+, Pb2+ and Cu2+) and inorganic anions (Cl-, NO3-, SO42- and H2PO4-) on the transport of tetracycline in saturated porous media were investigated. Both batch and column experiments were conducted to determine the interactions between tetracycline and sand. Batch sorption experimental results showed that the presence of divalent metal cations could increase the sorption of tetracycline onto sand due to the cation-bridging mechanism. When Na+ was the counterion in the background solution, anions caused a significant decrease in tetracycline sorption owing to the occupation of some adsorption sites by anions and the decrease of electrostatic attraction. Column experiments indicated that the inhibition effects of divalent cations followed the order of Cu2+ > Pb2+ > Ca2+ ≈ Mg2+; the regular pattern might be related to their different complexing strengths. The presence of inorganic anions enhanced the mobility of tetracycline following the order of H2PO4- > SO42- > NO3- > Cl-. Transport-enhancement effects of anions were ascribed to competition between inorganic anions and tetracycline for deposition sites on sand surfaces. However, when Ca2+ was the counterion, the differences in the breakthrough curve of tetracycline among three inorganic anions (i.e., SO42-, NO3- and Cl-) were very small. In this case, the transport-inhibiting effects of anions could be counterbalanced by the transport-enhancement effects of the cation-bridging effect. Also, the two-site nonequilibrium transport model was applied to analyze the transport data. Findings from this study improve our understanding of the transport of tetracycline in saturated aquifer materials.

Abstract
Water hardness is a critical factor that affects oxytetracycline dissolution by chelation with cations. These interactions may lead to impaired dosing and consequently decrease absorption. Moreover, feed present in gastrointestinal tract may interact with antibiotic and alter pharmacokinetic parameters. In the present study, dissolution profiles of an oxytetracycline veterinary formulation were assessed in purified, soft and hard water. Furthermore, oxytetracycline absolute bioavailability, after oral administration of the drug dissolved in soft or hard water, was evaluated in fed and fasted piglets. A maximum dissolution of 86% and 80% was obtained in soft and hard water, respectively, while in purified water dissolution was complete. Results from in vivo study reconfirmed oxytetracycline's very low oral bioavailability. The greatest values were attained when antibiotic was dissolved in soft water and in fasted animals. Statistically significant lower absolute bioavailability was achieved when hard water was used and/or animals were fed. Moreover, Cmax attained in all treatments was lower than MIC90 of most important swine pathogens. For these reasons, the oral use of OTC formulations, that have demonstrated low oral bioavailability, should be avoided to treat systemic diseases in pigs. In the present study, dissolution profiles of an oxytetracycline veterinary formulation were assessed in purified, soft and hard water. Furthermore, oxytetracycline absolute bioavailability, after oral administration of the drug dissolved in soft or hard water, was evaluated in fed and fasted piglets.

Results from in vivo study reconfirmed oxytetracycline's very low oral bioavailability, the lowest value statistically significant was achieved when hard water was used and/or fed animals. The use of low oral bioavailability antibiotics represents a risk factor that might lead to therapeutic failure and antimicrobial resistance, for these reasons the oral use of oxytetracycline to treat systemic diseases in pig production should be avoided.![]()

Abstract
The existence of Cr(VI) and antibiotics in the environment can form the joint contaminant which can be hazardous to the ecosystem. To deal with this, we have explored a plausible method to remove the Cr(VI) and tetracycline (TC) from water by visible light photocatalysis. In this study, a series of reduced graphene oxide@ZnAlTi layered double oxides (rGO@LDO) composites with different doping ratio of rGO were successfully synthesized, which were applied in photocatalytic reduction of Cr(VI) and oxidation of TC. Graphene acts as an electron donor and it can enhance the adsorption of Cr(VI) and TC on the surface of the composites. It's found that the obtained ZnAlTi-LDO composites doped with rGO have higher photo-responsiveness in the visible region. The best-performing rGO@LDO composite (i.e., CGL3) exhibited enhanced visible light-driven photocatalytic Cr(VI) reduction, which was about five times higher than those of ZnAlTi-LDO (without adding hole catcher). The rGO@LDO also showed a satisfactory performance for photocatalytic oxidation of TC with the total organic carbon removal of 80%. However, the doping of rGO did not significantly enhance the removal of TC. The experiment of pH effects demonstrated that acidic pH was favorable to photocatalytic reduction of Cr(VI), while neutral pH was favorable to photocatalytic oxidation of TC. The band structure of ZnAlTi-LDO was first identified, and the EVB and ECB of ZnAlTi-LDO are -2.32 and 0.72 V (vs. RHE). This research provides a feasible method to remove Cr(VI) and tetracycline from water by employing ZnAlTi-LDO doped with rGO as photocatalyst.

Abstract
The role of antibiotics commonly used in fish culture activities in methylmercury (MeHg) formation in mariculture sediments (MS) and in reference sediments (RS) was studied using simulation microcosms. MS and RS were split into three equal batches. Two batches were spiked with Hg(NO3)2 aqueous solution at levels of 2 and 8 mg kg-1 (dry weight basis) and the remainder served as a control batch. Tetracycline (TC) and oxytetracycline (OTC) (2.5 g and 10 g of each) were added to each treatment. Sediment THg concentration decreased during the culture period possibly due to complexation of Hg with the antibiotics resulting in the dissolution of Hg compounds from the sediment. More importantly, the MeHg concentration increased after 32 days together with a decrease in the concentrations of the antibiotics in the sediment. The complexation of TC or OTC with Hg resulted in the transport of electrons from TC or OTC to Hg2+ due to the high electronegativity of Hg2+. Subsequently, Hg2+ was reduced to Hg° which reacted with CH3+ derived from TC or OTC. The use of antibiotics may therefore promote the formation of MeHg in sediments.

Abstract
Wastewater treatment systems are considered as hotspots for release of antibiotic resistance genes (ARGs) into the environment. Anaerobic-aerobic sequential (AAS) bioreactors now are intensively used for wastewater treatment worldwide. However, the occurrence of ARGs in wastewater treatment systems exposed to low-level (i.e., sub-inhibitory) antibiotic is poorly known. Here, we studied the distribution patterns of seven tetracycline resistance genes (tet genes) including tet(A), tet(C), tet(G), tet(X), tet(M), tet(O), and tet(W), as well as one mobile element [class 1 integron (intI1)] in AAS bioreactors under exposure to tetracycline from 50 μg/L to 500 μg/L. Additionally, effect on the removal performance of nutrients and tetracycline in both anaerobic and aerobic units was also investigated. A tetracycline concentration gradient selected for bacterial resistance in the anaerobic reactor, with the exception of tet(A) and tet(W), and the tetracycline removal deteriorated by 47%. However, the abundance of tet and intI1 genes reduced in the subsequent aerobic unit, and the removal of tetracycline, soluble COD, and NH4+-N maintained at average efficiencies of 91%, 90%, and 93%, respectively. The level of tet(X) was largely unaffected by AAS treatment. It is notable that intI1 genes probably played a crucial role on the horizontal dissemination of tet genes. The tetracycline levels and intI1 genes appear to be the primary factors influencing the occurrence of tet genes in AAS bioreactors. Nonetheless, AAS treatments still show promise for reducing antibiotics, ARGs and mobile elements without affecting nutrient removal, and need further research for practical applications.

Abstract
Driven by economic interests, the abuse of antibiotics has become a significant concern for humans worldwide. As one of the most commonly used antibiotics, oxytetracycline (OTC) residue in animal-derived foods occurs occasionally, which has caused danger to humanity. However, there is still no simple and efficient solution to detect OTC residue. Here, an easily-operated colorimetric strategy for OTC detection was developed based on nickel ions (Ni2+) immobilized carboxymethylcellulose/polyacrylonitrile nanofibrous membranes (Ni@CMC/PAN NFMs). Owing to numerous O- and N-containing groups OTC has a strong tendency to complex with Ni2+ on the strips, inducing a color change from light green to yellow visible to the naked eye. The NFMs structural features, CMC functionalization process, and Ni2+ immobilization amount was carefully regulated to assure OTC detection whilst maintaining the inherent characteristics of NFMs. With the benefits of the large specific surface area (SSA) and small pore size of NFMs, the strips not only exhibited a rapid response (2 min), and low detection limit (5 nM) but also performed with good reversibility and selectivity concerning OTC detection over other antibiotics. The successful development of such enchanting nanofibrous materials may provide a new comprehension into the design and improvement of colorimetric strips.

Abstract
Antibiotics are ubiquitous pollutants in aquatic systems and can exist as different dissociated species depending on the water pH. New knowledge of their multivariate photochemical behavior (i.e., the photobehavior of different ionized forms) is needed to improve our understanding on the fate and possible remediation of these pharmaceuticals in surface and waste waters. In this study, the photochemical degradation of aqueous tetracycline (TC) and its dissociated forms (TCH20, TCH-, and TC2-) was investigated. Simulated sunlight experiments and matrix calculations indicated that the three dissociated species had dissimilar photolytic kinetics and photooxidation reactivities. TC2- photodegraded the fastest due to apparent photolysis with a kinetic constant of 0.938 ± 0.021 min-1, followed by TCH- (0.020 ± 0.005 min-1) and TCH20 (0.012 ± 0.001 min-1), whereas TCH- was found to be the most highly reactive toward •OH (105.78 ± 3.40 M-1 s-1), and TC2- reacted the fastest with 1O2 (344.96 ± 45.07 M-1 s-1). Water with relatively high pH (e.g., ~ 8-9) favors the dissociated forms of TCH- and TC2- which are most susceptible to photochemical loss processes compared to neutral TC. The calculated corresponding environmental half-lives (t1/2,E) in sunlit surface waters ranged from 0.05 h for pH = 9 in midsummer to 3.68 h for pH = 6 in midwinter at 45° N latitude. The process was dominated by apparent photolysis (especially in summer, 62-91%), followed by 1O2 and •OH oxidation. Adjusting the pH to slightly alkaline conditions prior to UV or solar UV light treatment may be an effective way of enhancing the photochemical removal of TC from contaminated water. Graphical abstract Aqueous multiple photochemical behavior of dissociated tetracycline (TCH20, TCH-, and TC2-) is first comprehensively reported on revealing the phototransformation kinetics and implications for the fate in surface waters.

Baran W, Adamek E, Jajko M, Sobczak A. Removal of veterinary antibiotics from wastewater by electrocoagulation. CHEMOSPHERE 2018; 194:381-389. [PMID: 29223117 DOI: 10.1016/j.chemosphere.2017.11.165] [Citation(s) in RCA: 65] [Impact Index Per Article: 10.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/19/2017] [Revised: 11/03/2017] [Accepted: 11/28/2017] [Indexed: 06/07/2023]
Abstract
The aim of this study was to assess the effectiveness of veterinary antibiotic removal from wastewater using an electrocoagulation method. The removal efficiency of ampicillin, doxycycline, sulfathiazole and tylosin; the antibiotic degradation degree after electrolysis; and the toxicity and qualitative composition of antibiotic solutions after electrocoagulation were determined in the experiments. HPLC-QTOF was used for quantitative and qualitative determination. The eco-toxicity was assessed using the MARA® assay. After electrocoagulation, the concentration of ampicillin, doxycycline, sulfathiazole and tylosin in wastewater decreased 3.6 ± 3.2%, ∼100%, 3.3 ± 0.4% and 3.1 ± 0.3%, respectively. Doxycycline was the only antibiotic effectively removed from wastewater during electrocoagulation. Simultaneously, part of this antibiotic underwent oxidative degradation. As a result of this process, the eco-toxicity in the reaction environment decreased.

Abstract
The occurrence, fate, mass loading and environmental emission of 37 pharmaceuticals were studied through an integrated approach involving both dissolved and adsorbed phase at a typical wastewater treatment plant in Hunan Province, Southern China. The results displayed the prevalence of 24 and 23 compounds in dissolved phase of influent and effluent, respectively. Fourteen compounds were found adsorbed onto sludge with a mean concentration ranging from 0.85 to 2900μg/kg dry weight. Twelve compounds exhibited high adsorption potential onto suspended particulate matter (SPM) with a mean fraction ranging from 8.8% (trimethoprim) to 97% (tetracycline). Furthermore, SPM showed a diverse absorbability in influent and effluent water circumstance. The overall elimination varied from -16% for lincomycin to 99% for paracetamol, while macrolides were able to withstand the whole treatment process. Mass balance analysis indicated that degradation was the predominant removal pathway for most compounds, and adsorption onto sludge combined with a minor portion of degradation explained for the reduction of tetracyclines and fluoroquinolones, whereas macrolides were recalcitrant to both two processes. The total mass loading was estimated to be up to 2800mg/d/1000 inhabitants and most compounds exhibited lower or comparable level comparing to the global published data. The total environmental emission was estimated up to be 1000mg/d/1000 inhabitants, and a value of 650mg/d/1000 inhabitants was obtained when considering merely the dissolved phase. This work would be helpful for the better understanding of ultimate fate and real pollution of pharmaceuticals in the water environment.

Abstract
Drugs must possess some solubility in water to be therapeutically effective after oral or topical administration to the eye, and drugs must be soluble to be formulated as aqueous solutions for, for example, parenteral delivery. A variety of methods can be applied to enhance aqueous solubility of poorly soluble drugs one of which is the usage of solubilizing complexing agents. There are numerous types of complexes and some are more water-soluble than others. Coordination complexes consist of drugs that act as complexing agents (i.e. ligands) and metal ions (i.e. substrates). Examples of coordination complexes are some water-soluble tetracycline-metal ion complexes. Organic molecular complexes can consist of a small substrate (i.e. the drug) and a small (e.g., caffeine) or a large (e.g., polyvinylpyrrolidone) ligand. In inclusion complexes the substrate is partly or completely enveloped by the complexing agent (e.g., cyclodextrin). Finally, pharmacosomes are drug-phospholipid complexes that can not only enhance aqueous solubility of poorly soluble drugs but also their solubility in organic solvents. This is a mini-review of solubilizing complexing agents that are or can be used in pharmaceutical products.
