“…In the case of the TCs, the residual level is generally lower than that in the manure samples, however not significantly (p<0.05) different among the three types of composts. This implied that TCs might be degraded substantially during the composting process (Kim et al 2012;Selvam et al 2012;Wu et al 2011). Abiotic transformation of the antibiotics might contribute a great to the degradation during composting.…”

“…However, organic fertilizers are applied mainly in the form of composts other than the fresh animal manure. Thus, some degradation of antibiotics is likely to occur during the composting, especially during the exothermic stage (Kim et al 2012). Meanwhile, abiotic reaction with reduced sulfur species could remove the antibiotics from the fresh manures during composting (Zeng et al 2011(Zeng et al , 2012.…”

Veterinary antibiotics (VAs) are emerging contaminants and enter into soil principally by agricultural application of organic fertilizer. A total of 33 solid animal manures and 17 compost samples from protected vegetable farms in nine areas of China were analyzed for the antibiotic classes of tetracyclines, fluoroquinolones, sulfonamides, and macrolides (17 substances in total). Oxytetracycline was found as a dominant compound in the samples, and its highest concentration reached 416.8 mg kg −1 in a chicken manure sample from Shouguang, Shandong Province. Among the samples, animal manures (especially pig manure) contained higher VA residues than composts. However, fluoroquinolones exhibited higher persistence in the compost samples than other antibiotic classes. This is particularly the case in the rice husk compost, which contained the highest level of ofloxacin and ciprofloxacin (1334.5 and 1717.4 μg kg −1 on average, respectively). The veterinary antibiotic profile in the risk husk compost had a good relationship with that in the corresponding manures. The refined commercial compost had the lowest VA residues among the compost samples in general. This implied that composting process might be important to reduce the antibiotic residue. High residue of antibiotics in soil was assumed to be a hazard to ecosystem. This is especially noticeable under current application rates (150 t ha) in protected vegetable farming because over half of the samples exhibited a risk quotient (RQ) >1 for one or more antibiotics.

“…The primary form of treatment for this excrement is composting, including vermicomposting, a process that requires several weeks to months to convert animal feces to useful fertilizers (Lim et al 2015a). However, antibiotics or pharmaceuticals in the manures may not be decomposed completely during the composting process, which can lead to the potential transfer of antibiotics into, or bacterial resistance of soils to which manure-containing fertilizers are applied (Kim et al 2012;Lillenberg et al 2010). Moreover, antibiotics may inhibit the growth of earthworms during the vermicomposting process (Lim et al 2015b).…”

Low-cost adsorbents, e.g., cow manure-based carbon, provide alternatives to remove veterinary antibiotic sulfamethazine (SMT) from contaminated water bodies. In this study, the chemical structures and compositions of cow manure (CM) carbonized at 400, 600, and 800°C (CM400, CM600, and CM800) were examined using elemental analyzer (EA), Brunauer-Emmett-Teller, and spectroscopic techniques. Adsorptions of SMT on CM samples were conducted as functions of pH, hydrophobicity, and ionic strengths. Results of EA and spectroscopic analyses suggested that the raw CM and CM400 samples contained the highest amounts of O-containing groups and aliphatic domains. Amounts of such two chemical groups decreased as carbonization temperatures increased. The specific surface areas and total pore volumes of CM samples increased significantly when the carbonization temperatures exceeded 600°C. SMT adsorption on CM samples could be described essentially by the pseudo-second-order kinetic, intra-particle diffusion, and Freundlich isotherm models. Low pH and ionic strength were favorable for SMT adsorption in CM samples, particularly for the CM800, because a strong p ? -p electron donor-acceptor interaction (p ? -p EDA) was formed between SMT and CM surfaces enriched with hydrophobic domains. Further, the high adsorption affinity of SMT to the CM600 and CM800 samples was attributed in part to their larger surface areas and total pore volumes. Generally, CM-based materials carbonized [600°C showed relatively stable structures and exhibited strong aromatic properties. Moreover, maximum adsorption capacities of SMT on the CM800 sample (37-39 mM/kg) were significantly higher than those of other common adsorbents (0.02-35.93 mM/kg).

BACKGROUND:The current study was to monitor of 9 veterinary antibiotics (ceftiofur, clopidol, florfenicol, sulfamethazine, sulfamethoxazole, sulfathiazole, tetracycline, tiamulin, and tylosin) in manure using liquid chromatographytandem mass spectrometry (LC-MS/MS) in positive and negative electrospray ionization mode. METHODS AND RESULTS: Sample preparation was carried out using Mcllvaine buffer and citrate salts to adjust the pH of the sample followed by purification with dispersive solid phase extraction (d-SPE). Separation of analytes during LC-MS/MS analysis was conducted using an Eclipse Plus C18 column and the mobile phase was in gradient mode with, 0.1% formic acid and 5 mM ammonium formate in methanol (A) and 0.1% formic acid and 5 mM ammonium formate in distilled water (B). The linearity of the matrix-matched calibrations of all tested antibiotics was good, with R 2 determination coefficients ≥ 0.9920. The limit of detection (LOD) and quantifications (LOQ) were 0.1-67.0 g/kg and 0.4-200.0 g/kg, μ μ respectively. Analysis of 13 solid and liquid manure samples taken from the Republic of Korea revealed concentrations less than 0.7 g/kg for tiamulin, 1497.6 μ μ g/kg for sulfamethazine. CONCLUSION: To monitor 9 veterinary antibiotics from manure samples in 13 provincial areas throughout the Republic of Korea, an analytical method was developed. The developed method was fully validated and successfully applied for monitoring various veterinary antibiotics in manure samples.
