The huge worldwide use of antibiotics triggers the accumulation these substances in sludge from wastewater treatment plants (WWTP) and possible contamination soils amended with it, as well crops growing soils. In this work we analyzed presence amoxicillin (AMO), cefuroxime (CEF), ciprofloxacin (CIP), clarithromycin (CLA), levofloxacin (LEV), lincomycin (LIN), norfloxacin (NOR), sulfadiazine (SUL), trimethoprim (TRI), different WWTPs Galicia (NW Spain), technically treated by waste-managers,...
Veterinary antibiotics are emerging contaminants and enter into soil principally by agricultural application of organic fertilizers. This article presents the results research obtained for analyzed 70 samples fertilizers (pig poultry manure slurry digestate) various classes antibiotics.Doxycycline, oxytetracycline, tetracycline, lincomycin, tiamulin enrofloxacin were found in tested samples. Doxycycline was as a dominant compound, its highest concentration 175 mg/kg pig manure. investigation...
The presence of synthetic glucocorticoids within the aquatic environment has been highlighted as a potential environmental concern they may mimic role endogenous during vertebrate ontogeny. Prednisolone is commonly prescribed glucocorticoid which repeatedly detected in environment. This study investigated impact environmentally relevant concentrations prednisolone (0.1, 1, and 10 μg/L) zebrafish embryogenesis using physiological behavioral end points are known to be mediated by...
Antibiotics are active substances frequently used to treat and prevent diseases in animal husbandry, especially swine poultry farms. The use of manure as a fertilizer may lead the dispersion antibiotic residue into environment consequently development antibiotic-resistant bacteria. Most pharmaceutical ingredients excreted after administration, some cases up 90% consumed dose can be found feces and/or urine parent compound. Therefore, due metabolism their residues easily detected manure. This...
Drug residues are considered environmental contaminants, and their occurrence has recently become a matter of concern. Analytical methods monitoring systems therefore required to control the continuous input these drug into environment. This article presents suitable HPLC-ESI-MS/MS method for simultaneous extraction, detection quantification 13 drugs (antimicrobials, glucocorticosteroids, anti-inflammatories, anti-hypertensives, anti-cancer triphenylmethane dyes) in surface water. A study...
The Commission Regulation 574/2011/EC set up maximum levels of coccidiostats and histomonostats in nonmedicated feed as a consequence carry-over during manufacturing. Carry-over takes place from medicated to production. Similar contamination could also occur for other pharmaceuticals such tetracyclines, group antibiotics commonly employed food production animal. objective this work is present simple fast method the simultaneous detection four tetracyclines (chlortetracycline, doxycycline,...
Environmental pollution due to antibiotics is a serious problem. In this work, the adsorption and desorption of antibiotic cefuroxime (CFX) were studied in four by-products/residues from forestry food industries. For this, batch-type experiments carried out, adding increasing concentrations CFX (from 0 50 µmol L−1) 0.5 g adsorbent. The materials with pH higher than 9 (mussel shell wood ash) those that presented highest percentages, 71.2% (23.1 kg−1) 98.6% (928.0 kg−1). rest adsorbents, was...
A new multi-compound method for the analysis of veterinary drugs, namely tiamulin, trimethoprim, tylosin, sulfadiazine and sulfamethazine was developed validated in medicated feeds. After extraction, samples were centrifuged, diluted Milli-Q water, filtered analysed by high performance liquid chromatography coupled to tandem mass spectrometry. The separation analytes performed on a biphenyl column with gradient 0.1% formic acid acetonitrile water. Quantitative validation done accordance...
The use of medicated feed is a common practice in animal food production to improve health. Tetracyclines and β-Lactams are the groups that most frequently added this type feed. measurement concentration analytes these types samples sometimes due matrix characteristic, manufacturers demanding fast, precise reproducible methods. A rapid confirmatory method based on simple extraction protocol using acidified methanol followed by high performance liquid chromatography coupled tandem mass...
Veterinary drugs are widely and legally used to treat prevent disease in livestock. However, also illegally as growth-promoting agents. To protect the health of consumers, maximum residue limits (MRL) food animal origin have been established listed Regulation 37/2010. According this regulation, more than 300 need be controlled regularly laboratories for residues veterinary drugs. A cost-effective analytical method is very important explains why development multi-residual methods becoming...
