A rapid confirmatory method for monitoring chloramphenicol (CAP) residues in honey, whole milk, and eggs is presented. This method is based on the polymer monolith microextraction (PMME) technique and high-performance liquid chromatography (HPLC)?electrospray ionization mass spectrometry (MS).
when domesticated honeybees interact with wild native bees, they are up to five times more efficient in pollinating sunflowers than when native bees are not present, claims a study by a pair of
An analytical method for the determination of OTC and TC residues in honey was developed. Sample treatment involves an extraction in EDTA-McIlvaine buffer, followed by a solid-phase cleanup step. With regard to the cleanup procedure, different SPE cartridges were evaluated and the results presented.
A simple and rapid analytical method was developed for the determination of lincomycin and tylosin residues in honey as part of field studies examining the efficacy and target animal safety of these antibiotics to control American foulbrood disease in honey bees.
The occurrence of organochlorine compounds in the food chain has already been reported in several studies. This class of organic compounds constitutes one of the most important groups of dangerous organic contaminants.
A confirmatory method for 6 penicillin antibiotics (amoxicillin, ampicillin, penicillin G, oxacillin, cloxacillin, and dicloxacillin) in honey is presented that allows determination and confirmation of identity of the antibiotics at trace levels.
Liquid chromatography?electrospray ionization mass spectrometry methods (LC-ESI-MS and LC-ESI-MS/MS) for the determination of five macrolide antibiotics including spiramycin, tilmicosin, oleandomycin, erythromycin, and tylosin in honey are presented.
Fifty samples of honey collected from local markets of Portugal and Spain during year 2002 were analyzed for 42 organochlorine, carbamate, and organophosphorus pesticide residues.
Streptomycin belongs to the group of aminoglycoside antibiotics. It was utilized in apiculture to protect bees against a variety of bee diseases. It was the aim of this study to develop a highly sensitive LC/MS/MS method, which could be validated, for the quantitative determination of streptomycin in honey.
