Determination of pesticide residues in honeybees using modified QUEChERS sample work-up and liquid chromatography-tandem mass spectrometry.
Increasing emissions of chemical compounds to the environment, especially of pesticides, is one of factors that may explain present honeybee colony losses. In this work, an analytical method employing liquid chromatography-tandem mass spectrometry (LC-MS/MS) was optimized for the simultaneous screening of 19 pesticides which have not been yet determined in honeybee samples from northern Poland ...
متن کاملDetermination of clothianidin residues in garlic by liquid chromatography–tandem mass spectrometry combined with QuEChERS
Clothianidin, a neonicotinoid insecticide, has been applied to broadly control agricultural pests, such as Delia antique. However, few methods for determination of clothianidin in garlic samples have been published so far. In this study, a rapid, sensitive, and environmental-friendly residue determination method based on QuEChERS for analysis of clothianidin residues in garlic was investigated....

متن کاملEfficiency of QuEChERS approach for determining 52 pesticide residues in honey and honey bees
A comparison between QuEChERS and other pesticide extraction procedures for honey and honey bee matrices is discussed. Honey bee matrix was extracted by solvent based procedure whereas solid phase extraction was the protocol for the honey matrix. The citrate buffered QuEChERS method was used for both matrices. The methods were evaluated regarding cost (equipment and reagents), time, accuracy, p...
متن کاملDetermination of pyrethroid pesticide residues in vegetables by solvent sublation followed by high-performance liquid chromatography.
A novel method is developed for separating and enriching pyrethroid pesticides from vegetables by solvent sublation, and determination of the pyrethroids is performed by high-performance liquid chromatography (HPLC). The effects of organic solvent, pH of the solution, nitrogen flow rate, and sublation time on the sublation efficiency of pyrethroids are investigated in detail, and the optimal co...
