Cleanup Procedure for Determination of Pesticide Residues in Crops Using Charcoal-Florisil Minicolumn

One-Step Chromatographic Cleanup of Chlorinated Hydrocarbon Pesticide Residues in Butterfat. II. Chromatography on Florisil

Determination of Pesticide Residues in Drainage Water

Pesticides are used worldwide within agriculture to protect crops and ensure the quantity and quality of the harvest. However, intensive and inappropriate pesticides application can directly or indirectly affect different parts of the environment, especially water source. Besides the occurrence of pesticides in drinking water, control of pesticide presence in surface and groundwater is also ver...

Determination of Pesticide Residues in Cannabis Smoke

The present study was conducted in order to quantify to what extent cannabis consumers may be exposed to pesticide and other chemical residues through inhaled mainstream cannabis smoke. Three different smoking devices were evaluated in order to provide a generalized data set representative of pesticide exposures possible for medical cannabis users. Three different pesticides, bifenthrin, diazin...

Simultaneous Determination of 17 Pesticide Residues in Rice by GC/MS using a Direct Sample Introduction Procedure and Spiked Calibration Curves

A reliable, rapid and accurate method based on spiked calibration curves and direct sample introduction was developed for determination of 17 pesticide residues in rice by gas chromatography-mass spectrometry single quadrupole selected ion monitoring GC/MS-SQ-SIM. Sample preparation is based on extraction with acetonitrile without clean up. The use of spiked calibration curves for constructing...
