Validation of the analysis method of 25 pesticide residues in rice using LC-MS/MS device (liquid chromatography-mass spectrometry)
Introduction: In recent years, due to the increase in the use of pesticides in agricultural products and its entry into the human food chain, there has been an increase in concerns about the health of food among people. Therefore, the purpose of conducting this research is to validate the analysis method. 25 pesticide residues in rice using LC-MS/MS. Methods: In this research, a simultaneous an...
متن کاملMulti-Residue Analysis of Pesticide Residues in Crude Pollens by UPLC-MS/MS.
A multi-residue method for the determination of 54 pesticide residues in pollens has been developed and validated. The proposed method was applied to the analysis of 48 crude pollen samples collected from eight provinces of China. The recovery of analytes ranged from 60% to 136% with relative standard deviations (RSDs) below 30%. Of the 54 targeted compounds, 19 pesticides were detected. The ma...
متن کاملIsomer-specific analysis of hexabromocyclododecane by LC/MS/MS
Hexabromocyclododecane (HBCD, C12H18Br6) is the most widely used of the cycloaliphatic BFRs. In 1999, the global demand for HBCD (~16 kilotons) was more than double that of the penta-bromodiphenyl ether (~8.5 kilotons) mixture [1]. HBCD is used as thermal insulation in the building industry, and is the principal flame retardant in extruded (XEPS) and expanded (EPS) polystyrene foams [2]. Second...
متن کاملAssessing Washing Methods for Reduction of Pesticide Residues in Tomatoes and Other Produce Using LC/MS and GC/MS Authors
Various washing protocols have been assessed for efficacy using Agilent LC/MS and GC/MS instrumentation to measure pesticide residues in tomatoes and other produce. Washing procedures in water and various solutions, with and without sonication, were evaluated in the laboratory. In general, the effect of sonication depended on the washing treatment and on the pesticide. A separate experiment mea...
متن کامل[LC-MS/MS analysis of herbicide residues in waters from Navarre].
BACKGROUND The aim of the study was to obtain information on the residues of herbicides (imazametabenz, simazine, isoproturon, clortoluron, metribuzine, atrazine, cianazine, terbutrin, propanil, terbutilazine, alachlor and pendimetalin) present in water proceeding from Navarre. MATERIAL AND METHODS A total of 465 samples of water were taken: 378 were taken from 141 water supplies; the remaini...
