Chromatographic analysis ofcis- andtrans-mevinphos in poisoned wildlife

Micro QuEChERS-based method for the simultaneous biomonitoring in whole blood of 360 toxicologically relevant pollutants for wildlife

“…Many authors have published methods for the analysis of pesticides in wildlife samples, and some of them are based on the QuEChERS method. However, most of them have been designed for the analysis of a relatively low number of compounds belonging to the same chemical group (Allender and Keegan, 1992;Brown et al, 1996;Brown et al, 2005;Bucchia et al, 2015;Sage et al, 2010;Taliansky-Chamudis et al, 2017). This makes it necessary to use several of these methods in a complementary manner to biomonitoring all the relevant environmental chemicals, which is often impossible due to sample limitation.…”

Comparison of supercritical fluid chromatography–tandem mass spectrometry and liquid chromatography–tandem mass spectrometry for the stereoselective analysis of chlorfenvinphos and dimethylvinphos in tobacco

“…A number of methods for the determination of organophosphorus compounds have been reported in the literature [5][6][7][8]. However, few reports have investigated the separation and measurements of E-Z isomers of organophosphorus compounds [9][10][11], especially CFVP and DMVP. The separation of stereoisomers is conducted mainly through normal-phase liquid chromatography (NPLC), which is time consuming and requires large amounts of harmful organic solvents [12][13][14].…”
