Determination of Chlorantraniliprole Residues in Corn and Soil by UPLC–ESI–MS/MS and Its Application to a Pharmacokinetic Study
A rapid, highly sensitive, and selective method was developed for the determination of the insecticide chlorantraniliprole (CAP) in corn and soil using ultra-performance liquid chromatography–tandemExpand
Enantioselectivity in tebuconazole and myclobutanil non-target toxicity and degradation in soils.
Enantioselectivity may be a common phenomenon in both aquatic toxicity and biodegradation of chiral triazole fungicides, and this should be considered when assessing ecotoxicological risks of these compounds in the environment. Expand
Simultaneous determination of spirotetramat and its four metabolites in fruits and vegetables using a modified quick, easy, cheap, effective, rugged, and safe method and liquid chromatography/tandem
The method is demonstrated to be convenient and reliable for the routine monitoring of spirotetramat and its metabolites in fruits and vegetables and showed excellent linearity for all studied analytes. Expand
Simultaneous determination of five pyrazole fungicides in cereals, vegetables and fruits using liquid chromatography/tandem mass spectrometry.
The sensitive analytical method using quick, easy, cheap, effective, rugged, and safe (QuEChERS) procedure for simultaneous determination of five novel pyrazole fungicides residues in cereals, vegetables, and fruits was developed by liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS).

Chiral fungicide triadimefon and triadimenol: Stereoselective transformation in greenhouse crops and soil, and toxicity to Daphnia magna.
Investigation of the enantioselective degradation and formation of triadimenol in greenhouse tomato, cucumber, and soil under different application modes showed that the compositions of the four product stereoisomers were different and closely dependent on environmental conditions: the most toxic RS-(+)-triadimenol was the most preferentially produced isomer in tomato under foliage treatment.

Enantioselective separation and transformation of metalaxyl and its major metabolite metalaxyl acid in tomato and cucumber.
This is the first evidence of enantioselective transformation of metalaxyl in vegetables, and the results should be considered in future environmental risk and food safety evaluations. Expand
Determination of tebuconazole, trifloxystrobin and its metabolite in fruit and vegetables by a Quick, Easy, Cheap, Effective, Rugged and Safe (QuEChERS) method using gas chromatography with a
The QuEChERS procedure, by using two sorbents (PSA and C18) and the matrix-matched standards, gave satisfactory recoveries and RSD values in different matrices, however, the repeatability and precision of NPD method were better compared with IT-MS. Expand
Enantioselective degradation of chiral insecticide dinotefuran in greenhouse cucumber and soil.
The research provides the first report concerning the enantioselective degradation of dinotefuran enantiomers and the results can be used for understanding the insect-controlling effect and food safety evaluation. Expand
Residue analysis of kresoxim-methyl and boscalid in fruits, vegetables and soil using liquid-liquid extraction and gas chromatography-mass spectrometry.
Concentration levels for residues of the two fungicides in melon samples from field trials collected 7 days after the last application were clearly below the established MRL values. Expand
Residue analysis and persistence evaluation of fipronil and its metabolites in cotton using high-performance liquid chromatography-tandem mass spectrometry
The results of the residual dynamics experiments showed that fipronil dissipated rapidly in cotton plants and soil and that oxidation and photolysis were the main degradation pathways. Expand
