Interactions of 15N-Sulfadiazine and Soil Components As Evidenced by 15N-CPMAS NMR.
Anne E. Berns,Herbert Philipp,Hans Lewandowski,Jeong-Heui Choi,Marc Lamshöft,Hans-Dieter Narres +5 more
TL;DR: Results from two independent incubation studies of 15N-labeled sulfadiazines (SDZ) which focused on identifying binding types in bound residues are presented, finding amide bonds and Michael adducts were identified, while formation of imine bonds could be excluded.

Development of QuEChERS-based extraction and liquid chromatography–tandem mass spectrometry method for quantifying flumethasone residues in beef muscle
Ki Hun Park,Jeong-Heui Choi,A. M. Abd El-Aty,Soon-Kil Cho,Jong-Hyouk Park,Ki Sung Kwon,Hee Ra Park,Hyung Soo Kim,Ho-Chul Shin,Mi Ra Kim,Jae-Han Shim +10 more
TL;DR: The method proved to be sensitive and reliable and, thus, rendered an appropriate means for residue analysis studies and was successfully applied to analyze real samples obtained from large markets throughout the Korean Peninsula.

Analytical procedure to simultaneously measure trace amounts of trenbolone acetate and β‐trenbolone residues in porcine muscle using HPLC‐UVD and MS
Xue Liu,A. M. Abd El-Aty,A. M. Abd El-Aty,Jeong-Heui Choi,Sathya Khay,M. I. R. Mamun,Hyang-Rang Jeon,Soon-Ho Lee,Byung-Joon Chang,Chi-Ho Lee,Ho-Chul Shin,Jae-Han Shim +11 more
TL;DR: The current study was undertaken to validate the performance for the determination of both TBA and beta-trenbolone (beta-TB) residues in porcine muscle at concentrations required to monitor compliance with the maximum residue limit (MRL).

The Assessment of Carbendazim, Cyazofamid, Diethofencarb and Pyrimethanil Residue Levels in P. ginseng (C. A. Meyer) by HPLC
TL;DR: In this article, a fast and simple high-performance liquid chromatography (HPLC) method for the simultaneous determination of four pesticides having fungicide properties has been proposed for Panax ginseng, C. A. Meyer grown for 4, 5, or 6 years.
Analysis of benzobicyclon and its metabolite in brown rice and rice straw after field application using liquid chromatography-tandem mass spectrometry.
So Jeong Im,A. M. Abd El-Aty,A. M. Abd El-Aty,Young-Jun Lee,Md. Musfiqur Rahman,Sung-Woo Kim,Jeong-Heui Choi,Jae-Han Shim +7 more
TL;DR: The sensitivity of the developed method was sufficient to ensure reliable determination of benzobicyclon and its metabolite in rice grain and rice straw and field trials with recommended or double the recommended dose revealed that the herbicide could safely be applied to rice and rice Straw.
