Determination of Ethylene Thiourea in Urine by HPLC-DAD [PDF]

open access: yesJournal of Analytical Toxicology, 2005
Ethylene thiourea (ETU) is a metabolite of ethylenebisdithiocarbamates (EBDCs); it is the best indicator of exposure to these fungicides. Therefore, high-performance liquid chromatography with photodiode-array detection (HPLC-DAD) was optimized and validated for the determination of ETU in human urines.
