TY - JOUR PY - 2003// TI - Quantitative determination of the hydrolysis products of nitrogen mustards in human urine by liquid chromatography-electrospray ionization tandem mass spectrometry JO - Journal of analytical toxicology A1 - Lemire, Sharon W.

SP - 1 EP - 6 VL - 27 IS - 1 N2 - Nitrogen mustards are a public health concern because of their extreme vesicant properties and the possible exposure of workers during the destruction of chemical stockpiles. A sensitive, rapid, accurate, and precise analysis for the quantitation of ultratrace levels of N-ethyldiethanolamine (EDEA) and N-methyldiethanolamine (MDEA) in human urine as a means of assessing recent exposure to the nitrogen mustards bis(2-chloroethyl)ethylamine and bis(2-chloroethyl)methylamine, respectively, was developed. The method was based on solid-phase extraction, followed by analysis of the urine extract using isotope-dilution high-performance liquid chromatography-mass spectrometry with TurbolonSpray ionization and multiple-reaction monitoring. The method limits of detection were 0.41 ng/mL for EDEA and 0.96 ng/mL for MDEA in 1 mL of urine with coefficients of variation < 10% for both compounds.
