SUPPLEMENTARY INFORMATION:
Background: The NIOSH Manual of Analytical Methods (NMAM) was first
published in 1974 and currently contains over 300 methods that can be
used by the occupational safety and health community to measure worker
exposures. 1-Bromopropane is an industrial solvent often used as a
substitute for a number of chlorofluorocarbon solvents which were
withdrawn from use because of their possible damaging effects to the
ozone layer. 3-Bromopropionic acid is a human metabolite of 1-
bromopropane and a proposed biomarker of exposure. An accurate and
precise method was developed for the detection and quantitation of 3-
bromopropionic acid in human urine. This method was published in the
literature (B'Hymer CB, Cheever KL [2004]. J Chromatogr B 802:361-366).
The method was validated by a second laboratory and is proposed for
inclusion in NMAM's 5th Edition.
