Abstract
Urinary metabolites of bis(2-ethylhexyl) phthalate were studied using fast-atom bombardment mass spectrometry (FAB-MS). It was found that th e beta-glucosides of mono(2-ethyl-5-hydroxyhexyl) phthalate and mono(2 -ethyl-5-oxohexyl) phthalate gave radical molecular anions, M-., under negative-ion FAB conditions. This was also shown to occur for the met hyl ester of mono(2-ethylhexyl) phthalate beta-glucuronide, an artefac t formed during the work-up procedure.
